EPA10 DD PLATFORM OPERATORS MANUAL
INTRODUCTION
This manual is intended for use
by the operator of a Detroit Diesel
engine used in On-Highway Vehicle
applications.
Non-Genuine and Rebuilt
Component Quality Alert
Electronic engine controls have
been instrumental in aiding engine
manufacturers in meeting the
stringent emission requirements of
the U.S. Environmental Protection
Agency (EPA) and the California
Air Resources Board (CARB) and
also in meeting the ever-increasing
performance demands of the customer.
Maintenance procedures must
be followed in order to continue
satisfactory performance and
durability and to ensure coverage of
the engine under the manufacturer's
warranty. Many of these maintenance
procedures also ensure that the
engine continues to comply with
applicable emissions standards.
Proper maintenance procedures, using
specific components engineered to
comply with emissions regulations,
may be performed by an authorized
Detroit Diesel distributor or dealer,
an independent outlet or the operator
or owner. The owner is responsible
for determining the suitability of
components to maintain emissions
All information subject to change without notice.
DDC-SVC-MAN-0075
compliance during the engine's useful
emission life.
Detroit Diesel cautions that the
indiscriminate rebuilding of precision
components, without the benefit of
specifications, specialized equipment,
and knowledge of the electronic
operating system, will jeopardize
performance or lead to more serious
problems, and can take the engine
outside of compliance with U.S. EPA
or CARB emissions standards.
There are several other components
in an engine, such as turbocharger,
camshaft, piston, fuel doser valve,
fuel doser block, diesel particulate
filter (DPF), diesel exhaust fluid
pump (for EPA10 engines), which
are specifically designed and
manufactured to exacting standards
for emissions compliance. It is
important that these components, if
replaced, modified or substituted, can
be verified to ensure that the engine
remains in compliance with emissions
standards. The use of inadequately
engineered, manufactured or tested
components in repair or rebuild of
the engine may be in violation of the
federal Clean Air Act and applicable
U.S. EPA or CARB regulations.

INTRODUCTION
Furthermore, modern engines exhibit
operating parameters which require
the use of proper fluids, such as
fuel, coolant and lubricating oil, to
maintain long engine life. The use of
fluids that do not meet Detroit Diesel
specifications may result in premature
wear or engine failure.
Personnel Requirements
Work on the engine should be carried
out only by skilled technicians who
have been instructed in the specific
skills necessary for the type of work
being performed.
Engine Conversions and
Modifications
The function and safety of the engine
could be affected if unauthorized
modifications are made to it. Detroit
Diesel will not accept responsibility
for any resulting damage.
Tampering with the fuel injection
system and engine electronics could
also affect engine power output or
exhaust emission levels. Compliance
with the manufacturer's settings
and with statutory environmental
protection regulations cannot then be
guaranteed.

shows an unusual loss of power, turn
the engine off as soon as possible and
determine the cause of the problem.
Engine damage may be avoided by a
quick response to early indications of
problems.
When starting the engine in cold
weather, refer to section How to Select
Coolant.
System Checks
Perform the following system checks
before starting for the first time.
Checking the Cooling System
Check the cooling system as follows:
1. Make sure all drain cocks in
the cooling system are installed
(drain cocks are often removed
for shipping) and are closed
tightly.
2. Fill the coolant overflow surge
tank with Detroit Diesel Genuine
Coolant until coolant level stays
between the low and full coolant
marks on the tank. For more
detailed recommendations, see
the “How to Select Coolant”
section in this manual.
3. Entrapped air must be purged
after filling the cooling system.
To do this, allow the engine to
warm up with the pressure cap

21
INSTRUCTIONS FOR STARTING THE ENGINE
removed. With the transmission
in neutral, increase engine speed
to 1000 rpm and add coolant to
the surge tank as required.
4. Check to make sure the front of
the radiator and charge air cooler
(if equipped) are unblocked and
free of debris.
Lubrication System Checks
The lubricating oil film on the rotating
parts and bearings of a new or newly
overhauled engine, or one which has
been in storage for six months or
more, may be insufficient when the
engine is started for the first time.
Pre-lubricating the Engine —
To ensure an immediate flow of oil to
all bearing surfaces at initial engine
startup, prepare the engines as follows:
1. Charge the engine lubrication
system with lubricating oil using a
commercially-available pressure
pre-lubricator.
NOTICE:
□ Insufficient lubrication at startup
can cause serious damage to
engine components.
□ Do not add oil if the oil reading
falls on the crosshatch area
of the dipstick. There are
approximately 3.8 L (4.0 qt)
from the fill mark to the full mark.
Overfilling the oil pan can cause
engine damage.
2. After pre-lubricating, check the
engine oil level. If necessary,
top off by filling engine oil no
more than 3.8 L (4.0 qt) at a
time through the oil fill cap to
the satisfactory fill range on the
oil dipstick. Do not overfill. For
lubricating oil recommendations,
refer to section How To Select
Lubricating Oil.
Checking the Oil Level — Check
the oil level as follows:
1. Check the oil level using the
oil dipstick. The oil level is
measured using the crosshatch
area on the dipstick. If the oil
reading is in the crosshatch area,
22
DDC-SVC-MAN-0075
All information subject to change without notice.
Copyright © 2010 DETROIT DIESEL CORPORATION
EPA10 DD PLATFORM OPERATORS MANUAL
then the oil is at the proper level
for engine operation.
NOTE:
If the engine operating temperature is
below 60° C (140° F), the engine must
be on a level surface and then shut
down for 60 minutes for an accurate oil
level reading. Otherwise, the engine
must be brought up to an operating
temperature of 60° C (140° F), parked
on a level surface and then shut down
for five minutes for an accurate oil
level reading.
2. If necessary, top off by filling
engine oil no more than 3.8 L
(4.0 qt) at a time through the
oil fill cap to the satisfactory fill
range on the oil dipstick. Do not
overfill. For detailed procedures,
refer to section “How To Replace
the Lubricating Oil and Oil Filter”
in this manual. Do not overfill.
PERSONAL INJURY
To avoid injury from slipping and
falling, immediately clean up any
spilled liquids.
NOTICE:
Do not add oil if the oil reading is in
the crosshatch area on the dipstick.
There are approximately 3.8 L (4.0
qt) from the fill mark to the full mark.
Overfilling the oil pan can cause
engine damage.
After an Extended Storage —
An engine in storage for an extended
period of time (over winter, for
example) may accumulate water in the
oil pan through normal condensation
of moisture (always present in the air)
on the cold, internal surfaces of the
engine.
NOTICE:
Failure to eliminate water-diluted
lubricating oil may lead to serious
engine damage at startup.
Lubrication oil diluted by water cannot
provide adequate bearing protection
at engine startup. For this reason,
Detroit Diesel recommends replacing
the engine lubricating oil and filters
after extended storage.

INSTRUCTIONS FOR STARTING THE ENGINE
Fuel System Checks
NOTICE:
Make sure the fuel shutoff valve
(if used) is open. Fill the tanks with
the recommended fuel. Keeping
tanks full reduces water condensation
and helps keep fuel cool, which is
important to engine performance.
Full tanks also reduce the chance for
microbe (black slime) growth. For
fuel recommendations, refer to section
How to Select Diesel Fuel.
NOTICE:
Prolonged use of the starting motor
and engine fuel pumps to prime the
fuel system can result in damage
to the starter, fuel pumps, and
injectors. Refer to section Priming
the Fuel System.
If the shutoff valve is even partially
closed, it may cause erratic engine
operation due to an inadequate
supply of fuel to the fuel pump.
NEVER use ether as a starting aid
to run the engine. Doing so will
result in injector damage.
If an external starting aid is used, such
as a starting fluid, the heat generated
by the external fuel source will cause
the injector tips to be damaged when
the fuel cools them. The injector
piston and bushing can be scored from
running without lubrication.
To ensure prompt starting and even
running, the fuel system must be
primed if air has entered the fuel
system. Priming is done by operating
the manual hand priming pump
located on the fuel filter module or
connecting an external priming pump
to the priming port on the fuel filter
module. Refer to section Priming the
Fuel System.
Authorized Detroit Diesel service
outlets are properly equipped for this
type of service.
Priming is required if the fuel system
has been serviced.
BODILY INJURY
To avoid injury from an explosion,
do not use ether or starting fluid
on engines equipped with a
manifold (grid) heater.
Drain off any water that has
accumulated. Water in fuel can
seriously affect engine performance
and may cause engine damage.
Adding Fuel — When adding fuel,
pay attention to the following:

or less, based on ASTM Standard
D 2622 test procedure. Higher
sulfur levels will damage the
Engine Aftertreatment System.
□ Add winter or summer grade fuel
according to the season of the
year.
□ Work in the cleanest conditions
possible.
□ Prevent water from entering the
fuel tank.
For further information,
refer to section How to Select

INSTRUCTIONS FOR STARTING THE ENGINE
Checking the Crankcase
Checking the Turbocharger
Check the crankcase as follows:
Check the turbocharger as follows:
1. If the engine oil was replaced,
stop the engine after normal
operating temperature has been
reached. Allow the oil to drain
back into the crankcase for about
60 minutes, then check the oil
level.
2. If necessary, add oil no more than
3.8 L (4.0 qt) at a time to bring
the level to the proper mark on the
dipstick. Use only the heavy-duty
oils recommended in the “How to
Replace the Lubricating Oil and
Oil Filter” section in this manual.
NOTICE:
Do not add oil if the oil reading
is in the crosshatch area. There
are approximately 3.8 L (4.0 qt)
from the fill mark to the full mark.
Overfilling the oil pan can cause
engine damage.
1. Make a visual inspection of
the turbocharger for oil leaks,
exhaust leaks, excessive noise, or

EPA10 DD PLATFORM OPERATORS MANUAL
The incomplete combustion of
fuel in a cold engine will cause
crankcase oil dilution, formation of
lacquer or gummy deposits on the
valves, pistons, and rings, and rapid
accumulation of sludge in the engine.
When prolonged idling is necessary,
maintain at least 900 rpm.
Stopping the Engine
Stop an engine under normal operating
conditions as follows:
1. Reduce engine speed to idle and
put all shift levers in the neutral
position.
2. Allow the engine to run between
idle and 1000 rpm with no load
for five minutes. This allows
the engine to cool and permits
the turbocharger to slow down.
After five minutes, shut down the
engine.
NOTICE:
Do not stop a turbocharged engine
immediately after a high-speed
operation. Allow a sufficient
cool-down period of about five
minutes to prevent the turbocharger
from continuing to turn without an oil
supply to the bearings or damage
can result.
All information subject to change without notice.
DDC-SVC-MAN-0075
NOTE:
Cool-down idling needs to take place
after pulling off an interstate. When
finding a parking spot or backing into
a dock, immediate shutdown should
be avoided. Shutting the engine off
immediately retains more block heat
than if the engine runs at idle for five
minutes.
Emergency Jump Starting
The engine's electronic system
operates on 12 volts DC. If a DD
Platform engine with an electric
starting motor requires emergency
jump starting, DO NOT EXCEED 16

NOTICE:
Never allow the engine to idle for
more than 30 minutes. Excessive
idling can cause oil to leak from the
turbocharger.
Changing the Idle Speed
The idle speed range of the DD
Platform engine is 600 to 900 rpm if
the parameters in the CPC are set to
the default range.
Change the idle speed as follows:
1. Turn the cruise control switch to
the ON position.
2. To increase the idle speed, push
the RSM/ACC switch until the
idle reaches the desired rpm.
3. To decrease the idle speed, push
the SET/CST switch until the idle
reaches the desired rpm.
Shutting Down the Engine
after High Load Operation
If the engine has been running at full
output or the coolant temperature has
been high, idle the engine for five
minutes without load. If any of the
following conditions occur, shut down
the engine immediately:
36
DDC-SVC-MAN-0075
An engine running at full output or
with high coolant temperature after
a high load operation should idle for
five minutes without load. Shutting
down without idling may cause
damage to the turbocharger.
□ The oil pressure swings back and
forth or falls sharply.
□ Engine power and rpm fall, even
though the accelerator pedal
remains steady.
□ The exhaust pipe gives off heavy
smoke.
□ The coolant and/or oil temperature
climb abnormally.
□ Abnormal sounds suddenly occur
in the engine or turbocharger.
Emergency Running Mode
DD Platform engines are equipped
with an electronic motor control
system which monitors the engine as
it is running.
All information subject to change without notice.
Copyright © 2010 DETROIT DIESEL CORPORATION
EPA10 DD PLATFORM OPERATORS MANUAL
NOTICE:
To prevent possible serious engine
damage, have any faults corrected
without delay by an authorized
service location.
As soon as an engine fault is detected,
it is evaluated and one of the following
measures is initiated.
□ In conjunction with any dashboard
or instrument panel display, the
code for the electronic control
unit reporting the fault can be read
immediately on the display.
□ If the fault is serious enough to
impair normal operation, the
electronic control unit switches
over to a “limp home” mode. The
limp home speed is dependent
on engine control parameters and
could be as low as 1000 rpm. This
allows you to safely move the
vehicle to a service location or a
safe stopping area.
Stop Engine Override
Option
The Stop Engine Override Option
is used for a momentary override.
The electronic engine control system
will record the number of times the
override is activated after an engine
fault occurs.
All information subject to change without notice.
DDC-SVC-MAN-0075
Momentary Override
A Stop Engine Override Switch
is used to override the shutdown
sequence. This override resets the 60
second (30 second for oil pressure)
shutdown timer, restoring power to
the level when the RSL/Stop Engine
was illuminated. The switch must be
recycled after five seconds to obtain a
subsequent override.
NOTE:
The operator has the responsibility to
take action to avoid engine damage.
Cold Weather Operation
Special precautions must be taken
during cold weather. To protect your
engine, special cold weather handling
is required for fuel, engine oil, coolant,
and batteries.

INSTRUCTIONS FOR STARTING THE ENGINE
BODILY INJURY
To avoid injury from an explosion,
do not use ether or starting fluid
on engines equipped with a
manifold (grid) heater.
The engine does not require starting
aids down to 10° C (50° F).
Temperatures below –20° C (–4° F),
will require a block heater and oil pan
heater.
Winter Fronts
A winter front may be used to improve
cab heating while idling. At least 25%
of the grill opening should remain
open in sectioned stripes that run
perpendicular to the charge air cooler
tube flow direction. This assures even
cooling across each tube and reduces
header to tube stress and possible
failure. Winter fronts should only be
used when the ambient temperature
remains below -12° C (10° F).

ELECTRONIC ENGINE CONTROL SYSTEM (DDEC 10)
All engines for 2010 are equipped with
an electronic control system called
Detroit Diesel Electronic Control
(DDEC 10).
The electronic engine control system
regulates the fuel injection quantity
and timing using solenoid valves,
allowing extremely low-emission
operation. Besides the engine and its
related sensors, the system has three
other control modules:
□ Motor Control Module (MCM)
□ Common Powertrain Controller
(CPC)
□ Aftertreatment Control Module
(ACM)
The three control units are connected
by a proprietary datalink through
which all necessary data and
information can be exchanged.
The MCM monitors both the engine
and the datalink. When a malfunction
or other problem is detected, the
system selects an appropriate
response; for example, the emergency
running mode may be activated.
□ The MCM processes the data
received from the CPC, for
example, the position of the
accelerator pedal and engine
brake.
All information subject to change without notice.
DDC-SVC-MAN-0075
□ This data is evaluated together
with the data from the sensors
on the engine, such as coolant
and fuel temperature and oil and
charge pressure. The data is then
compared to the characteristic
maps or lines stored in the MCM.
From this data, quantity and
timing of injection are calculated.
The CPC broadcasts all information
on datalinks. A certified service center
technician can access the CPC via
the datalink using the Detroit Diesel
Diagnostic Link (DDDL) electronic
diagnostic tool.
□ The CPC communicates with the
MCM unit installed on the vehicle
over the proprietary datalink.
□ Data for specific applications is
stored in the CPC. Examples
include idle speed, maximum
running speed, and speed
limitation.
The CPC receives data from several
sources. Examples include:
□ Accelerator pedal position, engine
brake switch
□ Anti-lock brake system and other
electronic control units
□ Oil pressure, coolant temperature
and others, from the MCM
Copyright © 2010 DETROIT DIESEL CORPORATION
39
ELECTRONIC ENGINE CONTROL SYSTEM (DDEC 10)
From this data, instructions are
computed for controlling the engine
and transmitted to the CPC via the
proprietary datalink.
The ACM monitors the Aftertreatment
System (ATS). When a malfunction or
other problem is detected, the system
selects an appropriate response to
deliver to the operator.
Electronic Engine Control
System (DDEC 10)
Features
The electronic engine control system
offers a variety of features and options
designed to warn the operator of
any engine or Aftertreatment System
(ATS) malfunction.
The electronic engine control
system activates the AWL/Check
Engine and the RSL/Stop Engine to
provide a visual warning of a system
malfunction.
Cruise Control
Cruise Control is available with
any Detroit Diesel Electronically
Controlled engine. Cruise Control
will operate in either Engine or
Vehicle Speed Mode and maintain
a targeted speed (mph or rpm) by
increasing or decreasing fueling. The
targeted speed can be selected and
adjusted with dash-mounted switches.
Options can range from warning panel
lights to automatic reduction in engine
power followed by automatic engine
shutdown.
The electronic engine control
system has the ability to perform
diagnostics for self-checks and
continuous monitoring of other
system components.
Depending on the application, the
electronic engine control system
can monitor oil temperature, coolant
temperature, oil pressure, fuel
pressure, coolant level and remote
sensors (if used).
40
DDC-SVC-MAN-0075
Cruise Control may also be
programmed to permit fast idle
using the Cruise Control switches.

Cruise Control will maintain the set
speed under normal road and load
conditions.
LOSS OF VEHICLE CONTROL
To avoid injury from the loss of
vehicle control, do not use cruise
control under these conditions:
□ When it is not possible to
keep the vehicle at a constant
speed (on winding roads, in
heavy traffic, in traffic that
varies in speed, etc.).
□ On slippery roads
(wet pavement, ice-or
snow-covered roads, loose
gravel, etc.).
All information subject to change without notice.
DDC-SVC-MAN-0075
NOTICE:
When descending a hill with Cruise
Control OFF, do not allow the
engine to exceed 2300 rpm. Failure
to observe this can result in over
speeding and serious engine
damage.
Engine speed and power are varied
under Cruise Control to maintain the
set vehicle speed. The vehicle speed
must be above Minimum Cruise Set
Speed and below Maximum Cruise
Set Speed. It is recommended that
Max Cruise Set Speed be set to the
default to allow proper operation of
other features such as Fuel Economy
Incentive and PasSmart. The Vehicle
Speed Limit should be used to limit
vehicle throttle speed.
The Cruise Control cannot limit
vehicle speeds on downgrades if
available engine braking effort is
exceeded, nor can it maintain speed
on upgrades if power requirements
exceed engine power capability.

ELECTRONIC ENGINE CONTROL SYSTEM (DDEC 10)
When the SPD CNTL is in the ON
position, Cruise Control is engaged by
momentarily contacting the SET/CST
Switch. As a check after each engine
start, the electronic engine control
looks for a one-time activation of the
clutch (if equipped) and service brake
before it allows the Cruise Control
to be enabled. The Motor Control
Module (MCM) must also recognize
that the Cruise Enable Switch has
changed. If the Cruise Enable Switch
is OFF, it needs to be turned ON. If the
Cruise Enable Switch is ON, it must
be turned OFF then ON for cruise to
operate.

software. This detailed data (or
DDEC Data) is stored in the CPC
and contains information on engine
performance such as fuel economy,
idle time, and time in top gear. Critical
incidents such as detailed diagnostic
data records and hard braking events
are also stored. DDEC Data can be
downloaded using DDEC Reports
software to produce reports.
DDEC Reports software is part of
the Detroit Diesel Diagnostic Link
(DDDL 7.X) software package.
DDDL 7.X requirements are listed in
the following Table.
Holding the switch in the SET/CST
position allows the vehicle to slow to a
lower speed. Toggling the switch will
result in a one mile-per-hour (1.6 kph)
decrease in vehicle speed. If Cruise
Control has been disabled, toggling
the RSM/ACC Switch restores the
vehicle to the previously set cruise
speed.
Cruise Control can be overridden at
any time with the accelerator pedal if
the vehicle is operating at less than
the programmed Max Road Speed.
Additionally, using either the brake or
the clutch will disable Cruise Control.

LOSS OF VEHICLE CONTROL
Engine Protection
To avoid injury from loss of
vehicle control, do not activate
the Engine Brake system under
the following conditions:
□ On wet or slippery pavement,
unless the vehicle is equipped
with ABS (anti-lock braking
system) and you have had
prior experience driving
under these conditions.
□ When driving without a trailer
(bobtailing) or pulling an
empty trailer.
□ If the tractor drive wheels
begin to lock or there is
fishtail motion after the
Engine Brake is activated,
deactivate the brake system
immediately if this occurs.
The electronic engine control
protection system monitors all engine
sensors, electronic components, and
recognizes system malfunctions. If
a critical fault is detected, the AWL
(Check Engine) and RSL (Stop
Engine) illuminate. The malfunction
codes are logged into the MCM's
memory.
The standard parameters which are
monitored for engine protection
are low coolant level, high coolant
temperature, low oil pressure, and
high oil temperature.
PERSONAL INJURY
To avoid injury from engine
shutdown in an unsafe situation,
ensure the operator knows how
to override the stop engine
condition on a DDEC-equipped
unit.
The engine brake will only operate
when the Accelerator Pedal is fully
released. Disengaging the clutch
will prevent the engine brake from
operating.
The engine brake will supply braking
power even when in Cruise Control.
The Motor Control Module will
control the amount of engine braking
with respect to the Cruise Control
set speed. The maximum amount

NOTICE:
Engines equipped with the power
down/shutdown option have a
system override button or switch to
allow engine operation for a short
period of time. Using the override
button so the engine does not shut
down in 30 seconds but operates
for an extended period may result in
engine damage.
This system features a 30-second,

engine malfunction occurs, such as
low oil pressure, high oil or coolant
temperature, or low coolant level.
California Engine Idle Limiting
2010 Detroit Diesel engines built
with the California (50-state) EPA
certification are allowed to idle
indefinitely when idle speed is below
900 RPM.
For California (50-state) EPA
certification engines that idle above
900 RPM, the California Engine Idle
Limiting feature is enabled. The
engine will generally shut down after
five minutes of continuous idling when
the transmission is in neutral or park
and the parking brake is set or after 15
minutes when the transmission is in
neutral or park and the parking brake
is not set. The automatic shutdown

feature that is applied above 900
RPM is required for all California
certified engines with the exception
of engines used in specific vehicle
types which the state of California
has determined to be exempt from
the idle shutdown requirement.
These include buses, school buses,
recreational vehicles, medium duty
vehicles, military tactical vehicles,
and authorized emergency vehicles
as they are defined by the state of
California. Owners of these vehicle
types that wish to have the shutdown
feature disabled should consult with
California authorities to determine
if their vehicles qualify for the
exemption.
Non-California (49-state) EPA
certification engines (non-California
engines) have the automatic shutdown
feature disabled.
Idle Shutdown Timer
This feature is an optional 1 –
80 minute idle shutdown system.
Its purpose is to conserve fuel by
eliminating excessive idling and
allowing a turbocharger cool-down
period. To activate the shutdown, the
transmission must be in neutral with
the vehicle parking brakes set and the
engine in idle or fast-idle mode.

Operation
NOTE:
This engine is equipped with DDEC
10 software. This software generally
assures optimal engine performance.
The installation of software upgrades
may cause minor changes in features
and engine performance.
Since the DDEC 10 system is
electronic, a battery is required to
operate the computer. The system
operates at 12 volts. However, in the
event of a power supply malfunction,
the system will continue to operate at
reduced voltage. When this occurs,
the AWL (Check Engine) will come
on.
The engine will only operate at
reduced rpm until the battery voltage
reaches a point where the MCM will
no longer function and the engine
shuts down.
46
DDC-SVC-MAN-0075
Should the AWL (Check Engine)
come on for any reason, the vehicle
can still be operated and the driver can
proceed to the required destination.
This condition should be reported
to an authorized Detroit Diesel
distributor or dealer.
NOTICE:
When the RSL (Stop Engine) comes
on, the system has detected a
major malfunction in the engine that
requires immediate attention. It is
the operator's responsibility to
shut down the engine to avoid
serious damage.
The engine can be configured to
give a warning only, to ramp down
(reduce power) or to shut down. Ramp
down will reduce engine rpm to a
predetermined speed, but will not shut
down the engine. With the 30-second
shutdown option, the engine will
begin a 30-second, stepped power
down sequence until it shuts down
completely.
The “Stop Engine Override” feature
can be activated in the case where
the vehicle is operating in a critical
location.

Cruise Control will maintain vehicle
speed even on upgrades, unless power
requirements demand a downshift.
If the Cruise Control/Engine Brake
function is turned ON, the Cruise
Control will limit your speed on
downgrades. Most likely, Cruise
Control will feel stronger than driving
with the accelerator pedal because
of the instantaneous and wide-open
throttle response. That's why Cruise
Control use is not suggested during
slippery driving conditions.
Use Cruise Control after downshifting

system will not allow you to hurt or
over fuel the engine at low or “lug”
engine speeds. There is enough oil
pressure to withstand hard pulls at low
engine speeds.
Engine Brake and Cruise
Control
Your engine is equipped with
both Cruise Control and an engine
brake; the engine brake can operate
automatically while you are in Cruise
Control. If the Cruise Control/Engine
Brake function is turned ON in the
DDEC 10 system programming, the
engine brake will come on “low”
when your set road speed increases
a few mph (kph) above your cruise
set speed. If your speed continues to
increase, the DDEC 10 system will
increase the engine brake's braking
power progressively. When the
vehicle returns to the set cruise speed,
the engine brake will turn off until you
need them.
For safety reasons, don't use Cruise
Control when it is not possible to keep
the vehicle at constant speed due to:
□ Winding roads
□ Heavy traffic
□ Slippery pavement

DDC-SVC-MAN-0075
□ Descending grades calling for
engine brake assistance
For an explanation of the engine
brake system and recommendations
for proper operation, “Engine Brake
System” in this manual.
Shifting Hints
Depending on your transmission
model, the gear split may vary from
400 to 500 rpm. The electronic
governor provides almost no overrun
capability; and, if the transmission
is downshifted too early, you will
experience a temporary loss of pulling
power until the engine speed falls
below rated speed.
In general, when using a 7- or 9-speed
transmission, you should always
downshift between 1150 and 1250
rpm for the DD13 and between 1000
and 1100 rpm for the DD15. This is
true even on steep grades with heavy
loads. When using an 18-, 15-, or
13-speed transmission, you will need
to downshift at an rpm that allows
“less than rated” rpm before throttle
application in the next gear down.
You may want to limit engine speed
to 1900 rpm in all gears. The DD13
engine provides horsepower through
2000 rpm, but fuel economy is not as
efficient above 1800 rpm. The DD15
engine provides horsepower through
2100 rpm, but fuel economy is not as
efficient above 1800 rpm.

If you decide to drive at a lower rpm
for improved fuel economy, don't let
different engine noises throw you
off guard. The engine sounds quiet
at 1400 rpm, almost as if it had quit
pulling. Depending on the air intake
arrangement, you may also experience
a “chuffing” sound as the engine starts
to pull hard at lower rpm. This is
normal and caused by the velocity
changes of the air flow within the air
intake plumbing. Electronic engines
can actually deliver more fuel at lower
engine speeds than at rated speed.
stems and engine surfaces. If you
must idle the engine for cab heat or
cooling, the high idle function of
the Cruise Control switches should
be used. An idle speed of 900 rpm
should be enough to provide cab heat
in above 0° C (32° F) ambients.
The engine has been designed for
a very quiet operation, but the air
flow may be noticeable to the tuned,
attentive ear. The turbocharger
operates at higher boost pressure
forcing EGR gas flow through the
EGR plumbing. In some situations
the driver may believe he/she has
experienced a charge air cooler system
leak. Even connecting trailer light
and air hoses, the driver may hear a
different tone (exhaust and under hood
with the engine idling.) If equipped
with a turbo boost gauge, the driver
may occasionally note intake manifold
pressure exceeds 35 psi (6.89 kPa).
Idling
The common belief that idling a diesel
engine causes no engine damage is
wrong. Idling produces sulfuric acid,
which is absorbed by the lubricating
oil and eats into bearings, rings, valve

when the following conditions are
met:
The engine is equipped with an engine
brake. Before operating the vehicle,
you must familiarize yourself with
the engine brake system to obtain
optimum benefit from it. Engine
brake control systems may vary
slightly, depending on the engine
brake configuration and cab design.
However, basic operator controls are
similar for all models.
□ The Clutch Pedal is out.
Driver Control Switches
□ The Accelerator Pedal is at zero
percent activation.
Vehicles with manual transmissions
allow the driver to turn the engine
brake on and off and select a Low,
Medium, or High level of braking.
Low/Med/High Switch
The “Low” setting on this switch
activates two brake cylinders, yielding
about one-third engine braking
horsepower. The “Medium” activates
four cylinders, supplying about
two-thirds engine braking horsepower.
The “High” setting activates all
six cylinders, providing full engine
braking horsepower.
□ Engine Brake switch is on.
□ An Engine Brake level
(Low/Med/High) is selected.
□ Vehicle meets the programmed
minimum speed.
Engine Brake Operation
NOTICE:
Always allow the engine to reach
full normal operating temperature

Do not attempt to “double clutch”
the transmission while the engine
brake system is turned on. Shifting
gears without pressing the clutch or
using the engine brake to reduce
engine rpm may result in serious
powertrain damage.
After it is switched on, the engine
brake system is automatically
activated each time you remove your
feet completely from the clutch pedal
and accelerator pedal. The engine
brake automatically deactivates itself
when you press the clutch pedal while
shifting gears.
NOTE:
Some systems may be programmed
to activate themselves only when the
brake pedal is pressed, so read your
vehicle owner's manual thoroughly to
find out if you have this option.
Anti-Lock Braking
Systems
Vehicles equipped with ABS have the
ability to turn the engine brake OFF

ENGINE BRAKE SYSTEM
The DDEC 10 system will deactivate
the engine brake system when the
engine speed falls below a preset rpm
or when the vehicle slows down to
a preset speed, depending on DDEC
programming. This prevents stalling
the engine. The engine brake can also
be used with vehicle Cruise Control
turned ON.
Operating on Flat, Dry

to LOW, and then to a higher
position.
Operating Down a Long,
Steep Grade
An explanation of “control speed”
may be helpful in understanding how
to use the engine brake system while
descending a grade. Control Speed
is the constant speed at which the
forces pushing the vehicle forward on
a grade are equal to the forces holding
it back, without using the vehicle
service brakes. In other words, this
is the speed the vehicle will maintain
without using the service brakes or
fueling.
Use the following guidelines when
descending a long, steep grade:
2. If you find you are still using
the service brakes, move the
progressive braking switch to a
higher position until you do not
need to use the service brakes to
slow the vehicle down.
1. Before beginning the descent,
determine if your engine brake
system is operating properly by
lifting your foot briefly off the
accelerator pedal. You should
feel the system activate.
3. If you are carrying a heavier load
and road traction is good, move
the progressive braking switch to
the HIGH position.
2. Ensure the progressive braking
switch is in the appropriate power
position (LOW/MED/HIGH).
4. Check your progressive braking
switch often for proper position,
since road conditions can change

BRAKE FADE
To avoid injury, do not over
apply the vehicle service brakes
when descending a long, steep
grade. Excessive use of the
vehicle brakes will cause them
to heat up, reducing their
stopping ability. This condition,
referred to as “brake fade”, may
result in loss of braking, which
could lead to personal injury or
vehicle/property damage or both.
3. Do not exceed the safe control
speed of your vehicle. Example:
You could descend a 6% grade,
under control only at 10 mph (16
kph) without an engine brake, but
at 25 mph (40 kph) with an engine
brake. You could not descend
that same hill at 50 mph (80 kph)
and still expect to remain under
control. Get to know how much
slowing power your engine brake
can provide. So get to know
your engine brake system before
climbing hills and do not exceed
a safe control speed.

fuel injectors, low and high pressure
pumps, fuel filter module, prefilter,
water separator/coalescer, final filter,
and the necessary connecting fuel
lines. The common rail system with
injectors provides amplification for
better fuel atomization.
Lubrication System
The lubrication system consists of an

is fed to all components via passages
in the engine block and cylinder head.
Air System
Outside air enters the engine through
the air filter and is drawn to the
turbocharger and then is compressed,
and forced through the air-to-air
charge cooler (heat exchanger) and is
cooled. Next, it flows to the intake
manifold and into the cylinders, where
it mixes with atomized fuel from the
injectors.

Parked Regeneration
Procedure
Regeneration of the ATS is
fundamental for the oxidation of
soot. This process happens during
the normal operation cycle of the
vehicle; it can occur both passively
and actively. Regardless of this,
the operator will see no difference
in vehicle performance or vehicle
control. If the ATS is not capable
of completing an over-the-road
regeneration due to duty cycle
constraints or other restrictions, a
parked regeneration may need to
occur. The driver will be notified of
the need for a Diesel Particulate Filter
(DPF) regeneration by illumination of
the DPF Regeneration Lamp.
The DPF Regeneration Lamp may
illuminate after the vehicle has idled
for an extended period of time.
NOTE:
If the DDEC electronics have not
requested the initiation of a parked
regeneration (the DPF Regeneration
Lamp is not illuminated), the Regen
request switch is disabled.
NOTE:
The driver MUST stay with the vehicle
throughout the regeneration process.
All information subject to change without notice.
DDC-SVC-MAN-0075
NOTE:
Not all vehicles may be equipped
with a Regen request switch due to
application or user specification.
NOTE:
The procedure will take 30 to
40 minutes (depending on engine type
and the amount of soot accumulated
in the DPF).
To initiate a parked regeneration,
perform the following:
1. Keep engine at slow idle (cannot
be in PTO mode).
2. Transmission is in neutral with
parking brake ON.
3. Cycle the parking brake from
OFF to ON.
NOTE:
Air tank pressure must be high enough
for the parking brake switch to hold in
the OFF position.
4. Press and release clutch pedal (if
equipped with clutch pedal).
5. Cycle transmission to DRIVE
and back to NEUTRAL (if not
equipped with clutch pedal).
6. Hold DPF Switch in the ON
position for five (5) seconds and
then release (engine speed will
increase and DPF Regeneration
Lamp will go out).

EPA07 Hazardous Applications
When the parked regeneration request
is accepted, the Diesel Particulate
Filter (DPF) Regeneration lamp will
turn ON one time for one second and
then turn off for the remainder of
the parked regeneration. The High
Exhaust System Temperature (HEST)
lamp will flash for one second every
ten seconds and eventually become
solid when the tailpipe temperature is
above 525° C (977° F).
The engine speed will increase to 1100

The regeneration will take 30-40
minutes. The regeneration is complete
when the engine returns to low idle
and the DPF lamp remains OFF. The
HEST lamp will remain ON, but the
vehicle may be driven.
NOTE:
A parked regeneration will STOP and
the engine will return to low idle if any
of the following happens:

EPA10 DD PLATFORM OPERATORS MANUAL
MAINTENANCE
The following guide establishes
preventive maintenance intervals.
These recommendations should
be followed as closely as possible
to obtain long life and optimum
performance from your engine. When
performed on a regular basis, changing
the engine oil, coolant, and filters is
the least costly way of obtaining safe
and reliable vehicle operation. Added
benefits and savings occur when you
check that the valves, fuel injectors,
oil and cooling circuits are in good
working order during oil changes.
Severe Service — Severe service
applies to vehicles that annually travel
up to 30,000 miles (48,000 kilometers)
and average less than 5 miles per
gallon or that operate under severe
conditions.
The intervals shown apply only to
the maintenance functions described.
These functions should be coordinated
with other regularly scheduled
maintenance.
Long Haul — Long Haul service
(over-the-road transport) applies to
vehicles that annually travel more
than 60,000 miles (96,000 kilometers)
and average greater than 6 miles per
gallon with minimal city stop-and-go
operation.
Scheduled Maintenance
Intervals
Before placing your new vehicle
in service, determine the correct
maintenance schedule application for
your intended use of the vehicle.
Maintenance Schedule
Applications
There are three types of maintenance
schedules for the On-Highway
Vehicle applications; Severe Service,
Short-Haul Service, and Long-Haul
Service.
All information subject to change without notice.
DDC-SVC-MAN-0075
Short Haul — Short Haul service
applies to vehicles that annually
travel up to 30,000-60,000 miles
(48,000-96,000 kilometers) and
average between 5.1 and 5.9 miles
per gallon.
Schedule Use
Complete each maintenance operation
at the required interval. The intervals
are based on a collaboration of field
and fleet data. For a more accurate
analysis of when fluids should be
changed, such as engine oil, refer to
publication Engine Requirements –
Lubricating Oil, Fuel and Filters, and
publication Coolant Selections for
Detroit Diesel Engines, available from
authorized Detroit Diesel distributors.

MAINTENANCE
Each maintenance table shows
which maintenance operation must
be performed at the recommended
interval (in miles, kilometers, and
hours).
Additives listed in this manual.
Refer to section How to Select
Coolant.
Refer to section Routine Preventive
Maintenance for a description of the
maintenance to be performed for
related items.
NOTE:
Failure to check and maintain
Supplemental Coolant Additive
levels at required concentrations
will result in severe damage
(corrosion) to the engine cooling
system and related components.
Coolant must be inhibited with the
recommended Supplemental Coolant

Routine Preventive
Maintenance
This section describes the items listed
in the maintenance interval tables.
The “Daily” instructions apply to
routine or daily starting of the engine.
They do not apply to a new engine
or one that has been operated for a
considerable period of time.
Monitoring the Lubricating Oil
Perform the following maintenance on
the lubricating oil:
1. Check the oil level daily. With
the engine stopped, use the oil
dipstick and measure the oil
level on crosshatch area on the
dipstick. If the oil reading is in
the crosshatch area, then the oil
is at the proper level for engine
operation.
All information subject to change without notice.
DDC-SVC-MAN-0075
NOTICE:
If the oil level is constantly above
normal and excess oil has not been
added to the crankcase, consult
with an authorized Detroit Diesel
service outlet for the cause. Fuel or
coolant dilution of lubricating oil can
result in serious engine damage.
NOTE:
If the engine operating temperature is
below 60° C (140° F), the engine must
be on a level surface and then shut

NOTICE:
2. Check the exhaust pipe rain
cap for proper operation, if so
equipped.
Do not allow the air inlet restriction to
exceed 20 in. H2O (5.0 kPa) under
any engine operating conditions.
A clogged air cleaner element will
cause excessive intake restriction
and reduced air supply to the
engine resulting in increased fuel
consumption, inefficient engine
operation, and reduced engine life.
4. Inspect the entire air system for
leaks daily.
[a] Look especially for torn air
inlet piping or boots and
loose or damaged clamps.

Inspection of the Air
Compressor
The air compressor incorporates three
of the major systems of a diesel engine
(air, lubrication, and cooling).
Inspect the air compressor looking for
air, oil, and coolant leaks.
NOTE:
Because the air compressor facilitates
air, lubricating oil, and coolant flow, a
failed air compressor could result in
contamination between these three
fluids. When failed, an air compressor
can produce excessive crankcase
pressure or allow an engine to ingest
lubricating oil.
Monitoring the Fuel and Fuel
Tank
To prevent fuel and fuel tank
problems, the following measures are
recommended:
1. Keep the fuel tank filled to reduce
condensation.
All information subject to change without notice.
DDC-SVC-MAN-0075
2. Before adding fuel,
refer to section How to Select
Diesel Fuel.
3. Refill the tank at the end of
each day's operation to prevent
condensation from contaminating
the fuel. Condensation formed in
a partially filled tank promotes the
growth of microorganisms that
can clog fuel filters and restrict
fuel flow.
4. To prevent microbe growth, add a
biocide to the fuel tank or primary
fuel supply only as needed.
5. Open the drain at the bottom of
the fuel tank every 30,000 miles
(50,000 kilometers) to drain off
any water and/or sediment.
PERSONAL INJURY
To avoid injury from improper use
of chemicals, follow the chemical
manufacturer’s usage, handling,
and disposal instructions.
Observe all manufacturer’s
cautions.
Copyright © 2010 DETROIT DIESEL CORPORATION
95
MAINTENANCE
NOTICE:
Never use galvanized steel fuel
tanks, fittings, pipes, or supply lines.
The fuel reacts chemically with the
zinc coating to form powdery flakes
that can quickly clog the fuel filters
and damage the fuel pumps and
injectors.
6. Every 120,000 miles (200,000
kilometers) or 12 months, tighten
all fuel tank mountings and
brackets. At the same time, check
the seal in the fuel tank cap, the
breather hole in the cap, and
the condition of the flexible fuel
lines. Repair or replace the parts,
as necessary.
Fuel Lines, Flexible Hoses
A pre-start inspection of hoses and
fuel lines is recommended.
Inspection for Fuel Leaks —
Make a visual check for fuel leaks
at all engine-mounted fuel lines and
connections, and at the fuel tank
suction and return lines. Since fuel
tanks are susceptible to road hazards,
leaks in this area may best be detected
by checking for an accumulation of
fuel under the tank.
HOT OIL
To avoid injury from hot oil, do
not operate the engine with the
rocker cover(s) removed.
NOTE:
Leaks are not only detrimental to
machine operation, but they can also
result in added expense caused by the
need to replace lost fluids.
Inspection of Hoses and
Fittings — Check hoses daily as part
of the pre-start inspection.
1. Examine hoses for leaks, and
check all fittings, clamps and ties
carefully.
2. Make sure hoses are not resting
on or touching shafts, couplings,
heated surfaces including exhaust
manifolds, sharp edges, or other
obvious hazardous areas.
3. Since all machinery vibrates and
moves to a certain extent, clamps
and ties can fatigue with age. To
ensure continued proper support,
inspect fasteners frequently
and tighten or replace them as
necessary.
4. If fittings have loosened or
cracked, or if hoses have ruptured

or worn through, take corrective
action immediately.
Inspection of Hoses with
Extended Service Life — A hose
has a finite service life. With this in
mind, inspect hoses as follows:
1. Thoroughly inspect all hoses at
least every 500 operating hours
(1,000 hours for fire-resistant fuel
and lubricating oil hoses) and/or
annually. Look for cover damage
and/or indications of twisted,
worn, crimped, brittle, cracked or
leaking lines. Hoses with their
outer cover worn through or with
damaged metal reinforcements
should be considered unfit for
further service.
2. Replace all hoses in and out of
machinery during major overhaul
and/or after a maximum of five
(5) years of service.
NOTE:
Fire-resistant fuel and lubricating
oil hose assemblies do not require
automatic replacement after five years
of service or at major overhaul, but
should be inspected carefully before
being put back into service.
Inspection of Turbocharger and
Charge Air Cooler
Inspect turbocharger and charge air
cooler as follows:
All information subject to change without notice.
DDC-SVC-MAN-0075
1. Visually inspect the turbocharger
mountings, intake and exhaust

cable clamps (2) at the terminals,
and for corrosion of the terminals
(3). Service or replace as needed.
4. If the engine is to be out of service
for more than 30 days, remove
the batteries and store in a cool,
dry place.
[a] Keep batteries fully charged,
if possible.
[b] Replace any battery that fails
to hold a charge.
5. Periodically check battery
connections for corrosion and
tightness.
[a] If necessary, remove
connections and wire brush
any corrosion from terminals
and cable ends.
[b] Replace damaged wiring.
Engine (Steam Cleaning)
The engine and engine compartment
should be steam cleaned every 60,000
miles (100,000 km) or 2,000 hours,
whichever comes first.

NOTICE:
Do not apply steam or solvent
directly to the battery-charging
alternator, starting motor, DDEC
components, sensors or other
electrical components, as damage
may result.
Battery-Charging Alternator
Precautions must be taken when
working on or around the alternator.
The diodes and transistors in the
alternator circuit are very sensitive
and can be easily destroyed.
To avoid equipment damage, the
following conditions must be met:
Battery Explosion and Acid Burn
To avoid injury from battery
explosion or contact with battery
acid, work in a well ventilated
area, wear protective clothing,
and avoid sparks or flames near
the battery. If you come in contact
with battery acid:
□ Flush your skin with water.
□ Apply baking soda or lime to
help neutralize the acid.
□ Flush your eyes with water.
□ Get medical attention
immediately.
All information subject to change without notice.
DDC-SVC-MAN-0075
□ Avoid grounding the output
terminal. Grounding an alternator
output wire or terminal (which
is always “hot,” regardless
of whether or not the engine
is running) and accidentally
reversing the battery polarity will
result in equipment damage.
□ Do not reverse battery connections.
□ Never disconnect the battery
while the alternator is operating.
Disconnecting the battery can
result in damage to the battery
diodes. In applications which
have two sets of batteries,
switching from one set to the
other while the engine is running
will momentarily disconnect the
batteries.
□ If a booster battery is to be used,
batteries must be connected
correctly (negative to negative,
positive to positive).
□ Never use a fast charger with the
batteries connected or as a booster
for battery output.
For information on the alternator
assembly, contact an authorized
distributor, depending on
manufacturer.

2. Check torque on alternator
mounting bolts and bracketing
every 30,000 miles (50,000 km).
Retighten if necessary.
Lubricating the Fan Hub
If the fan bearing hub assembly has a
grease fitting, use a hand grease gun
to lubricate the bearings with one shot
of quality lithium-based, multipurpose
grease every 120,000 miles (200,000
km).
Care should be taken not to overfill
the bearing housing.
Checking the Vibration Damper
Check the vibration damper as
follows:
2. Heat from normal engine
operation may, over a period of
time, cause the fluid within the
damper to break down and lose
its dampening properties. For
this reason, replace the viscous
vibration damper at time of
normal major engine overhaul,
regardless of apparent condition.
1. Inspect the viscous vibration
damper (1) periodically and
replace if dented or leaking.

HOW-TO PROCEDURES
This section covers Detroit Diesel's
recommendations on how to select
lubricating oil, diesel fuel, and
coolant. Also included are basic
engine maintenance procedures which
can be performed by the operator.
NOTICE:
The manufacturer's warranty
applicable to the engine provides
in part that the provisions of
such warranty shall not apply to
any engine unit that has been
subject to misuse, negligence or
accident. Accordingly, malfunctions
attributable to neglect or failure to
follow the manufacturer's fuel or
lubricating recommendations may
not be within the coverage of the
warranty.
How To Select Lubricating
Oil
NOTICE:
Lubricant Requirements
API CJ-4 oils are recommended for
use in the engine.
Detroit Diesel currently will allow
API CI-4 Plus oil having sulfated ash
levels of 1.4% or less.
Cold Weather Starting
At ambient temperatures below -10°
C (14° F), SAE 5W-30, 10W-30,
5W-40, or 10W-40 oils may be used,
provided they are API CJ-4 and have
demonstrated field performance in
Detroit Diesel engines. These oils
must possess a High Temperature
/ High Shear Viscosity of 3.7 cP
minimum.
Lubricating oil must have a sulfated
ash level less than 1.0 wt %;
currently referred to as CJ-4 oil.
All information subject to change without notice.
DDC-SVC-MAN-0075
Copyright © 2010 DETROIT DIESEL CORPORATION
101
HOW-TO PROCEDURES
NOTICE:
Monograde oils should not be
used in the engine, regardless
of API service classification.
Monograde oils gel at lower ambient
temperatures, reducing lubricant
flow, and do not provide adequate
lubricity at higher engine operating
temperatures resulting in severe
engine damage.
The oils must be API CJ-4 and have
demonstrated field performance in
Detroit Diesel engines.
Detroit Diesel will allow CI-4 Plus oil
having sulfated ash levels of 1.4% or
less.
Use of Synthetic Oils
Synthetic oils may be used in Detroit
Diesel engines, provided they are API
licensed and meet the performance
and chemical requirements of
non-synthetic oils outlined in this
publication. Synthetic oils offer
improved low-temperature flow
properties, high-temperature oxidation
resistance, and improved fuel mileage.
However, they are generally more
costly than non-synthetic oils.
Product information about synthetic
oils should be reviewed carefully.
Performance additive systems often
respond differently in synthetic oils.
102
DDC-SVC-MAN-0075
NOTE:
Synthetic oil does not permit extension
of recommended oil drain intervals.
Use of Supplemental Additives
Lubricants meeting the Detroit
Diesel specifications outlined in this
publication already contain a balanced
additive treatment. Supplemental
additives are generally not necessary
and can even be harmful. These
additives may be marketed as either
oil treatments or engine treatments and
are discouraged from use in Detroit
Diesel engines.
Engine damage resulting from the
use of such materials is not covered
by your Detroit Diesel warranty.
Detroit Diesel will not provide
statements beyond this publication
relative to their use.
Requirements for
Changing Oil
The length of time an engine may
operate before an oil change depends
upon the lubricant and fuel used,
engine oil consumption, and the
operating cycle. For EPA10 engines,
refer to section EPA10 Maintenance
Tables for the tables listing the
recommended oil change intervals.
For EPA07 engines, refer to section
EPA07 Maintenance Tables for the
tables listing the recommended oil
change intervals.

engines, refer to section EPA07
Maintenance Tables.
USED ENGINE OIL
To avoid injury to skin from
contact with the contaminants in
used engine oil, wear protective
gloves and apron.
Disposal of Waste Oil
Used lubricating oil and filters
require deposal in an environmentally
responsible manner, according
to federal (EPA) and/or state
recommendations. The disposal of
waste oil may be best addressed by the
engine oil supplier, who may accept
responsibility for proper disposal of
this material as part of the business of
providing lubricant.
How To Replace the
Lubricating Oil and Oil
Filter
The oil filter is an integral part
of the lubrication system. Proper
filter selection and maintenance
are important to satisfactory engine
performance and service life. The filter
should be used to maintain a clean
system, not to clean up a contaminated
system. The maintenance intervals for
the appropriate duty cycle are listed

full mark. Overfilling the oil pan can
cause engine damage.
NOTE:
If the engine operating temperature is
below 60° C (140° F), the engine must
be on a level surface and then shut
down for 60 minutes for an accurate oil
level reading. Otherwise, the engine
must be brought up to an operating
temperature of 60° C (140° F), parked
on a level surface and then shut down
for five minutes for an accurate oil
level reading.
Fuel quality is an important factor
in obtaining satisfactory engine
performance, long engine life, and
acceptable exhaust emission levels.
In general, fuels meeting the properties
of ASTM Standard D 975 (grades 1-D
and 2-D) have provided satisfactory
performance.
The fuels used must be clean,
completely distilled, stable, and
noncorrosive. For more information
regarding the significance of these
properties and selection of the proper
fuel.
How to Select Diesel Fuel
All DD Platform engines are designed
to operate on Ultra-Low Sulfur Diesel
(ULSD) fuel.

Copyright © 2010 DETROIT DIESEL CORPORATION
EPA10 DD PLATFORM OPERATORS MANUAL
NOTICE:
Use only Ultra-Low Sulfur Diesel
(ULSD) fuel (15 PPM sulfur content
maximum), based on ASTM
Standard D 2622 test procedure.
Using fuel other than ULSD will
damage the Aftertreatment Device.
Fuel Contamination
Generally, fuel contamination
occurs as the result of improper fuel
handling. The most common types
of contamination are water, dirt, and
microbial growth (“black slime”).
The formation of varnishes and
gums resulting from poor stability or
extended storage (“stale fuel”) also
affects fuel quality. The best treatment
for contamination is prevention by
maintaining a clean storage system
and choosing a reputable fuel supplier.
Supplemental additives are not
recommended due to potential
injector system or engine damage.
Our experience has been that such
additives increase operating costs
without providing benefit.
The use of supplemental fuel additives
does not necessarily void the engine
warranty. However, repair expenses
which result from fuel system or
engine component malfunctions or
damage attributed to their use will
not be covered.

Biodiesel Fuel — Detroit Diesel
supports biodiesel as a renewable fuel.
Biodiesel fuels are mono-alkyl esters
of long chain fatty acids commonly
referred to as Fatty Acid Methyl
Esters and are derived from renewable
resources through a chemical process
called transesterification. Detroit
Diesel approves the use of biodiesel
fuel blends up to 5% maximum by
volume in diesel fuel providing the
following three conditions are met:
□ The biodiesel used in the blend
meets ASTM Standard D6751 or
EN 14214 specification.
□ The biodiesel used in the blend
is sourced from a BQ-9000
Accredited Producer.
□ The finished blend meets the fuel
properties ASTM Standard D975
or EN 590 specification.

HOW-TO PROCEDURES
Detroit Diesel is responsible for the
materials and workmanship of its
engines. Failures attributed to the use
of fuels which do not meet industry
standards are not the fault of Detroit
Diesel and will not be covered by
Detroit Diesel product warranty.
While Detroit Diesel supports the use
of B5, the use of unacceptable quality
fuel that does not meet industry
standards can result in warranty
evocation.
Prohibited Additives
drained lubricating oil will increase
maintenance requirements due to filter
plugging and combustion deposits.
Gasoline — The addition of
gasoline to diesel fuel will create a
serious fire hazard. The presence
of gasoline in diesel fuel will reduce
fuel cetane number and increase
combustion temperatures.
FIRE
The following fuel additives are not
allowed and MUST NOT be mixed
with diesel fuel:
To avoid increased risk of a fuel
fire, do not mix gasoline and
diesel fuel.
Used Lubricating Oil — Do not use
fuel blended with used lubricating oil.
Detroit Diesel specifically prohibits
the use of used lubricating oil in diesel
fuel.
Drain and clean tanks which contain a
mixture of gasoline and diesel fuel as
soon as possible.
NOTICE:
Detroit Diesel will not be responsible
for any detrimental effects resulting
from adding drained lubricating oil or
gasoline to the diesel fuel.
Do not burn used lubricating oil
in fuel. It will cause the diesel
particulate filter to prematurely plug
with ash.
Used lubricating oil contains
combustion acids and particulate
materials which can severely erode
fuel injector components, resulting in
loss of power and increased exhaust
emissions. In addition, the use of

How to Replace the Fuel
Filters
NOTICE:
If you have just changed the engine
oil and filter, you MUST start the
engine and confirm proper oil
pressure before changing the fuel
filters. If no oil pressure is shown
after approximately 10 seconds,
stop the engine and determine the
cause. Running the engine with no
oil pressure could result in engine
damage. Start the engine with
the accelerator pedal in the idle
position. Monitor the oil pressure
gauge or indicator lamp. Keep
the engine running at idling speed
until the oil pressure reading is
14 psi (97 kPa) or more.
NOTE:
If you are replacing all three fuel filters,
it is not necessary to run the engine
and test for leaks after installing
each individual fuel filter. However, if
repairing a leak at one filter, complete
that repair and test the system for
leaks after priming the fuel system.
Refer to section Priming the Fuel
System.

and water pump seal failures can result
from the use of coolant or inhibitor
packages based on phosphate.
Automotive Type Coolants —
These coolants generally contain high
levels of phosphate and silicate, offer
no liner pitting protection, and are
not suitable for use in Detroit Diesel
engines.
Methyl Alcohol-Based
Antifreeze — Methyl Alcohol-Based
Antifreeze must not be used because
of its effect on the non-metallic
components of the cooling system and
its low boiling point.
Glycol-Based Coolants
Formulated for HVAC —
These coolants formulated for
Heating/Ventilation/Air Conditioning
(HVAC) should not be used. These
coolants generally contain high levels
of phosphates, which can deposit
on hot internal engine surfaces and
reduce heat transfer.
A small amount of oil adversely
affects heat transfer. For example, a
1.25% concentration of soluble oil
increases fire deck temperature 6%.
A 2.50% concentration increases fire
deck temperature 15%. The use of
soluble oil additives may result in
engine overheating and/or failure.
Chromate Additives — These
additives are not approved for use
in Detroit Diesel engine cooling
systems. Chromate additives can
form chromium hydroxide, commonly
called “green slime.” This, in turn,
can result in engine damage due to
poor heat transfer. Cooling systems
operated with chromium-inhibited
coolant must be chemically cleaned
with a recommended cooling system
cleaner/conditioner (or equivalent
sulfamic acid/sodium carbonate
cleaner) and flushed. Refer to section
Detroit Diesel Genuine Cooling
System Cleaners.
Additives Not Recommended
The following additives are not
recommended for use in Detroit Diesel
engines.
Soluble Oil Additives — These
additives are not approved for use in
Detroit Diesel engine cooling systems.

HOW-TO PROCEDURES
Testing for Supplemental
Coolant Additives
Detroit Diesel Genuine Fluid Analysis
3–Way Coolant Test Strips should
be used to measure nitrite and glycol
concentrations. Refer to section
Detroit Diesel Genuine Fluid
Analysis Products for part numbers.
Cavitation/corrosion is indicated
on the strip by the level of nitrite
concentration. Freeze/boil over
protection is determined by glycol
concentration.
HOT COOLANT
To avoid scalding from the
expulsion of hot coolant, never
remove the cooling system
pressure cap while the engine is
at operating temperature. Wear
adequate protective clothing
(face shield, rubber gloves,
apron, and boots). Remove the
cap slowly to relieve pressure.
1. Dip the strip into coolant for
one second. Remove and shake
briskly to eliminate excess fluid.
2. Immediately compare the pad end
(% glycol) to the color chart on
the container.
3. Sixty seconds (one minute) after
dipping, compare the nitrite pad
to the color chart.
NOTE:
Color change of the additive indicator
(middle pad) indicates the presence of
inhibitor that is not approved by Detroit
Diesel.
4. Promptly replace and tighten the
test strip container cap after each
use. Discard unused strips if they
have turned light pink or tan.
NOTE:
A factory coolant analysis program is
available through authorized Detroit
Diesel service outlets. Refer to “Detroit
Diesel Genuine Coolant Products” for
part numbers.
For best results, take the test while the
coolant is between 10.0 – 60° C (50
– 140° F). Wait at least 60, but not
longer than 75 seconds, before reading
the nitrite level.
Use the test strips as follows:

EPA10 DD PLATFORM OPERATORS MANUAL
Removal of Dropout
Excessive amounts of some inhibitors
in the coolant can cause a gel or
crystalline deposit that reduces heat
transfer and coolant flow. The deposit,
called “dropout,” takes the color of
the coolant when wet, but appears as a
white or gray powder when dry. It can
pick up solid particles in the coolant
and become gritty, causing excessive
wear of water pump seals and other
cooling system components.
Chronic Coolant System
Problems
The most commonly seen coolant
system problems result from
maintenance and formulation factors
such as:
□ Hard water
□ Dilution of the coolant by the
addition of untreated water
□ Over dosage or under dosage of
corrosion inhibitors
□ Improper corrosion inhibitor (most
often phosphated)
PERSONAL INJURY
To avoid injury when using
caustic cleaning agents, follow
the chemical manufacturers
usage, disposal, and safety
instructions.
Remove the wet gel using a nonacid
(alkali) type heavy-duty cleaner,
such as Detroit Diesel Genuine
Cooling System On-Line Cleaner
(sodium nitrite/sodium tetraborate).
Refer to section Detroit Diesel
Genuine Cooling System Cleaners.
NOTE:
If the gel is allowed to dry, it is
necessary to disassemble the
engine and clean it with a caustic
solution or physically clean individual
components.

ENGINE STORAGE
When an engine is to be stored or
removed from operation for a period
of time, special precautions should
be taken to protect the interior and
exterior of the engine, transmission
and other parts from rust accumulation
and corrosion. The parts requiring
attention and the recommended
preparations are given below.
Preparing Engine for
Storage
It will be necessary to remove all
rust or corrosion completely from
any exposed part before applying rust
preventive compound. Therefore,
it is recommended that the engine
be processed for storage as soon as
possible after removal from operation.
The engine should be stored in
a building that is dry and can be
heated during the winter months.
Moisture-absorbing chemicals are
available commercially for use when
excessive dampness prevails in the
storage area.
Temporary Storage (30 Days or
Less)
To protect the engine for a temporary
period of time (30 days or less), follow
this procedure:
All information subject to change without notice.
DDC-SVC-MAN-0075
1. With the engine at ambient
temperature and cool to the touch,
drain engine crankcase oil into a
suitable container. Dispose of the
oil in an environmentally friendly
manner, according to state and/or
federal (EPA) recommendations.
2. Fill the crankcase to the proper
level with the recommended
viscosity and grade of oil.
3. Fill the fuel tank with the
recommended grade of fuel oil.
Operate the engine for two (2)
minutes at 1200 rpm and no load.
Do not drain the fuel system or
the crankcase after this run.
4. Check the air cleaner and service
it, if necessary.
5. If freezing weather is expected
during the storage period,
check the antifreeze/coolant for
required freeze and inhibitor
protection. Add antifreeze
solution to the cooling system
in accordance with Detroit
Diesel's recommendations.
Refer to section How to Select
Coolant in this guide.
NOTE:
If an antifreeze solution is not required
during storage, flush the cooling
system with a good soluble oil (3% –
5% by volume) rust inhibitor to prevent

rusting of the outside diameter of the
cylinder liners.
EYE INJURY
To avoid injury from flying debris
when using compressed air, wear
adequate eye protection (face
shield or safety goggles) and do
not exceed 276 kPa (40 psi) air
pressure.
6. Clean the exterior of the engine
(except electrical parts) with fuel
oil and dry with compressed air.
7. Seal all engine openings. The
material used must be waterproof,
vapor-proof and possess sufficient
physical strength to resist
puncture and damage from the
expansion of entrapped air.
An engine prepared in this manner can
be returned to service in a short time
by removing the seals at the engine
openings and by checking the engine
coolant, fuel oil, lubricating oil and
transmission oil levels.
Extended Storage (More than 30
Days)
To prepare an engine for extended
storage (more than 30 days), follow
this procedure:
136
DDC-SVC-MAN-0075
1. Drain the cooling system and
flush with clean, soft water. Refill
with clean, soft water and add
a rust inhibitor to the cooling
system.
2. Circulate the coolant by operating
the engine until normal operating
temperature is reached.
3. Stop the engine.
4. With the engine at ambient
temperature and cool to the touch,
drain the engine crankcase oil
into a suitable container. Remove
the oil filters. Dispose of the oil
and filters in an environmentally
friendly manner, according
to state and/or federal (EPA)
recommendations. Replace the
drain plug and torque to 45-50
N·m (33-77 lb·ft).
5. Install new lubricating oil
filters. Fill the crankcase to
the proper level with Tectyl®
930A preservative lubricating
oil or an equivalent 30-weight
preservative lubricating oil
meeting Mil-L-21260C, Grade 2

EPA10 DD PLATFORM OPERATORS MANUAL
use a separate, portable supply of
recommended fuel.
NOTE:
If engines are stored where
condensation of water in the fuel
tank may be a problem, additives
containing methyl carbitol or butyl
cellusolve may be added to the fuel.
Follow manufacturer's instructions
for treatment. Where biological
contamination of fuel may be a
problem, add a biocide such as
Biobor® JF (or equivalent) to the
fuel. When using a biocide, follow
the manufacturer's concentration
recommendations and observe all
cautions and warnings.
7. Drain the fuel system and remove
the fuel filters. Dispose of used

plug both to retain the fuel in the
engine.
10. Transmission: Follow the
manufacturer's recommendations
for prolonged storage.
11. Power Take-Off: If equipped,
follow manufacturer's
recommendations for prolonged
storage.
NOTICE:
Failure to properly seal off the
turbocharger air inlet and exhaust
outlet openings before engine
storage may permit air drafts to
circulate through the turbocharger
and rotate the turbine/compressor
shaft without an adequate flow of
lubricating oil to the center housing
bearings resulting in severe bearing
damage.
12. Turbocharger: Since
turbocharger bearings are
pressure lubricated through the
external oil line leading from
the oil filter adaptor while the
engine is operating, no further
attention is required. However,
the turbocharger air inlet and
turbine exhaust outlet connection
should be sealed off with
moisture-resistant tape.
13. Apply a non-friction rust
preventive compound to all
exposed engine parts. If

soda-water solution and rinse
with fresh water. Do not allow
the soda solution to enter the
138
DDC-SVC-MAN-0075
battery. Add distilled water to
the electrolyte (if necessary) and
fully charge the battery. Store the
battery in a cool (never below 0°
C or 32° F) dry place. Keep the
battery fully charged and check
the level and specific gravity of
the electrolyte regularly.
17. Insert heavy paper strips between
the pulleys and drive belts to
prevent sticking.
18. Seal all engine openings,
including the exhaust outlet,
with moisture-resistant tape. Use
cardboard, plywood or metal
covers where practical.
19. Clean and dry the exterior painted
surfaces of the engine and spray
with a suitable liquid automobile
body wax, a synthetic resin
varnish, or a rust preventive
compound.
20. Protect the engine with a good
weather-resistant tarpaulin and
store it under cover, preferably
in a dry building which can be
heated during the winter months.
Outdoor storage of the engine is not
recommended. If units must be kept
out of doors, follow the preparation
and storage instructions already
