On
Check Engine Lamp - Turns
on when a problem exists, but
the vehicle can still be safely
driven. Vehicle should be
serviced to correct the problem
but the situation should not be
considered an emergency.
Engine is Overheating
CAUTION: The cooling
system may overheat if the
engine coolant is at the
minimum level. A sudden
loss of coolant, caused by
a split hose or broken hose
clamp could also lead to an
overheat condition. Always
inspect to ensure hoses and
clamps are not cracked, worn,
or loose. Failure to comply
may result in equipment or
property damage.
NOTE: The system may also
temporarily overheat during
severe operating conditions
such as:
•
Climbing a hill on a hot day.
•
Stopping after
high-speed/high-load
driving.
•
Debris blocking air flow
through the cooling module
(radiator).
NOTE: If the engine coolant
temperature warning lamp
comes on and the audible alarm
sounds showing an overheat
condition, or if you have any
other reason to suspect the
engine may be overheating,
DO NOT TURN OFF THE
ENGINE unless a low water
warning device indicates a loss
of coolant. Follow these steps:
•
Reduce engine speed or
stop. When stopped, place
the transmission in neutral
and set the parking brake.
See the vehicle operator’s
manual for instructions on
transmission shifting and
parking brake information.

WHAT TO DO IF...
•
Check to ensure that the
oil pressure gauge reads
normal.
•
Increase the engine speed
to 1,100 to 1,200 rpm
maximum for 2-3 minutes.
•
Monitor the engine
temperature. After the
temperature returns to
normal, allow the engine
to idle 3–5 minutes before
shutting it off. This allows
the engine to cool gradually
and uniformly.
2
•
•
2-6
If the overheating came
from severe operating
conditions, the temperature
should have cooled by this
time.
Check the coolant level at
the cooling module surge
tank.
WARNING: To reduce
the chance of personal
injury and/or vehicle
damage caused by engine
overheating, never leave
the engine idling when the
vehicle is unattended. If the
engine overheats, immediate
action is required to correct
the condition. Continued
unattended operation of the
engine, even for a short time,
may result in serious engine
damage or a fire. Failure to
comply may result in death,
personal injury, equipment or
property damage.
WARNING: Removing the
surge tank fill cap while
the engine is hot can be
dangerous. Never remove
the surge tank cap while the
engine is still hot; you could
be badly burned. Failure to
comply may result in death,
personal injury, equipment or
property damage.
•
Scalding steam and fluid
under pressure may
escape and cause serious
personal injuries.
•
Wait until the coolant
temperature is below
122°F (50°C).
•
Protect your face, hands,
and arms by covering the
cap with a large, thick
rag to protect against
escaping fluid and steam.
•
Carefully and slowly
turn the cap one turn to
allow excess pressure to
escape, then push down
and turn for final removal.
See the vehicle operator’s
manual for instructions
on checking and filling
the cooling module surge
tank.
WHAT TO DO IF...
CAUTION: Do not allow
your engine to idle, at low
RPMs (400–600 rpm), longer
than 5 minutes. Prolonged
periods of idling after the
engine has reached operating
temperatures can decrease
engine temperature and could
cause engine damage from
inadequate lubrication. The
normal torsional vibrations
generated can also cause
transmission wear. An idle
shutdown feature, available
on PACCAR engines, can
be programmed to shut
the engine down after a
period of low idle operation
with no driver activity. A
flashing warning lamp will
inform the driver of an
impending shutdown. If
the truck is equipped with
PTO equipment, the engine
shutdown system can be
deactivated when the PTO is
operational; however, engine
idle periods should not
exceed 5 minutes whenever
possible. Failure to comply
may result in equipment or
property damage.

Operating Instructions
Engine Operating Range
General Information
CAUTION: Operating the
engine at full throttle below
peak torque will shorten
engine life to overhaul,
can cause serious engine
damage, and is considered
engine abuse. Do not
operate the engine at full
throttle operation below peak
torque rpm for more than 30
seconds. Failure to comply
may result in equipment or
property damage.
3
PACCAR engines are designed to
operate at full throttle under momentary
conditions down to peak torque engine
speed. This is consistent with
recommended operating practices.
3-6
CAUTION: Operating the
engine beyond the maximum
engine speed can cause
severe engine damage. Use
proper operating techniques
for the vehicle to prevent
engine overspeed. The
maximum engine speed
specification is listed
in the “General Engine
Specifications” on page 5-10.
Failure to comply may result
in equipment or property
damage.
Engine Braking System
WARNING: Do not operate
the engine compression
brake when driving/operating
your vehicle bobtail or with
a loaded or unloaded trailer
on road surfaces with poor
traction (wet, icy, or snow
covered roads) or in heavy
traffic. Braking caused by
the normal operation of
the engine compression
brake could cause you to
lose control of the vehicle
resulting in an injury accident.
Failure to comply may result
in death, personal injury,
equipment or property
damage.
WARNING: The service
brakes must be used in an
emergency. The engine
compression brake alone
might not stop the vehicle
Operating Instructions
fast enough to prevent
an accident. The engine
compression brake is NOT
intended as the primary brake
for the vehicle, nor is it an
emergency brake. The engine
compression brake only
helps the service brakes by
using engine backpressure
to slow the drivetrain. Use
the service brakes for quick
stops. You could be seriously
injured if you relied only
on the engine compression
brake to stop the vehicle in an
emergency. Failure to comply
may result in death, personal
injury, equipment or property
damage.
WARNING: Do not use
the compression brake
when operating on road
surfaces with poor traction
(such as wet, icy, or snow
covered roads or gravel).
Compression brakes can
cause the wheels to skid on
a slippery surface. You could
lose control of the vehicle
and/or jackknife if the wheels
begin to skid, resulting in an
accident. Failure to comply
may result in death, personal
injury, equipment or property
damage.
NOTE: If your vehicle is
equipped with anti-lock
brakes (ABS), operation of
the compression brake (if turned
ON) may be interrupted if the
ABS system detects wheel slip
due to operation on slippery
surfaces.
the vehicle down. Because it can
help keep your vehicle’s brakes from
overheating, it can save wear and tear
on the service brakes. However, the
engine compression brake is not an
emergency brake.
Ideally (on normal road surfaces),
you should slow your vehicle with the
compression brake (where permitted
by law) and use the service brakes only
for stopping completely. Operating this
way will greatly prolong the life of the
service brakes.
An engine compression brake is
standard on the PACCAR MX
engine. When activated, the engine
compression brake creates a braking
effect on the drive wheels. This
device uses engine power to slow

on page 4-4.
Refer to the vehicle operator’s manual
instructions for any additional cold
weather starting procedures.
If starting a cold engine, slowly
increase the engine speed. This
provides adequate lubrication to the
bearings and gives ample time to allow
the oil pressure to stabilize.
The use of cold starting aids are
not recommended for ambient
temperatures above 0° F (-18° C).
If an engine must idle for an extended
period of time, it should be done at
a fast idle (1000 rpm maximum) at
coolant temperatures below 150° F
(70° C).
at moderate engine speed until the
engine coolant has reached operating
temperature. Do not let the engine idle
longer than necessary.
CAUTION: Do not operate
the engine at low idle for
long periods of time when
the coolant temperature is
below the normal operating
range. This could result in
the following:
•
Fuel dilution of the
lubricating oil
•
Carbon buildup in the
cylinder
•
Sticking of the valves in
the cylinder head
•
Reduced performance
•
Damage to aftertreatment
components

Normal
Before Stopping the Engine
Monitor the oil pressure and coolant
temperature gauges frequently. Refer
to “Lubricating Oil System” on page
5-11 and “Cooling System” on page
5-12 for recommended operating
pressures and temperatures. Shut
off the engine if any pressure or
temperature does not meet the
specifications.
NOTE: Do not shut off the
engine immediately. A hot
engine stores a great amount of
heat and it does not cool down
immediately after it is shut off.
Always cool the engine down
before shutting it off. You will
greatly increase its service life.
Idle the engine at 1,000 rpm for 4
minutes. Then low idle for 30 seconds
before shutdown. This will allow
circulating coolant and lubricating oil
to carry heat away from the cylinder
head, valves, pistons, cylinder liners,
turbocharger, and bearings. This way
you can prevent engine damage that
may result from uneven cooling.

Electromagnetic
Interference (EMI)
General Information
If not installed correctly, some vehicle
accessories (CB radios, mobile
transmitters, etc.) can generate and
use radio frequency energy that may
cause electromagnetic interference
(EMI) between the accessory and
the electronic controlled fuel system.
Under these conditions, PACCAR
is not liable for any performance
problems with either the fuel system or
the accessory. EMI is not considered
by PACCAR to be an engine failure
and therefore is not warrantable.
Operating Instructions
System EMI Susceptibility
System EMI Radiation Levels
°
PACCAR products are designed
and tested for minimum sensitivity
to incoming electromagnetic energy.
The fuel system EMI susceptibility
has been designed with a high
tolerance against EMI and in most
normal circumstances, if not all,
electromagnetic energy-emitting
devices that meet the Federal
Communications Commission legal
requirements should cause no
interference.
Electronic components are required
to pass various PACCAR and industry
EMI specifications. Our testing
has shown that when the engine is
properly installed and maintained, it
will not interfere with properly installed
onboard communication equipment.
Determine the optimum
antenna location by obtaining
antenna reflective energy data
measurements.
°
Ensure that the optimum
antenna type and mounting
arrangement is being used.
°
Ensure the accessory
equipment is properly
constructed for maximum
filtering to reject incoming
electromagnetic noise.
If any interference condition is noticed,
follow these suggestions to reduce the
amount of EMI:
1.
Locate the accessory receiving
antenna further away.

Fuel Recommendations
General Information
PACCAR is not responsible for
problems caused by non-genuine filters
that do not meet PACCAR performance
or durability requirements.
Contact your local PACCAR authorized
repair location for specific part
numbers.
WARNING: The use of diesel
fuel that has been mixed
with other fuels may cause
an explosion. Do not mix
gasoline, alcohol, or gasohol
with diesel fuel. Make sure
you know your fuel source
and use the recommended
diesel fuel as indicated in this
section of the manual. Failure
to comply may result in death,
personal injury, equipment or
property damage.
CAUTION: Dirt or water in the
fuel system can cause severe
damage to both the fuel pump
and the fuel injectors. Due
to the precise tolerances of
diesel injection systems, it is
extremely important that the
fuel be kept clean and free
of dirt or water. Know your
fuel source and make sure all
steps are taken for dispensing
or using clean fuel in your
vehicle. Failure to comply
may result in equipment or
property damage.
CAUTION: Lighter fuel
can reduce economy or
possibly damage fuel system
components. Lighter fuels
typically do not have enough
lubricity elements in the
fuel to properly lubricate
the fuel injection system.
Be sure you follow the
fuel recommendations as
indicated in this section of
the manual. Failure to comply
may result in equipment or
property damage.
CAUTION: Using diesel fuels
blended with lubricants
may cause damage to your
exhaust aftertreatment
system. Service intervals for

aftertreatment systems will
be reduced. Do not use diesel
fuel blended with lubricating
oil in engines equipped with
an aftertreatment system.
Failure to comply may result
in equipment or property
damage.
CAUTION: Do not use
high-sulfur diesel fuel as
it will damage the exhaust
aftertreatment system. Also,
the engine will not meet
emission regulations. Use
only ultra-low-sulfur diesel
(ULSD) fuel. Failure to comply
may result in equipment or
property damage.
5
CAUTION: If ultra-low-sulfur
diesel fuel is not used,
the engine may not meet
emission regulations, and
damage may occur to the
exhaust aftertreatment
5-14
system. The use of
high-sulfur diesel fuel
will damage the exhaust
aftertreatment system
and impact the engine
emission. Ultra-low-sulfur
diesel fuel is required for
correct operation of the
aftertreatment system. The
engine has been optimized
for use with an aftertreatment
system to meet the 2010 U.S.
Environmental Protection
Agency regulations. Failure
to comply may result in
equipment or property
damage.
NOTE: PACCAR recommends
that the cetane number of diesel
fuel be a minimum of 45 for
engines that are expected to
operate at temperatures below
32°F (0°C) and a minimum of 42
for engines that are operated at
temperatures above 32°F (0°C).
NOTE: Using diesel fuel with
a lower-than-recommended
cetane number can cause
hard starting, instability, and
excessive white smoke. To
maintain satisfactory operation
at low ambient temperatures, it
is important to specify diesel fuel
of the correct cetane number.
NOTE: PACCAR requires
all permissible fuels to have
adequate fuel lubricity. Lubricity
can be determined by ASTM,
specification D6079, ISO 12156,
High Frequency Reciprocating
Rig (HFRR) in which the fuel
must have a wear scar diameter
of 0.02 in. (0.5 mm) or less.
NOTE: The use of

exhaust system. The use of
other grades of diesel fuels
other than Ultra-Low-Sulfur
diesel fuel will be considered
a use of incorrect fuel for
the engine. PACCAR is not
responsible for failures caused
by the use of incorrect fuel, oil
or catalytic reagent or by water,
dirt or other containments in the
fuel or catalytic reagent.
Warranty and the Use of
Biodiesel Fuel
by PACCAR and therefore will not
be covered by the PACCAR engine

PACCAR Inc approves the use of
biodiesel fuel blends up to 5% by
volume in diesel fuel that meets all of
the following three conditions:
•
The biodiesel used in the blend
meets ASTM Standard D 6751 or
EN 14214 specifications.
•
The biodiesel used in the blend
is sourced from a BQ-9000
Accredited Producer.
•
The finished blend meets the fuel
properties of ASTM Standard D

Maintenance Specifications
Lubricating Oil
Recommendations and
Specifications
General Information
CAUTION: Extending the oil
and filter change interval
beyond the recommendations
will decrease the engine
life due to factors such as
corrosion, deposits, and
wear. Engine oil filters
capture dirt and remove
deposits from the oil to
prolong the life of internal
moving components. Follow
the oil and filter change
intervals as recommended in
this section of the manual.
Failure to comply may result
in equipment or property
damage.
5
A major factor in maintaining engine
performance and durability is the
proper use of quality engine lubricating
5-16
oils used in conjunction with the
appropriate oil drain and filter change
intervals. Attempting to extend the oil
and filter change interval beyond the
manufacturers recommendations may
decrease engine life.
NOTE: It is the owners
responsibility to correctly follow
lubricating oil recommendations.
If recommendations are ignored,
the engine warranty could be
affected.
PACCAR recommends the use of
high-quality SAE 15W40 (API CJ-4)
heavy-duty engine oil.
The primary PACCAR
recommendation is for the use of
15W-40 multigrade lubricating oil
for normal operation at ambient
temperatures above 5°F (-15°C).
For ambient temperatures below
5°F (-15°C) SAE 5W30 may be
used, provided it meets API CJ-4
oil specifications and biodiesel or
biodiesel blended fuel is not used as
fuel for the engine. Using a multigrade
oil helps improve engine cranking in
low-temperature conditions, reduces
deposit formation and increases
engine durability.
Maintenance Specifications
New Engine Break-In Oils
Aftermarket Oil Additive Usage
PACCAR does not approve the use of
special “break-in” engine lubricating
oils for new or rebuilt PACCAR
engines. It is recommended to use
the same lubricating oil for engine
break-in that will be used during normal
operation.
PACCAR does not recommend the use
of aftermarket oil additives. Today’s
high-quality engine lubricating oils are
very sophisticated. Most oils already
contain precise amounts of additives
blended into the lubricating oil to meet
stringent performance requirements.
These oils meet performance
characteristics that conform to the
lubricant industry standards and
are sufficient protection when used
according to the recommendations.
Aftermarket lubricating oil additives are
not necessary to enhance engine oil
performance and may in some cases
reduce the oil’s capability to protect
the engine.
Coolant Recommendations
and Specifications
The cooling system in your vehicle
was factory filled with Extended Life
Coolant (ELC) that meets or exceeds
all ASTM D 6210 requirements.
PACCAR recommends only using a
50/50 mixture of distilled water and
ELC when cooling system service
is required. A 50/50 mixture of ELC
and distilled water will provide freeze
protection down to -34°F (- 36.7°C),
which is adequate for most locations
in North America. For extremely cold
operating conditions, a 60/40 mixture
(coolant/water ratio) can be used to
provide freeze protection down to
-62°F (-52.2°C).
Your engine is also equipped with a
Coolant Filter designed to capture
and remove harmful deposits from the
cooling system to help prolong system
life.
5-17

Maintenance Specifications
Checking Coolant Condition
To ensure the Extended Life Coolant
(ELC) in your vehicle always provides
maximum freeze protection, perform
the following tests:
5
1.
Check the coolant color at every
maintenance interval. It should be
a bright red with no signs of debris
or any oil.
2.
Test the freeze point at least two
times a year. A refractometer or
test strips can be used to measure
the protection level.
3.
Keep the cooling system at full
levels by topping-up using ELC
pre-diluted to 50/50 blend.

Replacement Parts
Limitations
PACCAR recommends that any
service parts used for maintenance,
repair or replacement of emission
control systems be new or genuine
approved rebuilt parts and assemblies,
and that the engine be serviced
by an authorized PACCAR Engine
dealer. Your vehicle contains air,
fuel, and electrical components that
may affect engine emission controls.
The use of non-genuine engine or
vehicle replacement parts that are not
equivalent to the PACCAR engine or
OEM vehicle manufacturer’s original
part may impair the engine and vehicle
emissions control system from working
or functioning effectively, and may
jeopardize your emissions warranty
coverage.
Your sole and exclusive remedy
against PACCAR and the Selling
Dealer arising from your purchase and
use of this Engine is limited to the
repair or replacement of “warrantable
failures” at authorized United States
and Canadian PACCAR Engine
Dealers, or an authorized PACCAR
Engine facility where applicable,
subject to PACCAR’s time, mileage,
and hour limitations of the engine
emission warranty. The maximum
time, mileage and hour limitations of
the engine emission warranty begin
running on the Date of Delivery to
the First Purchaser. The accrued
time, mileage, or hours is calculated
when the engine is brought into an
Authorized Dealer for correction of
warrantable failures.
Failures, other than those resulting
from defects in material or factory
workmanship, are not covered by this
6-14
Warranty. PACCAR is not responsible
for failures or damage resulting from
what PACCAR determines to be
abuse or neglect, including, but not
limited to: damage due to accident;
operation without adequate coolants or
lubricants; overfueling; overspeeding;
lack of maintenance of lubricating,
cooling or intake systems; improper
storage, starting, warm-up, run-in or
shutdown practices; unauthorized
modifications of the Engine. PACCAR
is also not responsible for failures
caused by incorrect oil, fuel or diesel
exhaust fluid or by water, dirt or other
contaminants in the fuel, oil or diesel
exhaust fluid. Failure of replacement
parts used in repairs due to the above
non-warrantable conditions is not
warrantable.
PACCAR is not responsible for

Your Warranty Rights and
Obligations
The California Air Resources Board
and PACCAR are pleased to explain
the emission control system warranty
on your 2010 and subsequent model
year diesel engine. In California,
new motor vehicle engines must
be designed, built, and equipped to
meet the State’s stringent anti-smog
standards. PACCAR must warrant
the emission control system on your
diesel engine for the periods of
time listed below provided there has
been no abuse, neglect or improper
maintenance of your diesel engine.
6
Your emission control system may
include parts such as the fuel injection
system and engine electronic control
module. Also included may be hoses,
connectors and other emission related
assemblies.
If an emission-related part on your
engine is found to have a defect in
6-16
material or factory the part will be
repaired or replaced by PACCAR.
This is your emission control system
defects warranty.
Manufacturer’s Warranty Coverage
This warranty coverage is provided for
five years or 100,000 miles (160,000)
km or 3,000 hours of engine operation,
whichever first occurs from the date
of delivery of the engine to the first

Owner’s Warranty Responsibilities
As the engine owner, you are
responsible for the performance of the
required maintenance listed in your
PACCAR Operator’s Manual. You
are responsible for presenting your
engine to an authorized PACCAR
Engine Dealer as soon as a problem
exists. The warranty repairs should be
completed in a reasonable amount of
time, not to exceed 30 days.
PACCAR recommends that you retain
all receipts covering maintenance on
your engine, but PACCAR cannot
deny warranty solely for the lack of
receipts or for the failure to ensure
the performance of all scheduled
maintenance.
As the engine owner, you should also
be aware that PACCAR may deny you
warranty coverage if your engine or a
part has failed due to abuse, neglect,
improper maintenance or unapproved
modifications.
If you have any questions
regarding your warranty rights
and responsibilities, you should
contact the vehicle OEM manufacturer
at the customer center telephone
number provided with your vehicle
operating instructions or the California
Air Resource Board at 9528 Telstar
Avenue, El Monte, CA 91731.
Owner is responsible for downtime
expenses, cargo damage, fines, all
applicable taxes, all business costs,
and other losses resulting from a
Warrantable Condition.
A warranted part which is scheduled for
replacement as required maintenance
is warranted up to the first scheduled
replacement point.
Prior to the expiration of the applicable
warranty, Owner must give notice of
any warranted emission control failure
to an authorized PACCAR Engine
dealer and deliver the engine to such
facility for repair.

Owner is responsible for incidental
costs such as: communication
expenses, meals, lodging incurred by
Owner or employees of Owner as a
result of a Warrantable Condition.

PACCAR Responsibilities
Emergency Repairs
The warranty coverage begins when
the engine is delivered to the first

performed by any authorized PACCAR
Engine dealer using new or genuine
approved rebuilt parts and assemblies.
PACCAR will repair any of the emission
control parts found by PACCAR to

or labor (including diagnosis which
results in determination that there has
been a failure of a warranted emission
control part).
In the case of an emergency where
an authorized PACCAR Engine dealer
is not available, repairs may be
performed by any available repair
location or by any individual using any
replacement parts. A part not being
available within 30 days or a repair
not being complete within 30 days
constitutes an emergency. PACCAR
will reimburse the Owner for expenses
(including diagnosis), not to exceed
the manufacturers suggested retail
price for all warranted parts replaced
and labor charges based on the
manufacturers recommended time
allowance for the warranty repair and
the geographically appropriate hourly
labor rate. Replaced parts and paid
invoices must be presented at an
authorized PACCAR Engine dealer
as a condition of reimbursement for
emergency repairs not performed by
an authorized PACCAR Engine dealer.
