Characteristics of an Engine
with On-Board Diagnostic
General Information
The engines supported by this
manual are required to meet Heavy
Duty On-Board Diagnostics (OBD)
regulations. EPA HD OBD is required
for all U.S. vehicles with a gross
vehicle weight over 6350 kg [14,000
lb].
OBD exists to make sure the engine
is operating within emissions limits.
OBD continuously monitors the engine
and aftertreatment system to detect
malfunctions that adversely affect
emissions. Once a malfunction is
detected, a malfunction indicator lamp
(MIL) illuminates to inform the driver
of the malfunction and a fault code,
which identifies the likely malfunction,
is stored in the engine control module
(ECM).
An OBD system operates in a manner
very similar to the traditional PACCAR
diagnostic system. Both systems
store fault codes, induce derates when
required to protect the engine and
aftertreatment from further damage,
and illuminate dashboard lamps.
These fault codes are used by the
service channel for troubleshooting
and repair.
The differences between an OBD
system and the traditional PACCAR
diagnostic system are that an OBD
system:
•
illuminates the MIL
•
detects deteriorated components
and systems (not just total
malfunctions)
•
performs multiple trip diagnostics
Multiple trip diagnostics are
malfunctions that must occur in
1-13

INTRODUCTION

multiple consecutive trips before the
MIL is illuminated. A trip is a condition
or operating state the engine must
operate for the OBD fault code to
gather information and determine if a
malfunction has occurred. The MIL
turns on when an OBD fault code is
logged, and in most cases, it requires
three trips without a malfunction
occurrence to clear the lamp.
For more information on the MIL and
what the operator should do when
the MIL illuminates, see Malfunction
Indicator Lamp on page 3-4.

serious engine system problem.
WARNING!
This should be considered an emergency. You should stop the vehicle
as safely as possible and turn "OFF"
the ignition. The vehicle must be
serviced and the problem corrected
before driving again. Failure to do so
may result in personal injury, severe
engine damage, equipment or property damage.

come ON.
•
•
If the oil pressure suddenly drops,
or the audible alarm and engine
oil pressure warning light come on
while driving, do the following:
1.
Slow down carefully.
2.
Move a safe distance off the road
and stop.
3.
Place the transmission in
neutral and set the parking
brake. (See Parking Brake
Valve and OPERATING THE
TRANSMISSION in your
vehicle Operator's Manual,
for transmission shifting and
parking brake information.)
4.
Turn "OFF" the engine.
CAUTION
Continuing to operate your vehicle with insufficient oil pressure
may cause severe engine damage,
equipment or property damage.
•
2-4
If the oil pressure fails to rise within
10 seconds after the engine starts,
stop the engine and determine the
cause.
See Lubricating Oil System on
page 5-17, for the correct oil
pressure ranges for your vehicle's
engine.
5.
Turn "ON" the emergency flasher
and use other warning devices to
alert other motorists.
6.
Wait a few minutes to allow oil
to drain into the engine oil pan,
and then check the oil level. (See
Inspection of the Engine Oil Level
on page 5-3.)
7.
Add oil if necessary. If the problem
persists, contact an authorized
PACCAR engine dealer as soon
as possible.
WHAT TO DO IF...
Check Engine Lamp Turns
On
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.
The 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.
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:
1.
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.
2.
Check to ensure that the oil
pressure gauge reads normal.
3.
Increase the engine speed to
1,100 to 1,200 rpm maximum for
2-3 minutes.
4.
Monitor the engine temperature.
After the temperature returns to
NOTE
The system may also temporarily
overheat during severe operating
conditions such as:
•
Climbing a hill on a hot day.
•
Stopping after high-speed/highload driving.
•
Debris blocking air flow through
the cooling module (radiator).

WHAT TO DO IF...
normal, allow the engine to idle
3-5 minutes before shutting it off.
This allows the engine to cool
gradually and uniformly.
2
5.
If the overheating came from
severe operating conditions, the
temperature should have cooled
by this time.
6.
Check the coolant level at the
cooling module surge tank.
Removing the surge tank fill cap while
the engine is too hot is dangerous.
Scalding steam and fluid under
pressure may escape and cause
serious personal injuries. When
removing the surge tank fill cap, follow
these steps:
1.
Wait until the coolant temperature
is below 122°F [50°C].
2.
Protect your face, hands, and
arms by covering the cap with a
large, thick rag to protect against
escaping fluid and steam.
3.
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.
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.
2-6
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.
WHAT TO DO IF...
CAUTION
NOTE
Do not allow your engine to idle,
at low rpm's (400-600 rpm), longer
than five minutes.
Long periods of idling after the engine has
reached operating temperatures
can decrease engine temperature
and cause gummed piston rings,
clogged injectors, and possible engine damage from lack of lubrication. The normal torsional vibrations
generated by the engine can also
cause transmission wear.
If an
engine must idle for an extended
period of time, it should be done at
fast idle (1,000 rpm or greater).
An idle shutdown feature, available
on PACCAR Engines, can be programmed to shut the engine down
after a period of low idle speed operation with no driver activity. A
flashing warning lamp will inform the
driver of an impending shutdown.

NOTE
The power take off (PTO) feature,
available on PACCAR engines, can
be programmed to adjust engine idle
speed with the use of switches to
pre-programmed set points.

Information
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.
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 5-16. Failure to comply may result in equipment or property damage.

Sliding Nozzle
This engine may be equipped with a
variable geometry turbocharger (VGT)
with an exhaust brake feature. This
feature allows the variable geometry
turbocharger to act as an exhaust
brake by retarding the speed of the
engine to provide additional vehicle
braking power and extend the life
of the vehicle service brakes. The
OPERATING INSTRUCTIONS
ON/OFF function is controlled by a
switch located on the dash of the
vehicle. The engine (VGT) exhaust
brake works by retarding engine
speed by creating high exhaust
back pressure. This back pressure
is obtained by restricting airflow
through the turbine housing of the
turbocharger. This restriction through
the turbine housing of the turbocharger
is created through positioning of the
sliding nozzle (1) located internally to
the variable geometry turbocharger
(VGT). the position of the sliding nozzle
is controlled by the engine electronic
control module (ECM). This option
may not be available on your vehicle.
WARNING!
WARNING!
The exhaust brake is not intended
as the primary brake for the vehicle,
nor is it an emergency brake. The
service brakes must be used in an
emergency. Relying solely on the
exhaust brake to stop the vehicle in
an emergency could cause an accident and lead to personal injury. The
exhaust brake only helps the service
brakes by using pressure to slow the
drive train. You must use the service brakes for quick or emergency
stops. Failure to comply may result
in death, personal injury, equipment
or property damage.
Do not use the exhaust brake when
operating on surface with poor traction (such as wet, icy or snow covered roads). Retarders can cause
the wheels to skid on a slippery surface. You could lose control of the
vehicle and jacknife if the wheels
begin to skid, resulting in an accident. Failure to comply may result
in death, personal injury, equipment
or property damage.

WARNING!
NOTE
WARNING!
Do not use an exhaust brake when
driving bobtail or with an unloaded
trailer. There may not be enough
weight on the rear axle to provide
traction. This could cause a loss
of control and jackknife resulting in
an injury accident. Make sure the
exhaust brake is switched "OFF"
when bobtailing or with an unloaded
trailer. Failure to comply may result
in death, personal injury, equipment
or property damage.
When the engine (VGT) exhaust
brake switch is in the "ON" position,
the engine's electronic control module (ECM) monitors inputs (such as
accelerator pedal position and engine speed). From these inputs, the
ECM determines when to enable the
engine (VGT) exhaust brake feature
when the proper braking conditions
are present.
To reduce the possibility of personal
injury or property damage, always
be prepared to use the vehicle service brakes for emergency stopping.
The safe control speed of a vehicle
will vary with the size of the load,
the type of load, the grade, and the
road conditions. Failure to comply
may result in death, personal injury,
equipment or property damage.
Other features/switches like cruise
control, can also affect when the
engine (VGT) exhaust brake activates.
For more information on how the
engine (VGT) exhaust brake functions,
refer to vehicle operation manual or
contact a PACCAR Authorized Repair
Location.
NOTE
3-10
The exhaust brake can only be activated when the accelerator pedal is
at its low idle position. With the throttle at low idle position, fueling commands to the cylinders will not detract from the braking power of the
brake system.
OPERATING INSTRUCTIONS
NOTE
CAUTION
The engine (VGT) exhaust brake is
designed to assist the vehicle's service brakes when slowing the vehicle to a stop.
Exceeding governed engine speed
can cause engine damage. Operating the engine beyond the maximum engine speed may cause serious engine damage and is considered engine abuse. Use the engine
and vehicle braking systems to control engine speed.
Vehicle service brakes must always be
used. The engine brake is not intended
to be used as the primary brake of the
vehicle, nor is it an emergency brake.
The engine retarder only helps the
service brakes by using pressure to
slow the drivetrain. Use the service
brakes for quick stops.

OPERATING INSTRUCTIONS
The optimum braking power of the
engine (VGT) exhaust brake is reached
at rated engine speed. Correct gear
selection, therefore, is critical.

Typically, on vehicles equipped with
automatic transmissions, the engine
electronic control module (ECM) and
the transmission will determine the
correct gear selection.

to overheat and can damage the
starter motor. Never engage the
starter motor for more than 30 seconds and wait 2 minutes between
each attempt to start the engine
to allow the starter motor to cool.
This caution does not apply to air
starters.
NOTE
Engines equipped with air starting
motors require a minimum of 480
kPa [70 psi].
DRIVING INSTRUCTIONS
CAUTION
The engine must have adequate oil
pressure within 15 seconds after
starting the engine. If the oil pressure gauge does not register the
minimum pressure, or drops below
the minimum pressure, a red warning light in the gauge will come on,
a warning buzzer will sound, and
the Stop Engine Lamp will come
on. This should be considered an
emergency. Operating the engine
in this condition may cause severe
engine damage. You should stop
the vehicle as safely as possible.
The vehicle must be serviced and
the problem corrected before driving
again.
Idle the engine 3 to 5 minutes before
operating with a load.
After starting a cold engine, increase
the engine speed (rpm) slowly to
provide adequate lubrication to the
bearings and to allow the oil pressure
to stabilize.
4-7
4
DRIVING INSTRUCTIONS
NOTE
For engines equipped with the engine warm-up protection feature;
this feature limits engine speed and
torque following engine start-up until
sufficient oil pressure is available to
the engine components. This feature reduces the risk of engine part
damage due to operating at engine
speeds too high or loads before adequate oil pressure is achieved.
4
Some engines are equipped with a
Fast Idle Warm Up feature. When
enabled, this feature elevates the idle
speed of the engine in cold ambient
conditions, in order to shorten the time
necessary to warm up the engine.
When the idle speed is elevated, the
engine noise may change, this is
normal. To bring the engine back to
low idle speed:
4-8
•
For vehicles equipped with a
manual transmission and clutch
switch: Depress the clutch pedal.
•
For vehicles equipped with a brake
switch: Depress the service brake
pedal.
•
Depress the accelerator pedal.

Warm Up feature, contact a PACCAR
authorized repair location.
CAUTION
Do not operate the engine at low idle
for long periods with engine coolant
temperature below the minimum
specification in “Cooling System” on
page 5-18. This can result in the
following:
•
Fuel dilution of the lubricating oil.
•
Carbon build up in the cylinder.
•
Cylinder head valve sticking.
•
Reduced performance.
If an engine must idle for an extended period of time, it should
be done at fast idle (1,000 rpm or
greater) until the coolant temperature meets the specification.

pressures and temperatures. Shut
off the engine if any pressure or
temperature does not meet the
specifications.
Engine Overheating
Continuous operation with engine
coolant temperature above or below
the engine coolant temperature
specifications listed in “Cooling
System” on page 5-18 can damage
the engine.
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.
4
NOTE
The system may also temporarily
overheat during severe operations
conditions such as:
4-10
•
Climbing a hill on a hot day.
•
Stopping after high-speed/highload driving.
•
Debris blocking air flow through
the cooling module (radiator).
DRIVING INSTRUCTIONS
NOTE
If an overheating condition starts to
occur, reduce the power output of the
engine by releasing the accelerator
pedal or shifting the transmission
to a lower gear, or both, until the
temperature returns to the normal
operating range. If the engine
temperature does not return to
normal, shut off the engine, and refer
to Troubleshooting Symptoms, or
contact a PACCAR Authorized Repair
Location.
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:
1.
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.
2.
Check to ensure that the oil
pressure gauge reads normal.
3.
Increase the engine speed to
about one-half of full operating
speed, or 1,100 to 1,200 rpm,
maximum for 2-3 minutes.
4.
Return the engine speed to normal
idle after two or three minutes.
5.
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.
6.
If the overheating came from
severe operating conditions, the
temperature should have cooled
by this time.
7.
Check the sight gauge (glass
level indicator) on the side of the
coolant expansion tank.

arms by covering the cap with a
large, thick rag to protect against
escaping fluid and steam.
3.
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.
Take the time to learn what normal
operating conditions are for your
engine so that when an abnormal
condition arises, you will be able to
recognize it as such and take the
appropriate action.
Most failures give an early warning.
Look and listen for changes in
performance, sound, or engine
appearance that can indicate service
or engine repair is needed. Some
changes to look for are:
•
Engine misfires.
•
Vibration.
•
Unusual engine noises.
•
Sudden changes in engine
operating temperatures or
pressures.
•
Excessive smoke.
•
Loss of power.
DRIVING INSTRUCTIONS
•
An increase in oil consumption.
•
An increase in fuel consumption.
•
Fuel, oil, or coolant leaks.
CAUTION
Do not allow your engine to idle,
at low rpm's (400-600 rpm), longer
than five minutes.
Long periods of idling after the engine has
reached operating temperatures
can decrease engine temperature
and cause gummed piston rings,
clogged injectors, and possible engine damage from lack of lubrication. The normal torsional vibrations
generated by the engine can also
cause transmission wear.
If an
engine must idle for an extended
period of time, it should be done at
fast idle (1,000 rpm or greater).
Cold Weather
NOTE
An idle shutdown feature, available
on PACCAR Engines, can be programmed to shut the engine down
after a period of low idle speed 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 idle shutdown system can be deactivated when the
PTO is operational; however, engine
low RPM idle periods should not exceed 5 minutes whenever possible.
NOTE
The power take off (PTO) feature,
available on PACCAR engines, can
be programmed to adjust engine idle
speed with the use of switches to
pre-programmed set points.
It is possible to operate engines in
extremely cold environments if they
are properly prepared and maintained.
Satisfactory performance of an
engine in low ambient temperature
conditions requires modification of
the engine, surrounding equipment,
operating practices and maintenance
procedures.
The correct engine coolant, lubricating
oil and fuels must be used for the cold
weather range in which the engine is
being operated. See the Maintenance

DRIVING INSTRUCTIONS
Control speed is the speed at which
the forces pushing a vehicle down a
grade are equal to the forces holding
it back.
CAUTION
NOTE
Once you have determined what the
safe speed is for your vehicle, operate the engine brakes with the transmission in the lowest gear that will
not cause the engine speed to exceed the rated engine speed. The
optimum braking power of the engine brakes is reached at rated engine speed. Correct gear selection,
therefore, is critical.
The two-position selector switch can
be used to vary braking power as road
conditions change.
The engine brake is NOT intended as

Do not drive with frequent or continuous use of the service brakes.
This can overheat the brakes and
result in excessive lining wear, increased stopping distances, possibly an accident and may lead to
personal injury. Before descending
a steep grade, shift to a lower gear,
keep the vehicle speed low, and
avoid continuous application to the
brakes. Failure to comply may result
in death, personal injury, equipment
or property damage.
NOTE
The longer or steeper the hill, the
more important it is to use your engine brakes. Make maximum use of
your engine brakes by gearing down
and letting the engine brakes do the
work.
4-20
The operation of any vehicle is difficult
to predict on slick roads. The first 10
to 15 minutes of rainfall are the most
dangerous, as road dirt and oil mixed
with rain create a very slippery surface.
If frequent use of the vehicle service
brakes is required, it is recommended
that a slower control speed be used by
selecting a lower transmission gear.
DRIVING INSTRUCTIONS
WARNING!
Do not operate the engine 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 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.
When driving on slick roads, start
with the ON/OFF switch in the “OFF”
position and the two-position selector
switch in the "LOW" position.
If your tractor is equipped with a
twin-screw rear axle, position the
power divider switch in the unlocked
position.
Remove your foot from the accelerator
pedal to make sure the vehicle will
maintain traction with the retarding
power of the engine alone.
If the vehicle drive wheels begin to skid
or if there is a fishtailing motion, do not
activate the engine brakes.
If traction is maintained using the
retarding power of the engine alone
and more braking power is required,
switch the two-position selector switch
to the "LOW" position and activate
the engine brakes by switching the
ON/OFF switch to the "ON" position.
If the vehicle’s drive wheels begin to
skid or there is a fishtailing motion,
switch the ON/OFF switch to the "OFF"
position.
If traction is maintained when the
engine brakes are activated and more
braking power is required, move the
two-position selector switch to the "HI"
position.

Maintenance Specifications
Fuel Recommendations
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
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.
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.
5-21
5
Maintenance Specifications
CAUTION
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.
If ultra-low-sulfur diesel fuel is not
used, the engine may not meet
emission regulations, and damage
may occur to the exhaust aftertreatment 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 2013 U.S. Environmental Protection Agency regulations. Failure to comply may result
in equipment or property damage.
5
NOTE
The engine has been optimized for
use with an aftertreatment system
together with ULSD fuel to meet the
2013 U.S. Environmental Protection
Agency (EPA) regulations.
5-22
Ultra-low sulfur diesel fuel is defined
as diesel fuel not exceeding 0.0015
[15 ppm] mass percent sulfur content
(ultra-low diesel fuel is also defined by
ASTM S-15). There are no acceptable
substitutes.
PACCAR recommends the use of
ASTM number 2D fuel. The use of
number 2 diesel fuel will result in
optimum engine performance.
At operating temperatures below 0°C
[32°F], acceptable performance can
be obtained by using blends of number
2D and number 1D.
The following chart lists acceptable
types of fuels for this engine.

1. Any adjustment to compensate for reduced performance with a fuel system using alternate fuel is not warrantable.
2. Winter blend fuels, such as found at commercial fuel dispensing outlets, are combinations of number 1D and number 2D diesel fuel and
are acceptable.
3. BTU Content/Degree API Gravity - Low API gravity fuels have a higher thermal energy content (BTU). As a general rule, there is a 3 to 5
percent decrease in BTU content for every 10 degree increase in API gravity, there is also a 0.7 degree API gravity increase with an
increase in fuel temperature. This decrease in energy content equates roughly to the same percentage of power loss. Use of fuels with
higher API gravity will cause higher than normal fuel consumption.
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 0°C [32°F] and a minimum of
42 for engines that are operated at
temperatures above 0°C [32°F].
NOTE
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.
PACCAR requires all permissible
fuels to have adequate fuel lubricity. This means the BOCLE number
is 3100 or greater as measured by
ASTM specification D6078, Scuffing Load Ball On Cylinder Evaluator
(SLBOCLE). Lubricity can also be
measured by ASTM, specification
D6079, ISO 12156, High Frequency
Reciprocating Rig (HFRR) in which
the fuel must have a wear scar diameter of 0.45 mm [0.02 in] or less.

Warranty and the Use of
Biodiesel Fuel
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
975 or EN 590 specifications.
The use of approved biodiesel fuel
does not affect the PACCAR engine
warranty.
5-24
Failures caused by the use of
non-approved biodiesel fuels or other
fuel additives that are of unacceptable
quality or do not meet specified
industry standards are not considered
as defects of parts or workmanship
by PACCAR and therefore will not
be covered by the PACCAR engine
warranty.
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.
The use of quality engine lubricating
oils, combined with appropriate oil
drain and filter change intervals, is a
critical factor in maintaining engine
performance and durability. Extending
the oil and filter change interval beyond
the recommendations will decrease
engine life due to factors such as
corrosion, deposits, and wear. Refer
to “Oil Drain Intervals” on page 5-11
to determine which oil drain interval to
use for an application.
API: American Petroleum Institute
CES: Cummins Engineering
Standard
PACCAR allows, for midrange
applications, the use of lubricating
oils that meet or exceed CES 20078
or CES 20081 with no change in
oil drain interval. But, if a non-low
ash lubricating oil meeting the
Cummins Engineering Standard
(CES) classification CES 20078 is
used, the service interval(s) for the
aftertreatment system will be reduced.
NOTE
It is the owners responsibility to
correctly follow lubricating oil recommendations. If recommendations
are ignored, the engine warranty
could be affected.

To determine if the lubricating oil meets
CES 20078 or CES 20081, review the
label on the back of the lubricating oil
bottle for the CES 20078 or CES 20081
reference. If acquiring the lubricating
oil in bulk, contact the supplier for
the lubricating oil specifications and
confirm that the oil meets CES 20078
or CES 20081.

NOTE
A lubricating oil that meets the

may not meet the CES 20081 requirement. Always make sure the
lubricating oil used meets the CES

PACCAR recommends the use of
high-quality SAE 15W-40 heavy-duty
engine oil.
API CH-4/SJ
The primary PACCAR
recommendation is for the use of
15W- 40 multigrade lubricating oil
for normal operation at ambient
temperatures above -15°C [5°F].
The use of multigrade oil reduces
deposit formation, improves engine
cranking in low temperature conditions
and increases engine durability by
maintaining lubrication during high
temperature operating conditions.
Since multigrade oils have been shown
to provide approximately 30 percent
lower oil consumption compared with

monograde oils, it is important to
use multigrade oils to be certain the
engine will meet applicable emissions
requirements.
Use of "synthetic engine oils" (those
made with API group 3 or group 4
base stocks) is permitted subject to
the same performance and viscosity
limitations of petroleum (mineral)
based engine oils. The same oil
change intervals must be applied
to synthetic oils that are applied to
petroleum (mineral) based engine oils.

While the preferred viscosity grade is
15W-40, lower viscosity multigrade oils
can be used in colder climates. See
the accompanying chart. Any viscosity
grade lower than 15W-40 must still
meet CES 20081.
Synthetic engine oils, API Group
III and Group IV basestocks, are
recommended for use in PACCAR
5-28
engines operating in ambient
temperature conditions consistently
below - 25°C [-13°F]. Synthetic 0W-30
oils that meet the requirements of API
Group III or Group IV basestocks,
can be used in operations where the
ambient temperature never exceeds
0°C [32°F]. Multiviscosity oils rated
0W-30 do not offer the same level of
protection against fuel dilution as do
higher multigrade oils. Higher cylinder
wear can be experienced when using
0W-30 oils in high-load situations.
As these oils have directionally thinner
oil films than 15W-40 oils, top-quality
Fleetguard® filters must be used
above 20°C [70°F]. Some oil suppliers
might claim better fuel economy for
these oils. PACCAR can neither
approve nor disapprove any product
not manufactured by PACCAR. These
claims are between the customer and
oil supplier. Obtain a commitment from
the oil supplier that the oil will give
satisfactory performance in PACCAR
engines or do not use the oil.
Maintenance Specifications
New Engine Break-In Oils
Aftermarket Oil Additive Usage
CAUTION
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.
CAUTION
A sulfated ash limit of 1.85 percent
has been placed on all engine lubricating oils recommended for use in
PACCAR engines. Higher ash oils
can cause valve and/or piston damage and lead to excessive oil consumption. Failure to comply may result in equipment damage.
The use of a synthetic-base oil does
not justify extended oil change intervals. Extended oil change intervals
can decrease engine life due to factors such as corrosion, deposits, and
wear. Failure to comply may result in
equipment damage.
Additional information regarding
lubricating oil availability throughout
the world is available in the EMA
Lubricating Oils Data Book for
Heavy-Duty Automotive and Industrial
Engines. The data book can be
ordered from: Engine Manufacturers
Association, Two North LaSalle Street,
Chicago, IL 60602; (312) 827-8733,
(www.enginemanufacturers.org).
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 furnished oils
meet performance characteristics
that conform to the lubricant industry
standards. Aftermarket lubricating oil
additives are not necessary to enhance
engine oil performance and in some
cases can reduce the furnished oil's
capability to protect the engine.

Coolant Recommendations
and Specifications
Fully Formulated
Coolant/Antifreeze
5
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].
Good-quality water is important
for cooling system performance.
Excessive levels of calcium and
5-30
magnesium contribute to scaling
problems, and excessive levels of
chlorides and sulfates cause cooling
system corrosion.
PACCAR vehicle engine-cooling
systems are filled with fully formulated
extended-life coolant (ELC).
Water Quality
Calcuim Magnesium Maximum 170 ppm
as (CaCO3 + MgCO3)
(hardness)
Chloride
40 ppm as (Cl)
Sulfur
100 ppm as (SO4)
PACCAR recommends the use of fully
formulated extended life coolant that
meets the requirements of Cummins
Engineering Standard (C.E. S.) 14603
for top off and service.
Fully formulated antifreeze must be
mixed with good quality water at a
50/50 ratio (40- to 60-percent working
range). A 50/50 mixture of antifreeze
and water gives a -36°C [-33°F]
freezing point and a 108°C [226°F]
boiling point, which is adequate for
locations in North America. The actual
lowest freezing point of ethylene glycol
antifreeze is at 68 percent. Using
higher concentrations of antifreeze will
raise the freezing point of the solution
and increase the possibility of a silica
gel problem.
Maintenance Specifications
If the replacement coolant is Chevron
Texaco, Shell Rotella or their private
label counterparts which do not meet
the elastomer compatibility section
of CES 14603, the coolant must be
treated by adding 0.24 liter [8oz]
of liquid silicate fluid for every 45
liters [12 gal] of total coolant system
volume. It is critical to not over
treat the coolant with silicate fluid. If
overtreatment is suspected, drain the
cooling system and discard the filter.
Clean the cooling system immediately.
Symptoms of silicate over-treatment
can be thickened coolant in the lower
radiator tank, water pump seal leakage
soon after silicate addition, reduced
heater output and/or elevated engine
temperatures.

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.
5-32
A refractometer must be used to
measure the freezing point of the
coolant accurately. Use Fleetguard®
refractometer, Part Number C2800.

Products Warranted
United States includes American
Samoa, the Commonwealth of Northern
Mariana Islands, Guam, Puerto Rico,
and the U.S. Virgin Islands.
PACCAR warrants to the first
purchaser and each subsequent
purchaser that the Engine is designed,
built and equipped so as to conform
at the time of sale by PACCAR with
all U.S. Federal emission regulations
applicable at the time of manufacture
and that it is free from defects in
material or factory workmanship which
would cause it not to meet these
regulations within the longer of the
following periods: (A) Five years or
100,000 miles [160,935 kilometers] of
operation, whichever occurs first, as
measured from the date of delivery of
the Engine to the first purchaser or (B)
The Base Engine Warranty.
If the vehicle in which the Engine
is installed is registered in the state
of California, a separate California

Warranty
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 or an authorized Cummins
Distributor. 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 Cummins
Distributor, 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
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
non-Engine repairs, downtime
expenses, cargo damage, fines, all
applicable taxes, all business costs

On-Highway
Products Warranted
This Emission Control System
Warranty applies to diesel engines
(hereafter, engines) certified with
the California Air Resources Board
beginning with the year 2009,
marketed by PACCAR, and registered
in California for use in on-highway
applications.
Warranty
Your Warranty Rights and
Obligations
The California Air Resources Board
and PACCAR Inc are pleased to
explain the emission control system
warranty on your 2009 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 warranty
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.
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
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 [160,935
km] or 3,000 hours of engine operation,
whichever first occurs from the date
of delivery of the engine to the first

the performance of all scheduled
maintenance.
6-20
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.

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.
A warranted part which is scheduled for
replacement as required maintenance
is warranted up to the first scheduled
replacement point.
Warranty
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.

Replacement Parts
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 or an authorized Cummins
Distributor. 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.
The owner may elect to have
maintenance, replacement or repair of
the emission control parts performed
by a facility other than a PACCAR
authorized dealer or an authorized
Cummins Distributor and may elect
to use parts other than new genuine
approved rebuilt parts and assemblies
for such maintenance, replacement
or repair; however, the cost of such
service or parts and subsequent
failures resulting from such service or
parts will not be covered under this
emission control system warranty,
except for Emergency Repairs as
described below.

Warranty
PACCAR Responsibilities
Emergency Repairs
The warranty coverage begins when
the engine is delivered to the first
purchaser. Repairs and service will be
performed by any authorized PACCAR
Engine, dealer or an authorized
Cummins Distributor using new or
genuine approved rebuilt parts and
assemblies. PACCAR will repair
any of the emission control parts
found by PACCAR to be defective
without charge for parts 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
or an authorized Cummins Distributor
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 manufacturer's suggested retail
price for all warranted parts replaced
and labor charges based on the
manufacturer's recommended time
allowance for the warranty repair and
the geographically appropriate hourly
labor rate.
6
6-24
Replaced parts and paid invoices
must be presented at an authorized
PACCAR Engine dealer or authorized
Cummins Distributor as a condition
of reimbursement for emergency
repairs not performed by an authorized
PACCAR Engine dealer or an
authorized Cummins Distributor.
