situation should not be considered an
emergency.
Engine is Overheating
NOTE
CAUTION
The system may also temporarily
overheat during severe operating
conditions such as:
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.

•
Check to ensure that the oil
pressure gauge reads normal.
•
Increase the engine speed to
1,100 to 1,200 RPM maximum for
two to three minutes.
•
Monitor the engine temperature.
After the temperature returns
to normal, allow the engine to
idle three to five minutes before
shutting it off. This allows the
engine to cool gradually and
uniformly.
•
If the overheating came from
severe operating conditions, the
temperature should have cooled
by this time.
2-6
•
Be sure the vehicle is parked on
level ground or the readings may
be incorrect. 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.
Y53-1183-1B1
WARNING!
Removing the fill cap on a hot engine can cause scalding coolant
to spray out and burn you badly.
If the engine has been in operation within the previous 30 minutes,
be very careful in removing the fill
cap. Protect face, hands, and arms
against escaping fluid and steam
by covering the cap with a large,
thick rag. DO NOT try to remove
it until the surge tank cools down
or if you see any steam or coolant
escaping. In any situation, remove
the cap very slowly and carefully.
Be ready to back off if any steam
or coolant begins to escape. See
the vehicle operator's manual for
instructions on checking and filling
the cooling module surge tank.
(12/2014)
WHAT TO DO IF...
CAUTION
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. Failure
to comply may result in equipment
or property damage.
(12/2014)
CAUTION
If the truck is equipped with power
take off (PTO) equipment, the engine shutdown system can be deactivated when the PTO is operational; however, engine idle periods should not exceed five minutes whenever possible. 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 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 housingis created
through positioning of the sliding
nozzle (1) located internally to the
turbocharger. the position of the sliding
nozzle is controlled by the engine
electronic control module (ECM). This
option may not be available on your
vehicle.
3-8
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.
Y53-1183-1B1
WARNING!
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.
(12/2014)
OPERATING INSTRUCTIONS
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.
(12/2014)
NOTE
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.
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.
Y53-1183-1B1
WARNING!
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.
NOTE
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
CAUTION
NOTE
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.
The engine (VGT) exhaust brake
is designed to assist the vehicle's
service brakes when slowing the
vehicle to a stop.

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.

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.

OPERATING INSTRUCTIONS
Engine Shutdown
Continuous operation with engine
coolant temperature above or below
the engine coolant temperature
specifications listed in “Cooling
System” on page 5-14 can damage
the engine.
Before Stopping the Engine
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 four
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.
(12/2014)
Y53-1183-1B1
NOTE
For engines equipped with an electronic control module (ECM) ensure the key switch is turned OFF
for a minimum of 70 seconds prior
to disconnecting the continuous
(unswitched) battery power supply.
If the unswitched battery power
supply is disconnected in less than
70 seconds after the key switch
is turned OFF, active fault codes
and incorrect ECM information can
occur.
Turn the ignition switch to the OFF

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.

Tips for Operation on Level
and Dry Pavement
WARNING!
DO NOT use the engine brake
when operating on road surfaces
with poor traction (such as wet, icy,
or snow covered roads or gravel).
Retarders 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.

DO NOT use an engine 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 engine brake is switched
“OFF” when bobtailing or with an
unloaded trailer. Failure to comply may result in death, personal
injury, equipment or property damage.
To reduce vehicle speed, put the
engine brake “ON/OFF” switch in the
“ON” position. Remove your foot from
the accelerator pedal and clutch pedal.
The engine brakes will immediately
begin to operate, slowing the vehicle.
For operation on dry and relatively flat
surfaces, when greater retarding power
is not required, put the two-position
selector switch in the “LOW” position.
For operation on dry pavement when
maximum retarding power is required,
put the two-position selector switch in
the “HI” position.
Tips for Operation on Grades
with Dry Pavement
WARNING!
The engine 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 engine brake to stop the vehicle in an emergency could cause
an accident and lead to personal
injury. The engine 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.
“Control speed” is the speed at which
the forces pushing a vehicle down a

Y53-1183-1B1
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.
Vehicle service brakes must be used
when additional braking power is

The engine brake is NOT intended as
the primary brake for the vehicle, nor
is it an emergency brake. The engine
brake only helps the service brakes by
using pressure to slow the drivetrain.
Use the service brakes for quick stops.
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.
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.
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

Tips for Operation on Slick
Roads
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.
WARNING!
To reduce the possibility of personal injury or property damage,
always allow for extra distance
between your vehicle and other
objects when using the service
brakes or engine brakes on slick
roads.
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.
(12/2014)
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.

maintain traction with the retarding
power of the engine alone.
4-17
OPERATING INSTRUCTIONS
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.
4
Again, if the vehicle has lost traction or
if there is a fishtailing motion, switch
the “ON/OFF” switch to the “OFF”
position. DO NOT attempt to use the
engine brakes in the “HI” 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

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
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.

5-17
MAINTENANCE SPECIFICATIONS
CAUTION
Unapproved 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
5-18
Y53-1183-1B1
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 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.
(12/2014)
MAINTENANCE SPECIFICATIONS
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).
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 32°F
(0°C), acceptable performance can be
(12/2014)
obtained by using blends of number
2D and number 1D.
Using diesel fuel with a
lower-than-recommended cetane
number can cause hard starting, poor
idle and excessive white smoke. To
maintain satisfactory operation at low
ambient temperatures, it is important
to specify diesel fuel of the correct
cetane number.
ULSD 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 DEF
or by water, dirt or other containments
in the fuel or DEF.
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.

Any adjustment to compensate for reduced performance with a fuel system using alternate fuel is not warrantable.
Winter blend fuels, such as found at commercial fuel dispensing outlets, are combinations of number 1D and number 2D diesel fuel
and are acceptable.
BTU Content/Degree API Gravity - Low API gravity fuels have a higher thermal energy content (BTU). As a general rule, there is a three to
five 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.

Recommendation to Avoid Fuel
Gelling
•
Use appropriate fuel grade/blend
for conditions.
•
Specify vehicle with proper cold
weather equipment (fuel filter, line
and tank heaters).
PACCAR does not recommend the
use of fuel additives, however, should
a customer decide there is a need for
temporary use of a winter fuel additive,
PACCAR offers the following guidance:
•
Use an industry known, high
quality product (EPA approved).
•
Only use the additive for the
minimum time needed.
•
Follow additive manufacturer's
instructions exactly.

the following conditions are meet:
•
The biodiesel used in the blend
meets ASTM Standard D6751 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 the ASTM Standard
D975 (up to B5 blend) or D7467
(B6 to B20 blend).
•
The engine oil and oil filter are
changed at 40,000 miles/64,000
km (or six months).
•
The fuel filter is changed every
25,000 miles/40,000 km.

5-22
The use of approved biodiesel fuel
does not affect the PACCAR engine
warranty. 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.
In particular, operators should be
aware that biodiesel blends are
more prone to cold flow (gelling) and
filter plugging issues compared to
conventional diesel fuel. If vehicles
are expected to be operated in
temperatures below freezing, care
should be taken to ensure that both the
biodiesel fuel used and the appropriate
vehicle fuel system accessory heaters
are utilized.
PACCAR recommends that customers
intending to use biodiesel blends
become familiar with the additional
handling considerations of these fuels
such as ageing, metal compatibility
and tendency to absorb water. Please
reference the fuel supplier’s technical
information or industry guidelines such
as the American Trucking Association
Truck Maintenance Council document
RP 357.
Operators should also be aware that
biodiesel energy content (by volume)
is lower than diesel which can reduce
fuel economy by up to two percent.

PACCAR recommends the use of
high-quality SAE 10W30 API CJ-4
heavy-duty engine oil.
biodiesel blended fuel is not used as
fuel for the engine. Using a multigrade
oil helps improve engine cranking in
low-temperature conditions, reduces

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.
The primary PACCAR
recommendation is for the use of
10W30 multigrade lubricating oil
for normal operation at ambient
temperatures above 5°F (-15°C).
For ambient temperatures below

Aftermarket Oil Additive Usage
CAUTION
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).
(12/2014)
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.

Inspection of the Engine Oil
Level
NOTE
It takes approximately 15 minutes
for all the oil to run into the sump
when the engine is ‘warm.’ If the
level is checked immediately after
switching off the engine, the dipstick will show a low oil level.
After the engine is shut off it will take
at least 15 minutes for all the engine
oil to return to the sump. If the level is
checked immediately after switching
off the engine, the dipstick will show
a low oil level.
1.
Engine coolant should be at or
above the operating temperature
of 180°F (82°C).
2.
Make sure that the vehicle
suspension is sitting flat, both
lengthwise and crosswise. Check

4.
Wipe the dipstick clean with a
lint-free cloth.
5.
Reinsert the dipstick into the
holder.
6.
Remove the dipstick from the
holder and check the oil level. The
oil level should always be between
the two marks on the dipstick.
7.
Reinstall the dipstick and twist to
lock it in place.
2. Low oil level
On the engine oil dipstick, the difference between the low oil level
mark (2) and high oil level mark (1)
is two US quarts (1.9 liters).

If checking the engine oil just
after stopping the engine, wait 15
minutes for the oil to drain back
into the oil pan before checking
the fluid level.
2.
Top up with oil, if necessary, via
the filler opening. Use the correct
grade in the correct quantity.

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).
Good-quality water is important
for cooling system performance.
Excessive levels of calcium and
magnesium contribute to scaling
problems, and excessive levels of
(12/2014)
chlorides and sulfates cause cooling
system corrosion.
Water Quality
Calcuim
Magnesium
(hardness)
Maximum 170
ppm as (CaCO3 +

Chloride

Sulfur
100 ppm as (SO4)
PACCAR vehicle engine-cooling
systems are filled with fully formulated
ELC.
PACCAR recommends the use of
fully formulated ELC that meets the
requirements of CES 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 -33°F (-36°C)
freezing point and a 226°F (108°C)
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,
increase the likelihood of overheating
and increase the possibility of a silica
gel problem.

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 8oz (0.24
liter) of liquid silicate fluid for every
12 gallons (45 liters) 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:
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, depending on operating
conditions.
(12/2014)
A refractometer must be used to
measure the freezing point of the
coolant accurately. Use Fleetguard®
refractometer, Part Number C2800.

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 first
lessee; (B) The base engine warranty.
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

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.
