ENGINE OPERATION - Safety - Introduction
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.
• Always use wheel chocks or proper
jack stands to support the vehicle or
vehicle components before
performing any service work. DO
NOT work on anything that is
supported only by lifting jacks or a
hoist. Before resting a vehicle on
jack stands, be sure the stands are
rated for the load you will be placing
on them.
Y53-1166-1D1 (11/2016)
• Before removing or disconnecting
any lines, fittings, or related items,
relieve all pressure in the air, oil,
fuel, and cooling systems. Remain
alert for possible pressure when
disconnecting any device from a
system that contains pressure. High
pressure oil or fuel can cause death
or personal injury.
• Always wear protective clothing
when working on any refrigerant
lines and make sure that the
workplace is well ventilated.
Inhalation of fumes can cause death
or personal injury. To protect the
environment, liquid refrigerant
systems must be properly emptied
and filled using equipment that
prevents the release of refrigerant
gas. Federal law requires capturing
and recycling refrigerant.
• When moving or lifting any heavy
equipment or parts, make sure to
use proper techniques and
assistance. Ensure all lifting devices
such as chains, hooks, or slings are
in good condition and are of the
correct load capacity. Make sure all
lifting devices are positioned
correctly.
• Corrosion inhibitors and lubricating
oils may contain alkali. DO NOT get
the substance in eyes and avoid
prolonged or repeated contact with
skin. DO NOT swallow. If ingested,
seek immediate medical attention.
DO NOT induce vomiting. In case of
contact, immediately wash skin with
soap and water. In case of harmful

determined that used engine oil can
be carcinogenic and can cause
reproductive toxicity. Avoid
inhalation of vapors, ingestion, and
prolonged contact with used engine
oil.
• DO NOT connect the jumper
starting or battery charging cables
to any ignition or governor control
wiring. This can cause electrical
damage to the ignition or governor.
• Coolant is toxic. If not reused,
dispose of coolant in accordance
with local environmental regulations.
• California Proposition 65 Warning Diesel engine exhaust and some of
its constituents are known to the
State of California to cause cancer,
birth defects, and other reproductive
harm.
• The catalyst substrate located in the
Diesel Particulate Filter (DPF)
contains vanadium pentoxide, which
has been determined by the State of
California to cause cancer. Always
wear protective clothing and eye
protection when handling the
catalyst assembly. Dispose of the
catalyst in accordance with local
regulations. If catalyst material gets
into the eyes, immediately flood
eyes with water for a minimum of 15
minutes. Avoid prolonged contact

persists, contact an authorized
PACCAR engine dealer as soon as
possible.
Check Engine Lamp Turns On
The lamp will also illuminate when a DPF
regeneration or addition of diesel exhaust
fluid (DEF) is required. Another function of
the check engine lamp is to warn the
operator of an impending idle shutdown.
When the idle shutdown timer is 30
seconds from expiring, the ECM begins
flashing the check engine warning lamp
once per second. When the timer expires,
the ECM will turn off the warning lamp and
shut down the engine.
Engine is Overheating
The cooling system may overheat if the
coolant level is below normal or if there is
sudden loss of coolant. Follow these steps
if the engine is overheating.
What to do if the check engine lamp turns
on.

not be considered an emergency.
Y53-1166-1D1 (11/2016)
ENGINE OPERATION - Emergency - What To Do If
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/ highload driving.
• Debris blocking air flow through
the cooling module (radiator).
If the engine coolant temperature warning
lamp comes on and the audible alarm
sounds showing an overheat condition, or
Y53-1166-1D1 (11/2016)

1. Reduce engine speed, or stop.
When stopped, place the
transmission in neutral (N) and set
the parking brake. Keep the engine
running. See the vehicle operator's
manual for instructions on
transmission shifting and parking
brake information.
WARNING!
To reduce the chance of personal injury, vehicle damage
and/or death from overheated
engines, which can result in a
fire, never leave the engine
idling without an alert driver
present. If the engine should
overheat, as indicated by the
13

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.
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.
NOTE
Keep the engine running at idle
speed unless a warning icon
turns on and requires an engine
to be shut off.
14
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.
2. Check to ensure the Oil Pressure
Gauge reads normal.
3. Make sure the engine fan is turning
by switching the Engine Fan Switch
from AUTO to MAN (Manual).
4. Increase the engine speed to about
one-half of full operating speed, or
1,100 to 1,200 rpm, maximum for 2
or 3 minutes.
5. Return the engine speed to normal
idle. Monitor the engine
temperature. After the temperature
returns to normal, allow the engine
to idle 3 to 5 minutes before shutting
it off. This allows the engine to cool
gradually and uniformly.
6. If overheating came from severe
operating conditions, the
temperature should have cooled by
this time. If it has not, stop the
engine and let it cool before
checking to see if the coolant is low.
7. Be sure the vehicle is parked on
level ground or the readings may be

Engine Braking System
Information on using the engine braking
system.
An engine compression brake is standard
on the MX-11 engines. Optionally, this
Y53-1166-1D1 (11/2016)
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. There
may not be enough weight on the rear
axle to provide traction. 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.
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.

WARNING!
The service brakes must be used in an
emergency. The engine compression
brake alone might not stop the vehicle
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 back pressure 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.
warm the engine before activating the
engine brakes.
NOTE
If your vehicle is equipped with antilock 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.
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.
Compression Brake
CAUTION
DO NOT operate the engine brake until the engine oil temperature is above
86°F (30°C). Operation below 86°F
(30°C) could cause severe damage to
the engine. Idle the engine four minutes at approximately 1000 RPM to

the brake is ON (ready to slow the vehicle
down) or OFF (no braking action).
1. Do not use the engine compression
brake to slow the vehicle down
when you are bobtailing or pulling
an empty trailer.
2. Make sure the brake is OFF before
starting the engine.
3. After the engine is started, warmed
up and you are ready to get under
way, turn the engine compression
brake switch ON for added braking
effect.
NOTE
If your vehicle is equipped with
the Eaton Vorad® system, operation of the compression brake
may be automatically activated.

to the engine and aftertreatment system.
If an engine must idle for an extended
period of time, it should be done at a fast
idle (1,000 RPM maximum) at coolant
temperatures below 150°F (70°C).
3. For coolant temperatures below
150°F (70°C), use a low gear and
drive at moderate engine speed
until the engine coolant has reached
operating temperature. Do not let
the engine idle longer than
necessary.
Refer to the vehicle operator's
manual instructions for any
additional cold weather starting
procedures.
2. 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.

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
combustion chamber.
• Sticking of the valves
in the cylinder head.
• Reduced performance.
• Damage to aftertreatment components.
Starting Procedure After Extended
Shutdown or Oil Change
Guideline on starting the engine after
prolonged shutdown or oil change.
After extended shutdown or an oil change
follow the Normal Starting Procedure on

Operating the Engine
After the engine starts:
Monitor the oil pressure and coolant
temperature gauges frequently. Refer to
Engine Oil Specifications on page 41 and
Engine Coolant Specifications on page
47 for recommended operating pressures
and temperatures. Shut off the engine if
any pressure or temperature does NOT
meet the specifications.
Engine Operating Range
Information on operating the engine at
proper RPM.
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.
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. See Engine Specifications for maximum engine speed.
Failure to comply may result in equipment or property damage.
NOTE
For applications with high idle-time, to
help reduce soot loading in the aftertreatment system, avoid long periods
of idling. If idling is required, increase
idle-speed using the cruise control
function.

Engine Shutdown
Before stopping the engine follow these
precautions.
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.
Electromagnetic Interference
Information on electromagnetic
interference (EMI).
If not installed correctly, some vehicle
accessories (CB radios, mobile
24
transmitters, etc.) can generate and use
radio frequency energy that may cause
electromagnetic interference (EMI)
between the accessory and the
electronically 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.
System EMI Susceptibility
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.
System EMI Radiation Levels
If any interference condition is noticed,
follow these suggestions to reduce the
amount of EMI:
1. Locate the accessory receiving
antenna further away.
2. Check with the accessory supplier
representative in your area to:
• Accurately calibrate the
accessory for proper frequency,
power output, and sensitivity.
• 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.
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.

Slow Down Around Curves
Never exceed governed engine speed
because engine damage can occur.
Operating engine beyond the governed speed causes additional strain
on valve train and internal engine components. Operate the engine within
governed engine speed.
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.

Engine Maintenance
Introduction and important maintenance
requirements.
PACCAR recommends that the engine be
maintained according to the maintenance
schedule in this section.
If the engine is operating in ambient
temperatures below 0°F (-18°C) or above
100°F (38°C), perform maintenance at
shorter intervals. Shorter maintenance
intervals are also required if the engine is
operated in a dusty environment or if
frequent stops are made.
Some of these maintenance procedures
require special tools or must be completed
by qualified personnel. Contact your local
PACCAR authorized repair location for
detailed information.
If your engine is equipped with a
component or accessory not manufactured
by PACCAR Inc, refer to the component
Y53-1166-1D1 (11/2016)
manufacturer's maintenance
recommendations.
WARNING!
Never idle your vehicle for prolonged
periods of time if you sense that exhaust fumes are entering the cab. Investigate the cause of the fumes and
correct it as soon as possible. If the
vehicle must be driven under these
conditions,drive only with the windows
open. Failure to repair the source of
the exhaust fumes may result in death,
personal injury, equipment or property
damage.
WARNING!
Exhaust fumes from the engine contain carbon monoxide, a colorless and
odorless gas. Do not breathe the engine exhaust gas. A poorly maintained,
damaged or corroded exhaust system
can allow carbon monoxide to enter
the cab. Entry of carbon monoxide into
the cab is also possible from other vehicles nearby. Failure to properly maintain your vehicle could cause carbon
monoxide to enter the cab, resulting in
death or personal injury.

PACCAR recommends the use of highquality SAE 10W-30 API CK-4 heavy-duty
engine oil.
The primary PACCAR recommendation is
for the use of 10W-30 multigrade
lubricating oil for normal operation at
ambient temperatures above 5°F (-15°C).
For ambient temperatures below 5°F
(-15°C) SAE 5W-30 may be used, provided
it meets API CK-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.

Cooling System
Maintenance
Y53-1166-1D1 (11/2016)
Your engine’s cooling system is standard
with Nitrited forumulated Extended Life
Coolant (ELC) that meets or exceeds
ASTM D 6210 requirements. Nitrite-Free
Extended Life Antifreeze/Coolant can be
used if it meets ASTM D6210 and
Cummins CES 14439. ELC consists of a
mixture of ethylene glycol, water, and
organic acid technology chemical
inhibitors. ELC prevents corrosion and
scale formation as well as provides
freezing and boiling point protection.
WARNING!
Coolant is toxic. DO NOT get the fluid
in eyes. If contact occurs, flood eyes
with large amounts of water for 15 minutes. Avoid prolonged or repeated
contact with skin. In case of contact,
immediately wash skin with soap and
water. DO NOT take internally. If swallowed, seek immediate medical attention. DO NOT induce vomiting. Failure
to comply may result in death, personal injury, equipment or property damage.

The engine cooling system has very
specific maintenance and inspection
requirements. Failure to follow requirements can damage the engine. Engine
damage can include but is not limited
to freezing, boiling, corrosion, pitted
cylinder liners. This information is
found in the engine manufacturers
owner’s manual. It is the owner’s responsibility to follow all requirements
listed in the engine manufacturers

NOTE
Coolant is harmful to the environment.
Unused coolant must be stored as a
toxic hazardous material in leakproof
containers. Used coolant must be
processed as industrial chemical
waste. Please follow HAZMAT guidelines with both used and unused coolants.
44
Check the level of freeze/boilover
protection, which is determined by the ELC
concentration. Use a glycol refractometer
to determine glycol level. Add ELC to
obtain the ELC/water ratio required to
provide the protection you need. A 50/50
mix of ELC and water is adequate for most
applications. For extremely cold operating
conditions, the ratio can be adjusted to a
higher concentration of ELC.
NOTE
mechanical problems, submit a coolant
sample for analysis. Improper maintenance
may cause coolant degradation and could
result in damage to the cooling system and
engine components. Consult your dealer or
the ELC manufacturer’s representative for
recommended ELC test kits, test strips,
and laboratory sample procedures.
Coolant Extender
Add ELC extender if necessary according
to the concentration level required. DO
NOT add coolant extender to nitrite-free
coolant.
Maximum recommended ELC concentration is 60% ELC and 40% water by
volume (a 60/40 coolant mixture). The

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.

ENGINE MAINTENANCE - Fuel Recommendations
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
Unapproved fuel can reduce economy
or possibly damage fuel system components. Unapproved 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.
Y53-1166-1D1 (11/2016)
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.
CAUTION
If ultra-low-sulfur diesel (ULSD) 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. ULSD fuel is required for correct operation of the aftertreatment. The engine has been optimized for use with an aftertreatment
system together with ULSD fuel to
meet the 2013 U.S. Environmental
Protection Agency regulations. Failure
to comply may result in equipment or
property damage.
2
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 32ºF
(0ºC) and a minimum of 42 for engines
that are operated at temperatures
above 32ºF (0ºC).
Using diesel fuel with a lower-thanrecommended cetane number can cause
hard starting instability, and excessive
white smoke. To maintain satisfactory
operation at low ambient temperatures, it is
49
ENGINE MAINTENANCE - Warranty and the Use of Biodiesel Fuel
important to specify diesel fuel of the
correct cetane number.
2
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.
The use of Ultra-low-sulfer-diesel (ULSD)
fuel is required for this engine in order to
meet emission regulations and to prevent
damage to the engine and exhaust system.
The use of other grades of diesel fuels
other than 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.
Warranty and the Use of
Biodiesel Fuel
Biodiesel information and warranty
precautions.
50
PACCAR Inc. approves the use of
biodiesel fuel blends from 6 to 20 percent
by volume in diesel fuel providing that the
following conditions are met:
• 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 the ASTM Standard
D975 (up to B5 blend) or D7467 (B6
to B20 blend).
• The engine oil and oil filter are
changed per the modified schedule.
See the Engine Preventative
Maintenance Schedule.
• The fuel filter is changed every
25,000 miles/40,000 km.
The use of approved biodiesel fuel does
not affect the PACCAR engine warranty.
Failures caused by the use of nonapproved 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.
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.
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.
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.

Maintenance Procedures
Engine Oil Level
This procedure should be followed as part
of routine maintenance checks.
1. Twist the dipstick handle to unlock
it, then pull the dipstick out of the
holder.
2
How to check engine oil level
To check engine oil level, park vehicle on
level ground and wait 15 minutes after
shutting off engine. After the engine is shut
off it will take at least 15 minutes for all the
engine oil to return to the sump.
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.
Make sure that the vehicle suspension is
sitting flat, both lengthwise and crosswise.
Check this carefully on a vehicle with air
suspension.
2. Wipe the dipstick clean with a lintfree cloth.
3. Reinsert the dipstick into the holder.
4. Remove the dipstick from the holder
and check the oil level. The oil level
should always be between the two
marks on the dipstick.
5. Reinstall the dipstick and twist to
lock it in place.
Engine coolant should be at or above the
operating temperature of 180°F (82°C).

California Emissions Control
System Warranty
Emissions coverage for on-highway
applications in the State of California.
This emission control system warranty
applies to diesel engines (hereafter,
engines) certified with the California Air
Resources Board beginning with the year
2013, marketed by PACCAR, and
registered in California for use in onhighway applications.
Your Warranty Rights and
Obligations
The California Air Resources Board and
PACCAR are pleased to explain the
Y53-1166-1D1 (11/2016)
emission control system warranty on your
2016 – 2017 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.
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 mi (160,000) km or 3,000
hours of engine operation, whichever first
occurs from the date of delivery of the
engine to the first purchaser or first lessee.
Where a warrantable condition exists,
PACCAR will repair your engine at no cost
to you including diagnosis, parts and labor.
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

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, the 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.
The 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.
The owner is responsible for downtime
expenses, cargo damage, fines, all
applicable taxes, all business costs, and

Replacement Parts
State of California emissions statement on
replacement parts.
PACCAR recommends that any service
parts used for maintenance, repair or
replacement of emission control systems
be new or genuine PACCAR 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.
The owner may elect to have maintenance,
replacement or repair of the emission
control parts performed by a facility other
than an authorized PACCAR engine dealer
and may elect to use parts other than new
or 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 on page 92.”
PACCAR Responsibilities
State of California emissions statement on
PACCAR's responsibility.

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).
Emergency Repairs
State of California emissions statement on
emergency repairs.
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

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.
92
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 .
Warranty Limitations
State of California emissions statement on
warranty limitations.
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

operation without adequate coolants or
lubricants; overfueling; overspeeding; lack
of maintenance of cooling, lubricating or
intake systems; improper storage, starting,
warm-up, run-in or shutdown practices;
failure to perform regeneration in a timely
manner; unauthorized modifications to 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 nonwarrantable conditions is not warrantable.
PACCAR is not responsible for failures
resulting from improper repair or the use of
parts which are not genuine PACCAR
approved parts.
PACCAR is not responsible for the material
and labor costs of emission control parts
and assemblies replaced during Scheduled
Maintenance of the engine as specified in
