ACCESSORY DRIVE BELT INSPECTION
When inspecting accessory drive belts, small
cracks that run across the ribbed surface of a belt
from rib to rib, are considered normal. These are
not a reason to replace belt. However, cracks
running along a rib (not across) are not normal. Any
belt with cracks running along a rib must be
replaced. Also, have the belt replaced if it has
excessive wear, frayed cords, or severe glazing.
Accessory Belt (Serpentine Belt)

Conditions that would require replacement:
Rib chunking (one or more ribs has separated
from belt body)
Rib or belt wear
Longitudinal belt cracking
(cracks between two ribs)
Belt slips
“Groove jumping" (belt does not maintain
correct position on pulley)
Belt broken
NOTE:Identify and correct problem before new belt is
installed
Noise (objectionable squeal, squeak, or rumble
is heard or felt while drive belt is in operation).
Some conditions can be caused by a faulty
component such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
use of special tools; we recommend having your
vehicle serviced at an authorized dealer.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner
should be checked and serviced by an authorized
dealer at the start of each warm season. This
service should include cleaning of the condenser
fins and a performance test. Drive belt tension
should also be checked at this time.
WARNING!
Do not attempt to inspect an accessory drive
belt with vehicle running.
When working near the radiator cooling fan,
disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition mode. You could be
injured by the moving fan blades.
You can be badly injured working on or around
a motor vehicle. Only do service work for which
you have the knowledge and the proper equip -
ment. If you have any doubt about your ability
to perform a service job, take your vehicle to a
competent mechanic.
WARNING!
Use only refrigerants and compressor lubri -
cants approved by the manufacturer for your
air conditioning system. Some unapproved
refrigerants are flammable and can explode,
injuring you. Other unapproved refrigerants or
lubricants can cause the system to fail,
requiring costly repairs. Refer to Warranty
Information located online, for further
warranty information.8

286SERVICING AND MAINTENANCE
Under normal operating conditions, the catalytic
converter will not require maintenance. However, it
is important to keep the engine properly tuned to
ensure proper catalyst operation and prevent
possible catalyst damage.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a scorching odor
may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, including a
tune-up to the manufacturer specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter
damage:
Do not interrupt the ignition when the transmis -
sion is in gear and the vehicle is in motion.
Do not try to start the vehicle by pushing or
towing the vehicle.
Do not idle the engine with any ignition compo -
nents disconnected or removed, such as when
diagnostic testing, or for prolonged periods
during very rough idle or malfunctioning oper -
ating conditions.
COOLING SYSTEM
Engine Coolant Checks
Check the engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine coolant is
dirty, the system should be drained, flushed, and
refilled with fresh Organic Additive Technology
(OAT) coolant (conforming to MS.90032) by an authorized dealer. Check the front of the A/C
condenser for any accumulation of bugs, leaves,
etc. If dirty, clean by gently spraying water from a
garden hose vertically down the face of the
condenser.
Check the engine cooling system hoses for brittle
rubber, cracking, tears, cuts, and tightness of the
connection at the coolant recovery bottle and
radiator. Inspect the entire system for leaks. DO
NOT REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly
could lead to severe internal engine damage. If any
coolant is needed to be added to the system
please contact an authorized dealer.
If the engine coolant (antifreeze) is dirty
or contains visible sediment, have an authorized
dealer clean and flush with Organic Additive
Technology (OAT) coolant (conforming to
MS.90032).
For the proper maintenance intervals
Úpage 272.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from your
radiator. If you see or hear steam coming from
under the hood, do not open the hood until the
radiator has had time to cool. Never open a
cooling system pressure cap when the radi
-
ator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan starts automatically and may
start at any time, whether the engine is
running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the igni -
tion to the OFF mode. The fan is temperature
controlled and can start at any time the igni -
tion is in the ON mode.

Selection Of Coolant
For further information Úpage 326.
NOTE:
Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT)
engine coolant, may result in engine damage
and may decrease corrosion protection. OAT
engine coolant is different and should not be
mixed with Hybrid Organic Additive Technology
(HOAT) engine coolant or any “globally compat -
ible” coolant. If a non-OAT engine coolant is
introduced into the cooling system in an emer -
gency, the cooling system will need to be
drained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032), by an autho -
rized dealer as soon as possible.
Do not use water alone or alcohol-based engine
coolant products. Do not use additional rust
inhibitors or anti-rust products, as they may not
be compatible with the radiator engine coolant
and may plug the radiator.
This vehicle has not been designed for use with
propylene glycol-based engine coolant. Use of
propylene glycol-based engine coolant is not
recommended.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system please contact an authorized dealer.
Adding Coolant
Your vehicle has been built with an improved
engine coolant (OAT coolant conforming to
MS.90032) that allows extended maintenance
intervals. This engine coolant (antifreeze)
can be used up to ten years or 150,000 miles
(240,000 km) before replacement. To prevent
reducing this extended maintenance period, it is
important that you use the same engine coolant
(OAT coolant conforming to MS.90032) throughout
the life of your vehicle.
Please review these recommendations for using
OAT engine coolant that meets the requirements of
the manufacturer Material Standard MS.90032.
When adding engine coolant:
We recommend using Mopar® Antifreeze/
Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT that meets the requirements of the
manufacturer Material Standard MS.90032.
Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of the
manufacturer Material Standard MS.90032
and distilled water. Use higher concentrations
(not to exceed 70%) if temperatures below
−34°F (−37°C) are anticipated. Please contact
an authorized dealer for assistance.
Use only high purity water such as distilled or
deionized water when mixing the water/engine
coolant solution. The use of lower quality water
will reduce the amount of corrosion protection
in the engine cooling system.
NOTE:
It is the owner's responsibility to maintain the
proper level of protection against freezing
according to the temperatures occurring in the
area where the vehicle is operated.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system, please contact an authorized
dealer.
Mixing engine coolant types is not recom -
mended and can result in cooling system
damage. If HOAT and OAT coolant are mixed in
an emergency, have an authorized dealer drain,
flush, and refill with OAT coolant (conforming to
MS.90032) as soon as possible.

288SERVICING AND MAINTENANCE
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that
engine coolant will return to the radiator from the
coolant expansion bottle/recovery tank (if
equipped).
The cap should be inspected and cleaned if there
is any accumulation of foreign material on the
sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is
a regulated substance requiring proper disposal.
Check with your local authorities to determine the
disposal rules for your community. To prevent
ingestion by animals or children, do not store
ethylene glycol-based coolant in open containers
or allow it to remain in puddles on the ground. If
ingested by a child or pet, seek emergency
assistance immediately. Clean up any ground spills
immediately.
Coolant Level
The coolant expansion bottle provides a quick
visual method for determining that the coolant
level is adequate. With the engine off and cold, the
level of the coolant (antifreeze) in the bottle should
be between the “MAX” and “MIN” lines marked on
the bottle.
As long as the engine operating temperature is
satisfactory, the coolant bottle need only be
checked once a month.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant
bottle. Do not overfill.
See an authorized dealer for service.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilo -
meters of operation, you may observe vapor
coming from the front of the engine compartment.
This is normally a result of moisture from rain,
snow, or high humidity accumulating on the
radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze) to
enter the radiator.
If an examination of your engine compartment
shows no evidence of radiator or hose leaks, the
vehicle may be safely driven. The vapor will soon
dissipate.
Do not overfill the coolant expansion bottle.
Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, the contents of the
coolant expansion bottle must also be protected
against freezing.
If frequent engine coolant additions are
required, the cooling system should be pressure
tested for leaks.
Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corro -
sion protection of your engine which contains
aluminum components.
WARNING!
Do not open hot engine cooling system. Never
add engine coolant (antifreeze) when the
engine is overheated. Do not loosen or
remove the cap to cool an overheated engine.
Heat causes pressure to build-up in the
cooling system. To prevent scalding or injury,
do not remove the pressure cap while the
system is hot or under pressure.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.

SERVICING AND MAINTENANCE289
(Continued)
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces -
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically. For the proper maintenance intervals
Úpage 272.
Brake Master Cylinder
The fluid in the master cylinder should be checked
when performing under hood services or
immediately if the “Brake Warning Light” is
illuminated.
Be sure to clean the top of the master cylinder area
before removing the cap. If necessary, add fluid to
bring the fluid level up to the requirements
described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the
brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low
fluid level may be caused by a leak and a checkup
may be needed.
Use only manufacturer recommended brake fluid
Úpage 327.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.
WARNING!
Use only manufacturer recommended brake
fluid Úpage 327. Using the wrong type of
brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in a open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum-based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
