ACCESSORY DRIVE BELT INSPECTION
When inspecting accessory drive belts, small
cracks that run across the ribbed surface of the
belt from rib to rib, are considered normal. This is
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 (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.
BODY LUBRICATION
Locks and all body pivot points, including such
items as seat tracks, door hinge pivot points and
rollers, liftgate, tailgate, decklid, sliding doors and
hood hinges, should be lubricated periodically. Use
a lithium-based grease, such as Mopar® Spray
White Lube to ensure quiet, easy operation and to
protect against rust and wear. Prior to the
application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit;
after lubricating excess oil and grease should be
removed. Particular attention should also be given
to hood latching components to ensure proper
function. When performing other underhood
services, the hood latch, release mechanism and
safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated
twice a year, preferably in the Autumn and Spring.
Apply a small amount of a high quality lubricant,
such as Mopar® Lock Cylinder Lubricant directly
into the lock cylinder.
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.

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 OAT coolant
(conforming to MS.90032).
For the proper maintenance intervals
Úpage 256.
Selection Of Coolant
For further information Ú page 312.
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 antirust 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.
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.

SERVICING AND MAINTENANCE273
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 10 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
Organic Additive Technology (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.
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 so
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,
clean up any ground spills immediately. If ingested,
seek emergency assistance immediately.
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.

Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/
kilometers 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.
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
Ú page 256.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked whenever the vehicle is serviced, or
immediately if the Brake System Warning Light is
on. If necessary, add fluid to bring level within the
designated marks on the side of the reservoir of
the brake master cylinder. Be sure to clean the top
of the master cylinder area before removing cap.
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. If the brake fluid
is abnormally low, check the system for leaks.
For further information Ú page 312.
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 the manufacturer’s recommended
brake fluid Úpage 312. 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.
