COOLING SYSTEM
Coolant Checks
Check 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 radiator
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 coolant recovery bottle tubing for brittle
rubber, cracking, tears, cuts, and tightness of the
connection at the 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 210.
Selection Of Coolant
For further information Ú page 268.
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.
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 position. The fan is tempera -
ture controlled and can start at any time the
ignition is in the ON position.

226SERVICING AND MAINTENANCE
Coolant Level
The coolant bottle provides a quick visual method
for determining that the coolant level is adequate.
With the engine off and cold, the level of the engine
coolant (antifreeze) in the bottle should be
between the ranges indicated on the bottle.
The radiator normally remains completely full, so
there is no need to remove the radiator/coolant
pressure cap unless checking for engine coolant
freeze point or replacing coolant. Advise your
service attendant of this. As long as the engine
operating temperature is satisfactory, the coolant
bottle need only be checked once a month.
When additional engine coolant is needed to
maintain the proper level, only OAT coolant that
meets the requirements of FCA Material Standard
MS.90032 should be added to the coolant bottle.
Do not overfill.
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.
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 Ú page 210.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the Brake System Warning Light
indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up to
the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because it
may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
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.

Replacing Exterior Bulbs
HIGH INTENSITY DISCHARGE (HID) HEAD -
LAMPS — IF EQUIPPED
The headlamps are a type of high voltage
discharge tube. High voltage can remain in the
circuit even with the headlamp switch off and the
ignition turned to the OFF position. Because of this,
you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle
to an authorized dealer for service.
NOTE:On vehicles equipped with HID headlamps, when
the headlamps are turned on, there is a blue hue
to the lights. This diminishes and becomes more
white after approximately 10 seconds, as the
system charges.
BI-HALOGEN LOW BEAM AND HIGH BEAM
HEADLAMP — IF EQUIPPED
See steps below to replace:

1. Open the hood.

NOTE:Removal of the air cleaner filter housing may be
necessary prior to replacing bulbs in the headlamp
assembly on the driver side of the vehicle.
2. Reach behind the headlamp housing to access the headlamp (outboard) bulb cap.

sockets of HID headlamps when the headlamp
switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced
properly. See an authorized dealer for service.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If
the bulb comes in contact with any oily surface,
clean the bulb with rubbing alcohol.
