230SERVICING AND MAINTENANCE
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 engine coolant in the bottle
should be between the “MIN” and “MAX” marks.
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 an authorized dealer of this. As
long as the engine operating temperature is
satisfactory, the coolant only needs to 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/
kilometers of operation, you may observe vapor
coming from the front of the engine compart -
ment. This is normally a result of moisture from
rain, snow, or high humidity accumulating on the radiator and being vaporized when the ther
-
mostat opens, allowing hot engine coolant 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 pres -
sure tested for leaks.
Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper
corrosion 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
necessary, install ONLY the correct type ther -
mostat. Other designs may result in unsatis -
factory 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 217.
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.
