Cooling System
Inspection
WARNING!
²When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition key
to the OFF position. The fan is controlled by both
the temperature of the engine cooling system and
the pressure in the air conditioning system and
can start at any time the ignition key is in the ON
position.
²You or others can be badly burned by hot coolant
or steam from your radiator. If you see or hear
steam coming from under the hood, don't open
the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap
when the radiator or cap is hot.
Coolant Checks
Check coolant protection every 12 months (before the
onset of freezing weather, where applicable). If coolant isdirty or rusty in appearance, the system should be
drained, flushed and refilled with fresh coolant.
Check the front of the radiator for any accumulation of
bugs, leaves, etc. Clean the radiator by gently spraying
water from a garden hose at the back of the core.
Check the recovery bottle tank tubing for condition and
tightness of connections at the bottle. Inspect the entire
system for leaks.
Do not remove the cap when the cooling system is hot.(2.7L Engine Shown)

Cooling System Ð Drain, Flush and Refill
At the intervals shown on the Maintenance Schedules,
the system should be drained, flushed and refilled. The
first change should not be required until 5 years or
100,000 miles (160,000 km), whichever comes first. The
coolant should be flushed and changed every two years
or 36,000 miles (57,600 km) thereafter.
If the solution is dirty and contains a considerable
amount of sediment, clean and flush with a reliable
cooling system cleaner. Follow with a thorough rinsing to
remove all deposits and chemicals. Used automotive
antifreeze is a recyclable commodity. Discard or recycle
as facilities exist in your area.
Selection Of Coolant
Use only the manufacturer's recommended coolant, refer
to Recommended Fluids, Lubricants and Genuine Parts
for correct coolant type.
CAUTION!
Failure to use the proper antifreeze could cause
radiator plugging and engine overheating. Do not
mix antifreeze brands or use plain water alone or
alcohol base antifreeze products. Do not use addi-
tional rust inhibitors or antirust products, as they
may not be compatible with the radiator coolant and
may plug the radiator or heater core.
Adding Coolant
When adding coolant, a solution of 50% ethylene glycol
antifreeze coolant in distilled water should be used. Use
higher concentrations (not to exceed 60%) if temperatures
below -32ÉF (-35ÉC) are anticipated.
Please note that it is the owner's responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
208 MAINTAINING YOUR VEHICLE
Coolant Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant reserve tank.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
The warning words ªDO NOT OPEN HOTº on the
cooling system pressure cap are a safety precaution.
Never add coolant when the engine is overheated.
Do not loosen or remove the cap to cool an over-
heated 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.
CAUTION!
Be sure to use only the cooling system pressure cap
specified for your vehicle. Use of any other pressure
cap may result in decreased engine cooling system
performance and/or damage to your vehicle.
Disposal Of Used Engine Coolant
Used ethylene glycol based engine coolant is a regulated
substance requiring proper disposal. Check with your
local authorities to determine the disposal rules for your
community. Do not store ethylene glycol based engine
coolant in open containers or allow it to remain in
puddles on the ground. Prevent ingestion by animals or
children. If ingested by a child, contact a physician
immediately.
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 coolant level should be between
the ªMINº and ªMAXº marks on the side of the coolant
bottle. Some darkening of the coolant bottle will occur

over time. This is normal. If the coolant level is hard to
see, jostling the coolant bottle will make it easier to see.
There is no need to remove the radiator cap unless
checking for coolant freeze point, adding, 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. Heater
performance may also be adversely affected by low
coolant levels.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do
not overfill. Special procedures are required when filling
the engine cooling system of the 2.7L Engine. See your
authorized dealer for details.
Points to Remember
NOTE:
When the vehicle is stopped after a few miles 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 water 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.
²Do not overfill the coolant bottle.
²Check coolant freeze point in the system.
²If frequent coolant additions are required, or if the
level in the bottle does not drop when the engine cools,
the cooling system should be pressure tested for leaks.
²Maintain coolant concentration of 50% ethylene glycol
(minimum) with recommended antifreeze for proper
corrosion protection of your engine that contains alu-
minum components.
²Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
²Keep the front of the radiator clean. If your vehicle has
air conditioning, keep the front of the condenser clean,
also.
²Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
210 MAINTAINING YOUR VEHICLE
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
Insure nylon tubing in these areas has not melted or
collapsed.
NOTE:Often, fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before hose is replaced based
on leakage.
NOTE:Inspection of brake hoses should be done
whenever the brake system is serviced and every engine
oil change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning lamp shows system failure.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, fill brake fluid reservoir to
the top of the fill mark chevron. With disc brakes, fluid
level can be expected to fall as the brake pads wear.
However, low fluid level may be caused by a leak and a
checkup may be needed.
212 MAINTAINING YOUR VEHICLE
Use only manufacturer's recommended brake fluid, refer
to Recommended Fluids, Lubricants and Genuine Parts
for correct fluid type.
WARNING!
Use of a brake fluid that has a lower initial boiling
point than MOPAR DOT 3 Brake Fluid or that is
unidentified as to DOT FMVSS specification may
result in sudden brake failure during hard or pro-
longed braking. You could have an accident.
WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter.Do not allow petroleum base fluid to contaminate the
brake fluid as seal damage will result!
Fuel System Hoses
Electronic Fuel Injection high pressure fuel systems are
designed with hoses and clamps which have unique
material characteristics to provide adequate sealing and
resist attack by deteriorated gasoline.
You are urged to use only manufacturer specified hoses
and clamps, or their equivalent in material and specifi-
cation, in any fuel system servicing. It is mandatory to
replace all clamps that have been loosened or removed
during service. Care should be taken in installing new
clamps to insure they are properly torqued.
Automatic Transmission
Your front wheel drive vehicle has a transmission and
differential assembly contained within a single housing.
This is referred to as a ªTransaxle.º
MAINTAINING YOUR VEHICLE 213

Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturers recommended transmis-
sion fluid, refer to Recommended Fluids, Lubricants and
Genuine Parts for correct fluid type. It is important that
the transmission fluid be maintained at the prescribed
level using the recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turers recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturers recommended fluid will result in
more frequent fluid and filter changes. Refer to
Recommended Fluids, Lubricants and Genuine Parts
for correct fluid type.
Procedure For Checking Fluid Level
The fluid level in the automatic transaxle should be
checked whenever the vehicle is serviced. Operation with
an improper fluid level will greatly reduce the life of the
transaxle and of the fluid.
To properly check the automatic transaxle fluid level, the
following procedure must be used:
²The vehicle must be on level ground.
²The engine should be running at curb idle speed for a
minimum of 60 seconds.
²Fully apply parking brake.
²Place the gear selector momentarily in each gear
position ending with the lever in P (PARK).
²Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
²If the fluid is cold (80ÉF / 27ÉC), the reading should be
in the cross hatched area marked ªCOLDº (between
the lower two holes in the dipstick).
