Steering Shaft Seal
The steering shaft seal, at the point where the shaft passes
through the bulkhead, is lubricated when it is installed. If
the seal becomes noisy when the steering shaft is turned,
it should be lubricated with a multi-purpose grease.
Mopar multi-purpose lubricant is recommended.
Steering Linkage
The tie rod end ball joints are permanently lubricated and
do not require periodic maintenance.
Drive Shaft Universal Joints
Your vehicle has constant velocity universal joints. Peri-
odic lubrication of these joints is not required. However,
the joint boots should be inspected for external leakage or
damage when other maintenance is performed. If leakage
or damage is evident, the universal joint boot and grease
should be replaced immediately. Continued operation could result in failure of the univer-
sal joint due to water and dirt contamination of the
grease. This would require complete replacement of the
joint assembly.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors, liftgate, sliding doors and hood hinges,
should be lubricated periodically to assure 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 insure proper function. When performing
other underhood services, the hood latch, release mecha-
nism and safety catch should be cleaned and lubricated. MAINTAINING YOUR VEHICLE 391

WARNING!• The warning words “ DO NOT OPEN HOT ” on
the cooling system pressure cap are a safety pre-
caution. Never add coolant 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.
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. To prevent ingestion by animals or children do not store ethylene glycol based engine coolant in open
containers or allow it to remain in puddles on the
ground. If ingested by a child, contact a physician
immediately. Clean up any ground spills immediately.
Coolant Level
The coolant recovery bottle provides a quick visual
method for determining that the coolant level is ad-
equate. With the engine cold, the level of the coolant in
the coolant recovery bottle should be between the
“ MAX ” and “ MIN ” marks. The radiator normally re-
mains completely full, so there is no need to remove the
radiator cap except for checking coolant freeze point or
replacement with new antifreeze coolant. Your service
attendant should be advised of this. So long as the engine
operating temperature is satisfactory, the coolant recov-
ery bottle need only be checked once a month. MAINTAINING YOUR VEHICLE 397

• Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance.
• Increasing engine speed at idle does not reduce cool-
ant temperature! Put transmission in NEUTRAL and
let engine idle at normal engine idle speed.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component which may cause heat
damage or mechanical wear. Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of wear or damage that could cause failure.
Brakes
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the Mainte-
nance Schedules. MAINTAINING YOUR VEHICLE 399

WARNING!Riding the brakes can lead to brake failure and
possibly an accident. 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 wouldn ’ t have your full
braking capacity in an emergency.
Brake And Power Steering Hoses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, tears, cuts, abrasion, and excessive swelling
indicate deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold. Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
NOTE: Often, fluid such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to facilitate the assembly of hoses to couplings.
Therefore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping of
hot fluid when systems are under pressure (during
vehicle operation), should be noted before hose is re-
placed based on leakage.
NOTE: Inspection of brake hoses should be performed
whenever the brake system is serviced and every engine
oil change. Inspect hydraulic brake hoses for surface
cracking, scuffing, or worn spots. If there is any evidence
of cracking, scuffing, or worn spots, the hose should be400 MAINTAINING YOUR VEHICLE

replaced immediately! Eventual deterioration of the hose
can take place resulting in a possibility of a burst failure.
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 — ABS Brakes Brake Fluid Level
Check
The fluid level in the master cylinder should be checked
when performing underhood services, or immediately if
the brake system warning light indicates system failure.
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 require-
ments described on the brake fluid reservoir. 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.
Use only manufacturers recommended brake fluid, refer
to Recommended Fluids, Lubricants and Genuine Parts
for correct fluid type.
WARNING!Use of brake fluid that may have a lower initial
boiling point or unidentified as to specification, may
result in sudden brake failure during hard pro-
longed braking. You could have an accident. MAINTAINING YOUR VEHICLE 401

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 or
moisture.
CAUTION!Do not allow petroleum base fluid to contaminate
the brake fluid, all brake seal components could be
damaged causing partial or complete brake failure. Fuel System Hoses
Electronic Fuel Injection high pressure fuel systems are
designed with hoses which have unique material charac-
teristics to provide adequate sealing and resist attack by
deteriorated gasoline.
Use only the manufacturers specified hoses 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
The automatic transmission and differential assembly are
contained within a single housing.
All automatic transmissions are equipped with a conven-
tional filler tube and dipstick. If fluid is added, it should
be added through the dipstick hole in the case.402 MAINTAINING YOUR VEHICLE

Procedure For Checking Fluid Level
The fluid level in the automatic transmission should be
checked whenever the vehicle is serviced. Operation with
an improper fluid level will greatly reduce the life of the
transmission and of the fluid.
To properly check the automatic transmission fluid level,
the following procedure must be used:
1. The vehicle must be on level ground.
2. The engine should be running at curb idle speed for a
minimum of 60 seconds.
3. Fully apply parking brake.
4. Place the gear selector momentarily in each gear
position ending with the lever in P (PARK). Wipe the area
around the dipstick clean to eliminate the possibility of
dirt entering the transmission. 5. Remove the dipstick and determine if the fluid is hot
or warm. Hot fluid is approximately 180 ° F (82 ° C), which
is the normal operating temperature after the vehicle has
been driven at least 15 miles (24 km). The fluid cannot be
comfortably held between the finger tips. Cold is when
the fluid is below 80 ° F (27 ° C).
6. Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
a. If the fluid is hot, the reading should be in the
crosshatched area marked “ HOT ” (between the upper
two holes in the dipstick).
b. If the fluid is cold, the fluid level should be between
the lower two holes in the area marked “ COLD ” .
If the fluid level indicates low, add sufficient fluid to
bring to the proper level.404 MAINTAINING YOUR VEHICLE

The Heated Mirrors, Lower Instrument Panel Power
Outlet and Removable Floor Console, when in the front
position are fused with self resetting fuses that are only
serviceable by an authorized dealer. The power seats are
fused by a 30 Amp circuit breaker located under the
driver ’ s seat. The Power Windows are fused by a 25 Amp
circuit breaker located under the instrument panel near
the steering column. If you experience temporary or
permanent loss of these systems see your authorized
dealer for service.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
• Remove the 20 Amp mini fuse in the Integrated Power
Module labeled Ignition-Off Draw (IOD).
• Or, disconnect the negative cable from the battery. • Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
