Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop.
The best time to check the engine oil level is about 5
minutes after a fully warmed engine is shut off, or before
starting the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintainthe oil level between the MIN and MAX markings on the
dipstick. Adding one quart of oil when the reading is at
the MIN mark will result in a MAX reading on these
engines.
CAUTION!
Overfilling or underfilling will cause aeration or
loss of oil pressure. This could damage your engine.

Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacture only
recommends engine oils that are API certified and meet
138 MAINTAINING YOUR VEHICLE
Page 139 of 200
the requirements of DaimlerChrysler Material Standard
MS-6395. Use Mopar or an equivalent oil meeting the
specification MS-6395.
The manufacturer recommends the use of Mobil 1t
10W30 synthetic engine oil.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacture only recommends
API Certified engine oils that
meet the requirements of
DaimlerChrysler Material Stan-
dard MS-6395. Use Mopar or an
equivalent oil meeting the specifi-
cation MS-6395.
Engine Oil Viscosity Chart
The proper SAE viscosity grade of engine oil should be
selected based on the following recommendation and be
within the operating temperature shown in the engine oil
viscosity chart.
Synthetic Engine Oils
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, useonlythose oils that meet the Ameri-
can Petroleum Institute (API) and SAE viscosity stan-
dard. Follow the service schedule that describes your
driving type.
Materials Added To Engine Oils
The manufacture strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to

the engine oil. Engine oil is an engineered product and
it's performance may be impaired by supplemental ad-
ditives.
Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil, indiscriminately discarded, can
present a problem to the environment. Contact your
dealer, service station, or governmental agency for advice
on how and where used oil can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
All of this manufacturers engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high quality filters should be used to assure
most efficient service. Mopar Engine Oil Filters are high
quality oil filters and are recommended.
Drive Belts Ð Check Condition and Tension
At the mileage shown in the maintenance schedules,
check all drive belts for condition and proper tension.
Improper belt tension can cause belt slippage and failure.
Inspect the drive belts for evidence of cuts, cracks, or
glazing and replace them if there is any sign of damage
which could result in belt failure. If adjustment is re-
quired, adjust the belts according to the specifications
and procedures shown in the Service Manual.
Special tools are required to properly measure tension
and to restore belt tension to factory specifications. Also,
check belt routing to make sure there is no interference
between the belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Check the specifications section for the proper type
of spark plug for use in your vehicle.

Power Steering Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.9
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Recommended Fluids, Lubricants, and
Genuine Parts for correct fluid types.
Front Suspension Ball Joints
There are two front suspension lower ball joints that are
permanently lubricated. Inspect these ball joints when-
ever under-vehicle service is done. Damaged seals
should be replaced to prevent leakage or grease contami-
nation.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors, trunk and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation 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 compo-
nents to insure 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 fall and spring. Apply a small
amount of a high quality lubricant such as MopartLock
Cylinder Lubricant directly into the lock cylinder.

Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild non abrasive cleaner, or use the washer solvent. This
will remove accumulations of salt or road film and help
reduce streaking and smearing.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield. Avoid using the wiper blades to
remove frost or ice from the windshield. Make sure that
they are not frozen to the glass before turning them on to
avoid damaging the blade. Keep the blade rubber out of
contact with petroleum products such as engine oil,
gasoline, etc.
Windshield Wiper Blade Replacement
1. Lift the wiper arm away from the glass.
2. Rotate the blade 45 degrees to gain access to the
release tab.3. Push the release tab shown in the picture and slide the
wiper blade assembly down along the arm. Gently place
the wiper arm on the windshield.
4. Install the new blade assembly onto the wiper arm tip
until it locks in place.Windshield Washer Aiming
To change the aim of the windshield washers, place a
safety pin into the nozzle opening and move the nozzle
slightly. Continue making slight adjustments until you
obtain the desired pattern.

Windshield Washer Reservoir
The washer fluid reservoir is located in the engine
compartment and should be checked for fluid level at
regular intervals. Fill the reservoir with windshield
washer solvent (not radiator antifreeze)
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if exhaust fumes can be detected inside the vehicle; or
when the underside or rear of the vehicle is damaged;
have a competent mechanic inspect the complete exhaust
system and adjacent body areas of broken, damaged,
deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, inspect the
exhaust system each time the vehicle is raised for lubri-
cation or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide which is colorless and odorless. Breathing
it can make you unconscious and can eventually
poison you. Follow the above precautions to keep
your exhaust system as safe as possible.
