Accessory Drive Belt Inspection
When inspecting accessory drive belts, small cracks that run
across ribbed surface of belt from rib to rib, are considered
normal. These are not a reason to replace belt. However,
cracks running along a rib (not across) are not normal. Any belt with cracks running along a rib must be replaced. Also
have the belt replaced if it has excessive wear, frayed cords
or severe glazing.
Accessory Belt (Serpentine Belt)
Conditions that would require replacement:

• Rib chunking (one or more ribs has separated from belt body)

• Rib or belt wear
• Longitudinal belt cracking (cracks between two ribs)
• Belt slips
• “Groove jumping" (belt does not maintain correct position on pulley)
WARNING!
• Do not attempt to inspect an accessory drive belt with vehicle running.
• When working near the radiator cooling fan, discon -
nect the fan motor lead. The fan is temperature
controlled and can start at any time regardless of igni -
tion mode. You could be injured by the moving fan
blades.
• You can be badly injured working on or around a motor vehicle. Only do service work for which you have the
knowledge and the proper equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.

• Belt broken (note: identify and correct problem before newbelt is installed)
• Noise (objectionable squeal, squeak, or rumble is heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty component such
as a belt pulley. Belt pulleys should be carefully inspected for
damage and proper alignment.
Belt replacement on some models requires the use of special
tools, we recommend having your vehicle serviced at an
authorized dealer.
Body Lubrication
Locks and all body pivot points, including such items as seat
tracks, door hinge pivot points and rollers, liftgate, tailgate,
decklid, sliding doors and hood hinges, should be lubricated
periodically with a lithium based grease, such as Mopar
Spray White Lube 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 ensure 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 Mopar Lock Cylinder Lubri
-
cant directly into the lock cylinder.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the wind -
shield periodically with a sponge or soft cloth and a mild
nonabrasive cleaner. This will remove accumulations of salt
or road film.
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. Keep the blade rubber out of contact with petro -
leum products such as engine oil, gasoline, etc.

518 SERVICING AND MAINTENANCE
NOTE:
Life expectancy of wiper blades varies depending on
geographical area and frequency of use. Poor performance of
blades may be present with chattering, marks, water lines or
wet spots. If any of these conditions are present, clean the
wiper blades or replace as necessary.
The wiper blades and wiper arms should be inspected peri-
odically, not just when wiper performance problems are
experienced. This inspection should include the following
points:
• Wear or uneven edges
• Foreign material
• Hardening or cracking
• Deformation or fatigue
If a wiper blade or wiper arm is damaged, replace the
affected wiper arm or blade with a new unit. Do not attempt
to repair a wiper arm or blade that is damaged. Wiper Blade Removal/Installation
1. Lift the wiper arm to raise the wiper blade off of the glass,
until the wiper arm is in the full up position.
Windshield Wiper ArmCAUTION!
Do not allow the wiper arm to spring back against the
glass without the wiper blade in place or the glass may
be damaged.
