Accessory Drive Belt Inspection
When inspecting accessory drive belts, small cracks that run
across the ribbed surface of a belt from rib to rib, are consid -
ered normal. These are not a reason to replace the 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)
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.

NOTE:
If your vehicle is equipped with Stop/Start belt must be
replaced with an OEM grade Mopar belt.
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.
