NSPECTION
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 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)
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)

Belt broken (note: identify and correct problem
before new belt 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.

UBRICATION
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 ensure 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 Autumn and Spring.
Apply a small amount of a high quality lubricant,
such as Mopar® Lock Cylinder Lubricant directly
into the lock cylinder.
WARNING!

Do not attempt to inspect an accessory drive
belt with vehicle running.

When working near the radiator cooling fan,
disconnect the fan motor lead. The fan is
temperature controlled and can start at any
time regardless of ignition 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 equip -
ment. If you have any doubt about your ability
to perform a service job, take your vehicle to a
competent mechanic.
