Accessory Drive Belt Inspection

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 equipment. If you have any
doubt about your ability to perform a ser-
vice job, take your vehicle to a competent
mechanic.
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.
216
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 prob-
lem 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.

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 periodi-
cally with a lithium based grease, such as Mopar
Spray White Lube to assure quiet, easy opera-
tion and to protect against rust and wear. Prior to
the application of any lubricant, the parts con-
cerned 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 Lubricant directly
into the lock cylinder.
