ACCESSORY DRIVE BELT
INSPECTION
WARNING!
•
Do not attempt to inspect an accessory drive belt
with the vehicle running.
•
When working near the radiator cooling fan, dis-
connect 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 the ribbed surface of the belt, from rib to rib,
are considered normal. These are not a reason to replace
a 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 posi-
tion on pulley)
•
Belt broken
•
Noise (objectionable squeal, squeak, or rumble is
heard or felt while drive belt is in operation)
NOTE:
Identify and correct problem before new belt is
installed.
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 ser-
viced at an authorized dealer.
