CCESSORY RIVE ELT NSPECTION
WARNING!
 Do not attempt to inspect an accessory drive belt
with the 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 position.
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.
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 posi-
tion on pulley)
 Belt broken (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)
