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 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. This is
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. In addition, have the belt
replaced if it has excessive wear, frayed cords,
or severe glazing.

should be carefully inspected for damage and
proper alignment.
