Diagnostic Aids
Excessive wear on a drive belt is usually caused by incorrect installation or the incorrect drive belt for the application
Minor misalignment of the accessory drive belt pulley(s) will not cause excessive wear, but will probably cause the drive belt to make a noise or to fall
off.
Excessive misalignment of the accessory drive belt pulley(s) will cause excessive wear but may also make the drive belt fall off.
Test Description
The number(s) below refer to the step(s) on the diagnostic table.
2. This inspection is to verify that the drive belt is correctly installed on all of the accessory drive belt pulley(s). Wear on the drive belt may be
caused by mispositioning the drive belt by one or more grooves on a pulley(s).
3. The installation of a drive belt that is too wide or too narrow will cause wear on the drive belt. The drive belt ribs should match all of the grooves
on the pulleys.
4. This inspection is to verify the drive belt is not contacting any part of the engine or body while the engine is operating. There should be sufficient
clearance when the accessory drive components load varies. The drive belt should not come in contact with an engine or a body component when
snapping the throttle.
