Drive Belt: Testing and Inspection
DIAGNOSIS AND TESTING ACCESSORY DRIVE BELT
VISUAL DIAGNOSIS
When diagnosing serpentine accessory drive belts, small cracks (1) that run across the ribbed surface of the belt from rib to rib, are considered normal.
These are not a reason to replace the belt. However, cracks (2) running along a rib (not across) are not normal. Any belt with cracks running along a
rib must be replaced. Also replace the belt if it has excessive wear, frayed cords, severe glazing or chunking.
Any belt with bumb, surface coming apart, or any other uneven indications along the flat surface of the belt must be remove and inspected and
replaced if necessary.
Refer to ACCESSORY DRIVE BELT DIAGNOSIS CHART for further belt diagnosis.
NOISE DIAGNOSIS
Noises generated by the accessory drive belt are most noticeable at idle. Before replacing a belt to resolve a noise condition, inspect all of the
accessory drive pulleys for alignment, glazing, or excessive end play.
