Drive Belt: Testing and Inspection
ACCESSORY DRIVE BELT
When diagnosing serpentine 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 replace
belt if it has excessive wear, frayed cords or severe glazing.
Refer to SERPENTINE DRIVE BELT DIAGNOSIS CHART for further belt diagnosis.
