Diagnosis and Testing - Accessory Drive Belt







ACCESSORY DRIVE BELT DRIVE BELT





When diagnosing accessory drive belts, small cracks (1) 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.
