The belt's only job is to transfer power to all accessories by wedging the belt ribs into the pulley, creating friction. The tension needed to create the wedging force is provided by the tensioner.


Belt material changed for Neoprene to EPDM in the late 1990's which changed the belt inspection process from looking for cracks to checking rib wear.


EPDM belts wear out gradually, much like a tire, and typically don't show the physical signs of wear (cracking, chunking, pilling, etc.) that Neoprene belts did.


FunctionTransfers power from one component to another. For example the serpentine belt transfers power from the crankshaft to the alternator.


Signs of WearCracking, splitting and/or squealing belt, dimming headlights while driving, loss of battery charge.
