Since the 1960s, when cars were more straightforward, advances in technology have led to more parts that need power. The serpentine belt transfers power from the crankshaft to the cooling fan, the power steering unit, the water pump, the air-conditioning unit, and many more parts. If the Serpentine Belt breaks, all these parts will cease working, and your engine will overheat and die.

The serpentine belt is subject to wear over time. The belt is called serpentine because of the way it snakes from one unit to another providing power to auxiliary units which modern drivers consider essential. Every unit the belt powers gives a little more stress to the belt fabric. Signs of wear including cracking and fraying indicate a need to replace your belt.

At Wynn Volvo Cars Norristown in Norristown, PA, we can check your serpentine belt for signs of wear during every oil service.
