Collection: Serpentine belt pulleys

Multi-ribbed belt pulleys – reliable auxiliary drive

Pulleys guide the multi-ribbed belt that powers engine accessories, including the alternator and air-conditioning compressor on some vehicles. Noise, vibration or uneven belt travel calls for diagnosis of the entire drive system.

Idler and tensioner pulleys

Identify the pulley's function and compare its diameter, width, running surface and mounting method. Check whether the listing includes a pulley alone or a complete tensioner. Accessory equipment such as air conditioning may affect the correct variant. Inspect the belt and other drive parts during replacement.
