Multi-ribbed belts – drive belts for engine accessories

A multi-ribbed belt powers selected engine accessories, such as the alternator or air-conditioning compressor. This category offers belts in different lengths and with different numbers of ribs.

How to choose a multi-ribbed belt

Compare the OE number, length, rib count, engine code and vehicle equipment. Belts of similar lengths are not necessarily interchangeable. Confirm the exact routing.

When should the belt be replaced?

Cracks, fraying, oil contamination and abnormal operation may indicate the need for replacement. Squealing can also be caused by incorrect tension or a worn pulley.

How to prevent a repeat failure

Check the tensioner, idler pulleys and pulley alignment. Install according to manufacturer instructions; do not use belt dressings to conceal slipping instead of making repairs. See belt tensioners.
