- Accessory drive: loops over the engine's pulleys to transfer crankshaft rotation to the air-conditioning compressor.
- Direct fit: a replacement for the belt used on the listed applications.
- Signs it may need replacing: cracking, glazing, chunking, squeal, or slipping — inspect and replace the belt if these appear.
The serpentine belt is a routine wear item; if a worn or damaged A/C drive belt is the cause of squeal or a compressor that isn't turning, this belt replaces it. Inspect the tensioner and idler pulleys at the same time, and route the new belt per the vehicle's belt-routing diagram.
