This multi-ribbed belt drives the air-conditioning compressor from the engine crankshaft pulley. It sits in the accessory drive system, routing power to the compressor clutch assembly. A worn or glazed belt slips under load, reducing compressor speed and lowering cabin cooling efficiency. The belt is manufactured by Continental, a supplier of original-equipment drive belts. Its rib profile matches the pulley grooves of the original assembly, maintaining proper tension and preventing belt walk. On installation, verify belt tension against the manufacturer's specification and replace the tensioner if it shows signs of wear.
