This V-belt transmits power from the engine crankshaft to the air conditioning compressor pulley. It sits in the accessory drive belt system, routing around the compressor clutch and any idler pulleys in the circuit. A worn or glazed belt slips under load, causing the compressor to cycle intermittently or fail to engage, which reduces cabin cooling performance. The belt is manufactured by Contitech and is constructed to the original profile dimensions, matching the pulley groove geometry so that tension remains within the specified range without requiring shimming or adapter pulleys. On installation, ensure the belt is routed according to the drive diagram and tensioned to the manufacturer's specification.
