Accessory Drive Belt for the 3.0L AJ20D6 Ingenium turbo diesel (High-output variant). This multi-ribbed serpentine belt sits in the accessory drive assembly at the front of the engine, transmitting drive from the crankshaft pulley to the engine ancillaries.

Routed around the drive belt tensioner and idler pulleys, it turns accessories such as the alternator and air-conditioning compressor. A worn belt shows cracking, glazing or fraying of the ribs and should be renewed together with the tensioner and idler pulleys.

Inspect the belt at every service and replace it if any deterioration is found.
