Land Rover Part Number: LR039517 - Drive Belt Tensioner
LR039517 is a drive belt tensioner fitted to 3.0 L V6 and 5.0 L V8 petrol engines. The unit applies and regulates tension on the accessory drive (serpentine) belt, keeping the belt correctly seated and aligned to ensure reliable drive of the alternator, air-conditioning compressor and power-steering pump where fitted. As a spring-loaded pulley assembly, it also dampens belt vibration and compensates for normal belt stretch during operation; replacement is required if the pulley bearing becomes noisy, the tensioner arm binds, or there is visible wear to the belt contact surface.
