This belt tensioner and pulley assembly is designed to maintain the correct tension on your vehicle's accessory drive belt. Proper belt tension is crucial for the efficient operation of components like the alternator, power steering pump, and air conditioning compressor. Over time, tensioners can wear out, leading to a loose belt that slips, causing noise and reduced performance of driven accessories. A worn pulley bearing can also cause noise and premature belt wear. This part is a direct fit replacement for the original equipment on specific PEUGEOT/CITROEN models, ensuring compatibility and ease of installation. Replacing a worn tensioner and pulley with this unit will restore proper belt function and prevent potential damage to other components.
