Product Description

The Arrowhead Tensioner Unit V Belt is a crucial component in the engine vee belt tensioner system for selected BMW models. This part maintains the correct tension on your engine's V-belt, ensuring smooth operation of critical accessories such as the alternator, water pump, and air conditioning compressor. Its robust aluminium housing and dual pulley design provide reliable belt alignment and tension throughout varied engine speeds and loads.

This tensioner unit is designed specifically for various BMW models, including popular options like the F20, F21, F22, E90, F30, F10, and the X1 to X6 series with N47 and N57 diesel engines. Always confirm your vehicle's model, year, engine size, and engine code before ordering to ensure the correct fitment for your BMW.

Common symptoms of a failing vee belt tensioner include squealing or chirping noises from the belt area, visible belt misalignment, excessive belt wear, engine accessory malfunction, or a loss of power steering and air conditioning. You may also notice vibrations or rattling sounds from the engine bay, especially at start-up or under load.

If you experience any of these issues, it is recommended to inspect and replace the tensioner unit promptly. Delaying replacement can lead to belt slippage or breakage, resulting in further engine accessory damage and potential breakdowns.
