Product Description

Ensure your BMW's engine runs smoothly with the Arrowhead Tensioner Unit V Belt, designed specifically for the ENGINE VEE BELT TENSIONER system. This essential component maintains the correct tension on the V-belt, which is crucial for driving various engine accessories like the alternator, power steering pump, and air conditioning compressor. Proper belt tension prevents slippage, noise, and premature wear, helping your engine operate efficiently.

This tensioner unit is compatible with selected BMW models, including F20, F30, E84, F25, E89, and engine variants such as 125i, 320i, 20i, and 28i with the N20 engine. Always confirm your vehicle's model, year, engine size, and engine code to ensure correct fitment before ordering.

Common signs that your V-belt tensioner may need replacement include squeaking or chirping noises from the belt area, visible belt slack, erratic engine accessory performance, or warning lights related to charging or power steering. If you notice any of these symptoms, prompt inspection is recommended.

Replacing the tensioner unit restores proper belt tension, reducing the risk of belt failure and preventing potential damage to other engine components. It is advisable to replace the V-belt at the same time for optimal reliability.
