Genuine BMW Drive Belt Tensioner, Belt and Idler Pully Kit N55 F Series

NOTE: This product does not work on active hybrid vehicles

If the accessory belt is loose in your vehicle, and without the proper tension your generator, and AC might not work properly. Alternatively, if your belt snaps constantly, the tensioner could be too tight.

With either problem, the only solution is a new tensioner. This Genuine BMW Tensioner Kit is a factory direct replacement for an original, worn out unit. It applies the proper amount of tension to the belt to keep it tight against all of the accessory pulleys.

Kit includes:

- Tensioner With Replacement Bolt

- Replacement Pully

- Accessory Belt

This kit is compatible with the N55 powered F30, F32, F33, F34, and F36
