BMW N54 Drive Belt Kit - Tensioner - Pulleys - Belt

Your BMW's serpentine drive belt system is important for numerous reasons. The primary purpose of drive belts is to "drive" the accessories that make your vehicle run and function properly. The N54 engine only uses one serpentine belt but that one serpentine belt is responsible for driving the alternator, power steering pump, and A/C compressor.

The drive belt is not the only component of the drive belt system that's critical. The tensioner dampers and pulleys all play a role in keeping the drive belts properly tensioned and guided under all engine loads. Belts can stretch with higher engine loads and the tensioners and pulleys must maintain proper tension on the belts or they can fall off resulting in serious problems. These components also have a service life and should be replaced as needed.

This comprehensive kit is designed to service the entire drive belt system in one service. It includes OE Contitech drive belts and all OE INA pulleys/tensioners to ensure a long service life.

Please note: The belt tensioner comes with its own encapsulated bolt and is torqued to 40nm of torque. The 80mm and 90mm idler pulley both include M10x40 encapsulated mounting bolts which are torque to 38Nm of torque.
