If your water pump or alternator belt tensioner has failed because of the pulley or bearing, this replacement pulley is all you need to get your BMW back on the road! BMW and other brands usually sell the tensioner with the metal arm included, which increases the cost, even though the arm often doesn't need replacement. This OEM replacement is a much more affordable option, saving you $150 or more compared to the Genuine BMW tensioner.

This is an OEM INA Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).
