Idler Roller Pulley for Serpentine Belt, BMW - E65/E66 745Li/760Li

This is the Genuine BMW replacement idler pulley / roller for the main drive belt, often call the serpentine belt or accessory belt. If you are refreshing the belts on your E65/E66 7 series, we highly recommend a fresh idler pulley / roller assembly, and this is the highest quality part you can find for the job. 

This part is specifically for the 2002-2008 BMW 7 Series, including the 745i (short wheel base), the 745Li (long wheel base), and the 760Li. These 7 series were powered by either the N62 V8 engine or the N73 V12 engine, but both of them used this roller / idler pulley on the serpentine accessory belt on the front of the engine.

This is a Genuine BMW E65 idler pulley with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
