A/C Belt, 4PK0803, BMW - E70 X5 3.0si

This the drive belt for the A/C system on 2007-2010 E70 X5 3.0si models with the N52 6-cylinder engine.

A belt is easy to inspect during normal maintenance such as an oil change or refilling your washer tank. If there are cracks running across the ribs, sections missing, the edges are frayed, or the threads are visible on the belt surface, the belt should be replaced immediately. Also pay attention to a belt that is running off the edge of a pulley as that is a sure sign of an impending catastrophic failure.

Also test the belt tensioner at the same time as the pulleys. A failing tensioner can let the belt slip off the pulleys. Due to the severity of failure, we recommend replacing the tensioner every 50-60,000 miles. But you might as well do it with every belt change.

This is a Genuine BMW X5 A/C belt 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.
