It's very important not to neglect your drive belts as a failure will leave you stranded. They're 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.

If you can, inspect and test the pulley and tensioner before ordering your belt. Or plan to order new pulleys and tensioner with your belt. These pulleys use internal bearings which wear out over time. They are also made of plastic and shatter with age, causing potentially expansive/expensive damage to your engine, radiator, etc. The tensioner includes a pulley as one piece but there is an additional lower deflection pulley.

This is a Genuine BMW v-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.
