Mercedes Vito Van 2009 W639 OM646 How To Change The Drive Serpentine Auxiliary Belt How to

As part of our vans service maintenance jobs we're replacing and changing the drive belt, it's a simple job but there's a few things you should know and the right tools are important before doing the job. The belt drives a lot of the important functions e.g. alternator, cooling and power steering pulleys so it's important to replace it e.g. if it's cracking/old to avoid a breakdown etc. We hope our video is helpful if you're looking into doing this job, and thanks for watching!

There's a hole for a torx bit on the tensioner right next to the 12 point nut, you can use either.
