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! #mercedesw639
