Joshua

Originally, I was scheduled to work with another mechanic, who is no longer available with YourMechanic. I was told that Josh would be taking over the work on my Mercedes, but that I would have to wait a week for his next available appointment. My first experience with Josh was a very positive one. He is very professional, upbeat and friendly. He arrived early, explained the issue at hand very well and was very clear and concise about next steps. He found that my original mechanic only found part of the problem with my car, not the whole issue. So he comped the labor and parts from his visit and scheduled a follow up appointment with me to install the final part and complete the job. Thank you very much, Josh!

All about Drive Belt Tensioner Replacement

A Drive Belt Tensioner is a pulley mounted to either a spring mechanism or to an adjustable pivot point that is used to keep constant tension on your serpentine belt. That is the big long belt in the front of your engine. The tensioner rides on the outside surface of the belt to put pressure, or tension, on the belt and against the pulleys that drive things like the alternator, power steering, air conditioner, etc.
