Serpentine Drive Belt and Belt Tensioner 1994 Mercedes C280--Not all W202 Models are the same!

I learned that not all Mercedes W202 models use the same belt tensioner device. Be careful when tackling yours. This video will help you!
I decided to replace my serpentine drive belt and belt tensioner because my belt was squeaking and had a few cracks in the ribs. I also knew the belt tensioner is original and after 100,000 miles should be repaired. I was also working on many other parts of the drive belt system so figured might as well. I used either Genuine Mercedes or OEM parts from Meyle, FEBI, or Bosch. I bought all my stuff from either FCP Euro or Pelican Parts.
