nestorb98, I agree that it is a good time to inspect/replace the fan clutch bearing bracket. If you need a replacement recommend buying a rebuilt one from your local MB dealer. Give them the old one, or you will pay a core charge.

Definitely avoid a Uro tensioner. You can buy a Febi tensioner from Pelican Parts, or a genuine tensioner from your local MB dealer.
