Need Help: Serpentine Belt Replacement - 1999 W163
Hi all. I will be replacing my S-Belt tomorrow and would like to get some input from you guys here. I think that I have located the tensioner, but how do I loosen/tighten the tension? There is no adjustment bolt that is visible to me. If anyone has any diagrams or pics that might be able to help me, please post or send me an email or PM. Any help in this matter would be greatly appreciated. Thanks in advance!

Mine was just replaced not long ago. I didn't fix it myself but I remember them saying that the tensioner adjusts dynamically (automatically). The bearing on our tension wheel fell apart, on 2 98's within a month of each other no less. The new part looks much more solidly designed.
Hope that helps a bit. Good luck
