The reading of all these posts tell me this fan belt tensioner adjustment is not for the average driver (half mechanic) to mess around with... You can't leave this to just anyone, I'd sleep better knowing an "A" mechanic dealer trained took care of this on my car.. The question is who and where you take the automobile to be fixed right, without some idiot making it worse..
I have adjusted many belts on Jags, MGB's, GTO's whatever... but this car has the German over engineered simple adjustment, made impossible for even a good smart Do it yourself person to get this done ! It's too hard...

All these posts make sense on paper, but way over my head...to try this myself for my W 126 300 SE ...so now where do I take it ?
