I just put a new Alternator clutch on my2.0tdi CFFB but the new belt is squealing. The tensioner was new a year ago, but doesnt seem to have the tension needed all the time. It can feel loose, or feel ok but starts squealing .

When you move the tensioner bolt, it feels like it is catching and needs pushing back into position. Is something broken? Is there an easy fix or do I just put a new tensioner in?

(I know how difficult it is to do)

Did the vibrations from the old locked alternator pulley break the tensioner?

the videos show turning the bolt clockwise to loosen the fanbelt, but when I do this it tightens it.

I mustve done something wrong.

(if theres an edit button here i cant find it)

The tensioner came out without removing the wheel arch, but I dropped the new one so moved the arch to get at things better. possibly could install from the top otherwise.

The old tensioner is broke, as you can see in the pic.

Not a fun job but easier than last time
