Aux belt / fan belt etc.
I'm getting a slight squeal from around my aux belt area which is irritating me now. It's not loud but I notice it and I want it stopped.
My mechanic said rather nonchalently that the tensioner probably needs replacing.
I asked him if it could simply be re-tightened or whatever, but he said no - on this car the tensioner is self-tensioning and if it starts producing a noise you have to replace it.
Is this right?
