aux belt tensioner seized?

[mark123]

Hi Just doing my cambelt I couldn't detension the aux belt.

See picture below do I need to slacken A in order to release the tension using the 3/8" square hole?

It looks to me like C should rotate within B without slackening A. This is certainly not the case for my tensioner.

I should add I don't mean is the idler pulley attached to the tensioner seized, that is fine - a little play but normal I reckon and spins freely.

You dont need to slacken anything to detension the belt, you're moving the 3/8" hole against the pressure of the spring

As said above the tool fits into the 3/8 square and u just release the spring pressure to slip the belt off mate.
I made this at work to do mine.

hope that helps.

Are you turning it the right way? You push it towards the back of the car IIRC.

I got it off by cutting the belt and then unbolting it. It was seized, no movement until I undid A in the pic, then it moved fine.

I have my own tool, made from a 1/2 to 3/8 adapter, I was pushing the right way.

I've got a new tensioner and on that one C does rotate within B in my pic.
