I am confused,
I was told that I need a belt tensioner changed when a water pump is been replaced on a 1993 Mitsubishi 3000 GT VR4, but Auto Zone said it does not need it, who is right here???
Do you know how old the tensioner and idler pulleys are? If no then I would replace them. When I do not know the age of them I replace the tensioner and all idler pulleys. Do you have to change them? No. But for such a small cost now it will give you piece of mind till your next belt change.
Just a reminder. If the tensioner, timing belt or idler pulleys fail you will be re doing your heads due to bent valves.
