That could easily be just the pulley. Most likely your tensioner is fine. Replace it and be done before the thing does come flying off and you need a new belt and overheat your engine. No use in speculating. Plus if the tensioner is also shot you should be able to tell that there isn't good resistance when you try to relieve the pressure. In any case your pulley is def gone so order that up first. You might as well get the idler pulley too because that is probably also shot or will be soon.
