Recently changed my timing belt but ran into a hiccup. I couldn’t torque down my tensioner pulley. It just reaches a point where i could turn the nut either way and it didn’t get tighter or looser. I presume something is threaded. I have a few questions around this. So far my timing belt hasn’t given me any trouble despite this. How long can/should I expect the belt to stay tight? Has anyone else run into this same problem? And what are my options for fixing this nut/bolt on the tensioner when it comes time to do so?
