Checking why my AC wasn't working.... took a look and the belt skipped off. I put it back on and tightened it down and tried to start it up. When I looked it was off again. One more time for good luck and it was off again. I think the radiatior belt protector pulley thing is making it do that. Tried messing with that and it wouldn't budge. Figured I would stop and have a beer before I broke something. Any suggestions?????????
