Ok so I cut the old belt off as it was frayed really bad and about to fall off anyways. I then loosened the 15mm nut on the tensioner pulley and it ended up coming off all the way. I routed the belt on and put the pulley back on along with the 15mm nut. I tightened it back as good as I possibly could, and when I start the car, it still squeaks really hard and makes an obnoxious noise....What do I need to tighten or do now?
