Well my alternator belt broke last month. I put a new one on and sure enough It broke or came off this morning! I am so pissed! The belt started squeeling two days after I put it on and figured it just needed a little tightening. I thought it was a little loose when I first installed it but it wasn't making any noise at the time so I let it be. Then when it started making noise I didn't have the time to tighten it. I was planning on doing it this weekend. Man I've been having some really bad luck lately! Everyone make sure you do things right the first time. Your only screwing yourself if you don't! It's going to be freezing out there today when I'm trying to do this!
