Belt Squeeks!!!

I just bought a new drive belt then after about 1000miles or so it started to sqeek a little so i got belt dressing for it.It worked for about 2 seconds then got worse and worse over time. Its so damn loud now i cant pop the hood wothout losing an eardrum. Im thinking it might be 1 of the pullies possibley the tensioner. Any ideas?:banghead:

sounds like you have a loose belt, most likely caused by a bad tensioner
