found out what my squeek is...

I finally got my lazy ass up off the couch and brought my car to my grandfather who was a mechanic for ever until he retired. it tool him about 5 minutes to tell me that it was my belt tensioner. NO NOT THE TIMING BELT TENSIONER!!!! it is the tensioner for the top belt which i believe is the ac belt tensioner. i have looked all over google but cannot find one for sale. if anyone knows where i can pick one up help me.

this has already happened to me in my car and the only thing you can do is by the part from the dealer. the dealer part costs $143.00
