1997Stang

I installed my underdrive pulleys on my 97gt a while ago and put it away for the winter, but i went to take it out today and when i started it and started driving their is a really loud squeaking noise coming from what it seems to be the belt tensioner or something in that area. I cannot figure out what it is. I sprayed WD40 on the tensioner and it stopped for a while and then came back. Anyone have any idea wha this is? Please help.

Thanks,
Mike

buy a new belt... and while your changing your belt....when the belt is off... spin all your pullies (expect your crank bc u wont be able to by hand) and see if any squeak or feel rough or loose
