Squealing Belt tensioner 99 Cobra

same yr same problem just called ford and they told me my car was still under warranty for another yr even though my paper says it was up last month so hopefully this wont cost anything
does anyone know what the problem is??
 
My car's belt tensioner squealed badly, it's also a problem for the 96's. You'll just have to replace it, I think the part is like 70 dollars, not sure though. It's a p.i.t.a. to change, looks easy but it's time consuming b/c it's hard to get in there to change it.
 
Mine was very easy to take off. took all of 5 mins. I took mine off and used a dremel with a polishing pad to spin the pulley really fast while soaking the bearings(middle of pully on both sides) with wd-40. Mine has sqeuled for about 3 weeks now. Im sure i will eventually have to replace it but it works for now.
