Is there a tensioner to adjust a squealing Serpentine belt on 2004 Taurus?

Answer 1

There is also a possibility that an idler bearing has failed but that noise is a bit different from a rubber on metal squealling noise. To be certain of the problem befor you start throwing parts at it is to remove the belt and check each pulley and idler pulley (on the tensioner) for excessive play and/or rough or lumpy feel when you rotate them by hand.

Answer 2

There is a serpentine belt tensioner but there is no adjustment. It's a spring loaded device that's designed to apply tension to the belt. If there is a squealing noise heard, it's a sign that the tensioner has lost tension and the belt is now slipping on pulleys. I recommend replacing both the belt and the tensioner. Tensioner's do not last the life of the vehicle.

Answer 3

NO! The squealing is most likely a dry bearing in one of the devices that the belt is operating. Maybe even the tensioner pulley itself.
