A squealing or chirping belt, a belt that slips, or a wobbling tensioner pulley can mean a worn serpentine belt tensioner. With the engine off and cool, look the belt over for cracks, fraying or glazing and check the pulleys for play first, because the noise may come from one of them rather than the tensioner.
