Your serpentine belt is most likely loose or badly worn and in need or replacement. It is possible that the belt tensioner is going bad. Or, it is possible that a bearing in either the belt tensioner or the belt idler pulley is going bad. If a bearing in the tensioner or idler pulley seizes up, you will likely lose the belt and wind up stranded. A visit to your mechanic is needed at this time. ---
