A very quick shot of a water displacement spray will do the trick. CRC or WD40. Not much. If you use belt dressing...it will sing to you as it's sticky. Before doing anything... take a wooden do well and, with the engine running, place the end of the dowel against your idler pulley. If so equipped...making sure not to get it unto moving parts. Put your ear to the other end of the dowel. If you Hear a high pitched whine...change the idler bearing or assembly. If you hear any low pitch, listen to the water pump... then the power steering pump...then the AC pump...if none are whining...spray the belts very lightly. A belt will dry-rot...and will sing. A small amount of water displacement fluid will quiet down your problem...but change your belts when you can. W.A.L. Chattanooga///
