Belt-Ease is a clear, clean belt dressing that adds traction, stops belt slippage and helps to silence noisy and irritating squeaks and squeals. Belt-Ease will preserve the life of any automotive fan; as well as alternator, power steering and air conditioner drive belts. The aerosol features a "spray-any-way" valve that even works upside down with an accurate pinpoint spray. Belt-Ease can be used on any application where a drive belt needs to be silenced or maintained. However, Belt-Ease should not be used on serpentine belt applications.
