Belt dressing instantly eliminates squeaks and squeals common in engine belts. A noisy belt isn’t always a sign that a belt needs replacing. In many cases the squeaking comes as a result of lost traction and belt slippage. Auto belt dressing adds traction between the belt and the pulley and prevents slippage of the belt caused by conditions including heat, cold, moisture and glazing.

Valvoline's belt dressing spray is designed for application to all flat-ribbed and V-belts. Auto belt dressing spray is applied to both the pulley and the belt while the engine is off and then distributed evenly as the engine idles upon startup. The no-stick formula preserves pulley contact areas because it does not pick up dirt or dust particles. Belt dressing also provides a protective coating to reduce future deterioration.
