If your alternator belt squeaks, or your power steering belt starts slipping, the noise can be infuriating. With this specially formulated spray from WD-40 Company, squealing belts are no problem at all. Just spray a little WD-40 Specialist Automotive Belt Dressing with the engine running. It penetrates into the cord fibres to restore flexibility and pliability.
How do you use it?

• Shake can well.
• Attach extension tube.
• While engine is running, spray lightly on the inner working surface of the belt - near the smallest or upmost pulley.
• Allow belt to run for several minutes to condition and cure dressing.
• Reapply as needed.

It should not be sprayed on pulleys.
Handy tips:
WD-40 Specialist Automotive Belt Dressing is formulated to extend belt life while providing better grip and traction for all types of belts. It eliminates squeaking & slipping by restoring belts’ pliability & flexibility. It also extends belt life. However, if your belts are cracked or frayed, they should be replaced instead.
