Belt Conditioner

Engine Accessories

Restores flexibility and surface grip to engine accessory belts to reduce squealing and improve power transmission efficiency.

Belt conditioner is applied to serpentine belts and V-belts to restore their elasticity and improve friction with pulleys. As belts age, they can become hard and glazed, reducing grip and causing squealing or slippage. Regular conditioning helps extend belt life and reduce noise, though it is not a substitute for belt replacement when wear is severe.
