Dayco 892015 Alternator Decoupler Pulley
- REDUCE VIBRATIONS: To handle variable alternator loads and engine torsional fluctuations, overrunning alternator decoupler pulleys (OAP / OAD) are installed on many late model vehicles. Dayco Alternator Decoupler Pulleys isolate and dampen the drive from the alternator upon deceleration thanks to its one-way clutching capability. The pulley also reduces belt noise and slippage during rapid acceleration or deceleration while improving drive belt tension and prolonging alternator and belt life
- EXTEND SERVICE LIFE: The most common signs of an OAD failure are unusual drive belt noise and vibrations. You may also notice that the alternator does not charge the battery and the pulley spins in both directions. The pulley can also seize. When it comes to its replacement, choose this Dayco product designed to ensure a precise fit and excellent performance
- RELY ON QUALITY AUTO PARTS: Dayco’s essential engine parts and drive system solutions offer engine economy, efficiency, and exceptional performance while minimizing noise, vibration, and harshness. They strive to be first-to-market with built-to-last products such as high-quality engine timing belts, serpentine belts, drive belts, belt tensioners, and more
