Dayco 89200A Automatic Belt Tensioner Assembly

The Dayco 89200A is an automatic belt tensioner assembly designed to maintain constant tension on serpentine belt drive systems in automotive applications. This tensioner features Dayco's patented No Slack flat spring design that provides consistent operating range with minimal tension variation, helping to extend accessory bearing life and prevent premature belt wear.

Key Features:

• Patented flat spring design for less operating range variation compared to coil spring tensioners
• Reduces risk of premature accessory bearing failure from excessive tension
• Minimizes belt noise and slippage associated with low tension conditions
• Lifetime lubricated bearing for long-lasting, maintenance-free performance
• Durable construction engineered to meet or exceed OEM specifications
• Direct-fit replacement for factory tensioner assembly

Dayco automatic belt tensioners are engineered to endure demanding underhood conditions while promoting quieter operation and longer service life. The flat spring technology maintains more consistent belt tension throughout the operating range compared to conventional coil spring designs, helping ensure optimal performance of all belt-driven accessories including alternators, power steering pumps, air conditioning compressors, and water pumps.
