Dayco Automatic Belt Tensioner Assembly (MPN: 89264)

Engineered for optimal serpentine belt performance and longevity.

The Dayco Automatic Belt Tensioner Assembly is designed to maintain consistent tension on serpentine belt drives, which power various engine accessories. Utilizing an original flat spring design, this tensioner minimizes variations in tension during operation, thereby reducing the risk of premature accessory bearing failure. The innovative construction helps mitigate issues such as belt noise, slippage, and poor accessory performance that can arise from low tension as the belt wears over time.

Constructed with a heavy-duty cast aluminum spring case and arm, the Dayco tensioner offers enhanced strength and durability, resisting cracking and fatigue under demanding conditions. The inclusion of a PTFE strip within the spring provides abrasion resistance, while lubricated nylon bushings ensure quieter operation. Additional features such as a rubber
