Maintain a perfectly tensioned belt and optimal accessory performance with the first-rate Dayco Automatic Belt Tensioner. Its innovative design incorporates a patented "flat spring" mechanism that minimizes tension variation, reducing the risk of premature accessory bearing failure due to excessive tension during new belt installation. There’s also a PTFE string wound within the spring, providing abrasion resistance and dampening noise for a smoother and quieter operation. Acting as the silent guardian of your engine's accessory drive system, the Dayco 89203 automatically adjusts belt tension to compensate for wear and varying engine loads.
