Product Description
AUTOMATIC BELT TENSIONER, HD, DAYCO
Features & Benefits
- Maintains optimal belt tension for efficient power delivery to your engine's accessories

Dayco Automatic Belt Tensioner
The Dayco Automatic Belt Tensioner eliminates the guesswork from maintaining optimal engine performance. This intelligent component automatically regulates belt tension, ensuring a smooth flow of power to your engine's vital accessories. Dayco's secret lies in its patented "flat spring" mechanism that minimizes tension fluctuations, a major cause of premature wear on accessory bearings during new belt installations. An embedded PTFE string within the spring further enhances the system by providing superior abrasion resistance for the belt and dampening noise for a quieter operation. Manufactured with unwavering commitment to longevity, the Dayco 89440 boasts a weatherproof construction that repels harsh elements and extreme temperatures.
