Product Description
AUTOMATIC BELT TENSIONER, HD, DAYCO
Features & Benefits
- Automatic spring mechanism maintains steady belt pressure
- Clockwise rotation design matches designated pulley systems
- Heavy-gauge steel arm provides a strong pivot structure
- Smooth pulley surface guides serpentine belt alignment
- Integrated damping spring reduces vibration during engine operation
Dayco Automatic Drive Belt Tensioner
The Dayco Automatic Drive Belt Tensioner maintains consistent belt pressure across engine-driven accessories without manual adjustment. Built as an automatic unit, it reacts to belt stretch and wear by adjusting spring force to keep proper tension on the serpentine belt. Its clockwise direction matches engine configurations designed for that rotation path. Stable belt tension helps prevent slipping, squealing, or uneven accessory drive operation. Designed specifically for serpentine belt systems, it integrates into multi-pulley layouts common in modern engines. The Dayco 89481 supports accessory drive performance in compatible applications.
