Manufacturer
Product Description
POLY RIB BELT, DAYCO
Features & Benefits
- Powers a big alternator, compressor and fan from one wide band
- Tightly molded rib profile gives every groove a firm, even hold
- Lies flat across broad grooves for smooth, steady operation
- Reinforcing cord core resists elongation across a very wide span
Dayco Serpentine Belt
The Dayco Serpentine Belt spreads its work over twelve ribs, giving every groove on a wide pulley its own line of contact. At about 90.3 inches of effective length, the Dayco 5120903 reaches around the extended pulley route found on some multi-accessory drives. Its cord-reinforced rubber construction helps that long belt flex as the alternator, air compressor and cooling fan draw power. Even wear across so many ribs holds steady traction from cold start to full load.
