Dayco Serpentine Belt Poly V-Belt

The Dayco serpentine belt (also called a poly-V belt, multi-rib belt, or accessory drive belt) transfers power from the engine crankshaft to accessories such as the alternator, water pump, power steering pump, and air conditioning compressor. Dayco is a long-established maker of belts and engine drive components. Its serpentine belts are built to run quietly and reliably in demanding engine environments.

Key Features:

• Multi-rib (poly-V) design that grips pulleys for efficient power transfer to every driven accessory
• Durable synthetic rubber construction that resists heat, oil, and wear
• Reinforced tensile cords provide strength and help limit stretch over time
• Designed for smooth, quiet operation with low vibration
• Precision-ribbed profile helps keep alignment on the pulleys
• Manufactured to meet or exceed original equipment performance expectations

Replacing a worn serpentine belt on schedule helps prevent squealing, slipping, and accessory failure. It also helps avoid unexpected breakdowns. Check the exact belt length and rib count in the individual item listing to select the correct belt for your application.
