Dayco Poly Rib Serpentine Belt

The Dayco Poly Rib Serpentine Belt (also called a multi-rib belt, drive belt or accessory drive belt) is built to drive the alternator, power steering pump, water pump, air conditioning compressor and other engine accessories from a single belt. Dayco is a long-established maker of belts and engine drive components, and this line is designed to deliver smooth, reliable power transmission.

Key Features:

• Poly-rib design with multiple longitudinal ribs for strong grip and efficient power transfer across the pulleys
• Flexible construction that helps the belt wrap tightly around small-diameter pulleys
• Durable rubber compounds and reinforced tensile cords for resistance to heat, wear, oil and cracking
• Quiet operation with consistent tension, which helps reduce slippage and noise
• Manufactured to meet or exceed original equipment performance expectations

Replacing a worn serpentine belt helps protect accessory components and keeps the charging, cooling and steering systems working properly. Check the belt, tensioner and pulleys at each service interval. Replace the belt if you see cracking, fraying, glazing or missing ribs. Choose the correct belt length and rib count for your application from the available options.
