Dayco Poly Cog Serpentine Belt

The Dayco Poly Cog Serpentine Belt is an OE-style multi-rib drive belt (also called a poly-V belt, accessory drive belt or serpentine drive belt). It transfers engine power to accessories such as the alternator, power steering pump, water pump and air conditioning compressor. Dayco is a long-established name in belts, hoses and engine drive components.

Key Features:

• Cogged (notched) backing that adds flexibility and helps the belt wrap tightly around small-diameter pulleys
• Multi-rib design that gives smooth, quiet power transmission
• Synthetic rubber construction that resists heat, oil and wear
• Reinforced tensile cords that resist stretch and help hold tension
• Precision-molded ribs that keep alignment accurate and reduce noise and vibration

Replacing a worn serpentine belt helps prevent squealing, slipping, cracking and a sudden loss of accessory drive. Check the tensioner and idler pulleys when you install a new belt, because worn pulleys shorten belt life. Choose the child item that matches the belt you need.
