Dayco Heavy Duty Serpentine Belt

The Dayco Heavy Duty Serpentine Belt is a multi-rib drive belt (also called a serpentine drive belt or poly-V belt) that transfers engine power 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, and this line is intended for demanding service.

Key Features:

• Multi-rib design that drives several accessories from one belt
• Durable synthetic rubber construction built for heat, wear, and long service life
• Reinforced tensile cords that help control stretch and keep belt tension stable
• Precision-molded ribs that grip the pulleys for quiet, reliable operation
• Designed to resist cracking, oil, and abrasion in harsh under-hood conditions

Replacing a worn serpentine belt helps prevent slippage, squealing, and accessory failure. For best results, inspect the tensioner and pulleys during installation. Select the correct belt for your application by choosing the individual part number from the product group.
