Dayco Elastic Self-Tensioning Serpentine Belt 4-Rib

The Dayco Elastic Self-Tensioning Serpentine Belt 4-Rib is a stretch-fit serpentine belt (also called a drive belt or accessory drive belt) that drives engine accessories such as the alternator, water pump, power steering pump and A/C compressor. It does not need a spring-loaded tensioner. The belt's elasticity keeps it tight on the pulleys.

Key Features:

• Elastic, self-tensioning design: The belt is installed by stretching it over the pulleys. This removes the need for a separate automatic tensioner assembly.
• 4-rib (4PK) profile: The multi-rib design matches the grooves of the accessory drive pulleys. It gives smooth, quiet power transfer.
• Dayco quality: Dayco is a long-established maker of drive belts and engine accessory drive components.
• Durable construction: The belt is built to resist heat, wear and cracking in normal engine-bay conditions.

A fresh belt helps keep accessories running reliably and cuts down on slippage and belt noise. Choose the variant that matches your application from the options on this page.
