Serpentine Belts

Manufacturers like Gates, Dyco Provides Premium Quality Serpentine belts, Serpentine Belt is a V-ribbed belt that is ribbed along one side. It’s much thinner than a drive belt in appearance. It bends easier and is much more flexible which allows it move and wrap around smaller accessories inside the engine. A Serpentine belt lasts longer than traditional drive belts and is much easier to remove and install. This belt also transmits power between the steering pump, alternator, water pump and air conditioner compressor.

Dayco approaches the market differently from most of its competition, believing that one serpentine belt construction will not perform best with all applications.Built for passenger cars and light-duty trucks, Dayco’s extensive line of Poly Rib serpentine belts are engineered for high mileage, demanding drives found in today’s vehicles. As the manufacturer of the first original equipment multi-ribbed serpentine belt, Dayco’s commitment to automotive product excellence and innovation is unwavering. The Dayco Poly Rib W Profile serpentine belt is the most innovative advancement in serpentine belt design in more than 30 years. Developed through extensive laboratory and actual road mileage testing, this unique rib profile EPDM belt has been engineered to conform to high mileage, worn or misaligned drives and help eliminate noisy belt conditions. Constructed with aramid-reinforced EPDM compounds, the Dayco W Poly Rib serpentine belt delivers more than just OE-required quality. It delivers the solution to troublesome drive problems. Dayco manufactures other serpentine belt constructions for application-specific belt drive systems, such as the ela stretch belt, special deep rib belts for certain import applications, Linear Groove Technology belts and double-sided belts. ela Stretch belt – Designed for direct replacement on accessory drives requiring stretch-type belts, Dayco ela belts are specifically designed for two- to four-point drives where the elastic belt design maintains constant tension on the drive. Deep Rib belt – Dayco discovered that certain import applications perform quietest when the rib depth of the serpentine belt is increased. Dayco added layers of material, increasing the rib depth of the Deep Rib belt, resulting in the best drive belt option for specific import vehicle applications. Double-sided belt– Designed for multiple accessory drives that require the transmission of power from both sides of the belt. The Double-Sided belt, which Dayco introduced to the automotive aftermarket, features a construction that uses a highly fiber-loaded compound on both sides of the belt to maximize load carrying requirements while minimizing pulley misalignment noise.

Dayco No Slack Automatic Belt Tensioner

Serpentine belt drives consist of a single belt that powers most, if not all, of the engine’s accessories. Designed to maintain constant tension on serpentine belt drives, the Dayco Automatic Belt Tensioner features the original flat spring design engineered to provide less operating range variations in tension. This innovative design reduces the risk of premature accessory bearing failure due to high tension when a new belt is installed and lessens the risk of belt noise and slippage, or poor accessory performance caused by low tension after the belt begins to stretch and wear. A PTFE strip wound within the spring resists abrasion and the flat spring is coated to resist rust.
Other superior design features include:
* Steel locator pin (where the application demands)
* Heavy duty cast aluminum spring case that resists cracking and fatigue
* Heavy duty cast aluminum arm offers additional strength and less distortion
* Steel pivot tube (where the application demands) provides additional strength for critical torque requirements
* Thermoplastic rubber spring slot plug (where applicable) helps keep out harmful contaminants
* Lubricated nylon pivot tube bushing and spring bushing for quieter performance
* Rubber “O” ring which seals against dust and grime (where applicable)
* Zinc-coated mounting bolt that resists rust (where applicable)
* Dayco also manufactures a variety of round spring and hydraulic-controlled tensioners depending on the original equipment design and application requirements.
