  • Dayco: A Global Leader in Auto Drive Systems since 1905

    From its humble origins as a garden hose supplier, Dayco has grown to become one of the world\'s leading manufacturers of essential engine products, drive systems and services for automobiles, construction, agriculture, and industry. For 111 years, Dayco products have been integral part of how people get from place to place, how goods are transported, and how infrastructure is built, which the company\'s core values of delivering its promises on time no matter the obstacles - driving it to success.

    A specialist in drive belts

    Dayco\'s manufactures serpentine belts for application-specific belt drive systems, ranging from passenger cars, trucks, snowmobiles, ATV, and lawnmowers as well as for agricultural and industrial use. These serpentine belts from Dayco are engineered for high mileage use in demanding environments commonly experienced by most vehicles today. Customers can choose from a variety of serpentine belt configurations, including stretch belts for accessory drive use, deep rib and linear groove belts for import and high performance applications, and double-sided belts for multiple accessory drives that require the transmission of power from both sides of the belt. In addition, Dayco also offers drive belts for other types of vehicles including ATVs, snowmobiles, and lawnmowers.

    Belt tensioners

    Designed to keep the serpentine drive belt at a constant tension, Dayco automatic belt tensioners have a classic flat spring design that is tuned for less operating range variations. This limited range significantly cuts down the risk of accessory bearing failure due to high tension, especially when replacing a new belt, and reduces the risk of slippage. The spring case and arm of the tensioner is made of heavy duty cast aluminum that resists cracking, fatigue, and distortion, while a steel pivot tube helps keep the tensioner together during critical torque conditions. A PTFE strip is also wound inside the tensioner spring to shield it against abrasion and coated with a rust-resistant finish. Other features include a heavy duty steel locator pin, lubricated nylon pivot tube and spring bushings, zinc-coated mounting bolts, and a thermoplastic rubber spring slot plug that helps keep contaminants out.

    Radiator hoses

    Aside from drive system components, Dayco also manufactures rubber coolant hoses for automotive uses. The hoses, which range from standard straight hoses to molded and flex hoses, are designed as a direct OE-compliant replacement for cars, light to heavy duty trucks, and SUVs. This direct-fit design makes Dayco\'s hoses as easy to install as factory hoses. And for durability, Dayco radiator hoses have a state-of-the art EPDM construction with knitted rayon reinforcement, blending strength and high resistance to oil, mud, and other contaminants without sacrificing flexibility. Each hose is also tested to withstand temperatures as high as 257 degrees and as low as -40 degrees Fahrenheit. Selected hoses are also compliant with SAE J20R4 and Type EC electro- chemical requirements.

    In addition to radiator hoses, Dayco also manufactures several types of speciality hoses for selected applications, including heater hoses, vacuum hoses, and anti-smog/PCV hoses. These specialized hoses are made of the same tough, leak-resistant EPDM material and tested to comply with various international quality and safety standards.
