Product Details

Gates Molded Coolant Hose line is built around OEM-quality specifications for radiator hose replacement across upper, lower, bypass, heater, and other coolant routing needs. Part number 20476 is a molded EPDM hose with a 1.25-inch inside diameter at each end and an 11.3-inch centerline length, making it a direct-style solution for vehicles that require a formed hose shape rather than a universal straight hose. This part cross-references Dayco 70817 for the same application.

Compatible vehicle coverage includes Fits 1999-2002 Suzuki Esteem, lower; Fits 1982-1986 Buick Skyhawk, upper; Fits 1982-1986 Oldsmobile Firenza, upper; Fits 1986 Pontiac Sunbird, upper; Fits 1984-1985 Pontiac J2000 Sunbird, upper; Fits 1982-1983 Pontiac J2000, upper; Fits 1966-1967 Pontiac Acadian, upper; Fits 1962-1964 Pontiac Acadian, upper; Fits 1965 GMC G1000 Series, upper.

Common Problems This Hose Can Address

  • Cracked or hardened radiator hose material
  • Coolant leaks from a worn molded hose
  • Poor hose routing caused by an incorrect straight hose
  • Replacement needs on upper or lower coolant hose locations
  • Fitment issues when the original hose requires a formed profile

Installation Notes

Verify the vehicle year, make, model, and hose position before ordering. This hose is not listed for vehicles equipped with AC on the Buick Skyhawk, Oldsmobile Firenza, Pontiac Sunbird, Pontiac J2000 Sunbird, and Pontiac J2000 upper-hose applications shown above. Confirm end diameter and centerline length against the original hose before installation, and inspect clamps, necks, and adjacent cooling components for wear or corrosion.

Quality Assurance

Gates manufactures this molded coolant hose to OEM-quality specifications for replacement use in the cooling system. The molded EPDM construction and application-specific shape are intended to match the routing requirements of the listed vehicles, including select Suzuki Esteem, Pontiac, Buick, and GMC applications.
