Product Details

This Gates Molded Coolant Hose line is built for replacement use where a formed hose is needed to match factory routing. Part number 20686 is listed for a wide range of vehicles, including 1970-1975 Chevrolet Camaro upper radiator hose applications, 1983-1985 Cadillac Fleetwood lower hose applications, and 1970-1973 Ford LTD upper hose applications. It also cross-references Four Seasons 20686 for the same application.

For buyers searching for a molded upper radiator hose for a Chevrolet Camaro, a lower coolant hose for a Cadillac DeVille or Fleetwood, or an OEM-style heater hose replacement for older GM and Ford platforms, this part number provides a direct-fit solution where the original hose shape matters. Gates 20686 is part of the Molded Coolant Hose product line, which covers a broad range of cooling and HVAC hose replacement needs.

Common Problems This Hose Can Address

  • Cracked or hardened coolant hose material
  • Leaks at the radiator hose connection points
  • Collapsed or misshaped hose routing
  • Incorrect fit from universal cut-to-length hose
  • Cooling-system service on aging classic vehicles

Installation Notes and Tips

Verify end diameters, centerline length, and routing before installation. Compare the molded shape to the original hose on the vehicle to confirm upper or lower placement, especially on applications such as Chevrolet Camaro, Cadillac DeVille, and Ford LTD. Inspect clamps, necks, and adjoining cooling-system components for wear before installing the new hose.

Quality Assurance

Gates manufactures this molded coolant hose to OEM-quality specifications for replacement cooling-system service. The EPDM material and molded construction are selected for radiator and heater hose applications where factory-style fit and routing are required.
