Detailed Description

Gates 20957 is a molded radiator coolant hose with a 1.75-inch inside diameter at each end and an 18.2-inch centerline length. The EPDM material is commonly used in cooling-system hoses for its resistance to heat and coolant exposure, while the molded profile supports proper hose routing in vehicles that require a formed replacement rather than a universal straight hose.

Compatible With applications include 1985-1992 Dodge B250 and B350 lower hose positions, 1989-1991 Dodge D250 and D350 upper hose positions, 1972-1979 Ford F-100 and F-350 lower hose positions, and 1967-1969 Chevrolet Camaro lower hose applications. It also covers additional classic Dodge, Ford, Chevrolet, Cadillac, Chrysler, Pontiac, and Plymouth fitments listed in the vehicle table.

This part cross-references Four Seasons 20957 and Roadmax C0957 for the same application.

Common Problems This Hose Can Address

• Cracked or hardened radiator coolant hose material
• Coolant leaks at a worn upper or lower hose
• Poor hose routing from an incorrect universal replacement
• Heat-related swelling or collapse in an aging hose
• Service issues on vehicles requiring a molded hose shape

Installation Notes and Tips

• Verify the hose position, inside diameter, and centerline length before installation.
• Match the molded shape to the original routing on the vehicle.
• Inspect clamps, necks, and adjoining coolant components during replacement.
• Confirm whether the application is upper or lower, since fitment varies by model and year.
• For cut-to-fit applications noted in the fitment data, trim only as required by the vehicle listing.
