Gates 20364 Molded Coolant Hose Overview

The Gates 20364 molded coolant hose is built for radiator coolant routing in upper and lower cooling system applications. Made from EPDM and formed to OEM-quality specifications, it provides a direct replacement option for select classic Chrysler, Dodge, and Buick applications.

  • 1.56 in. (40 mm) inside diameter at both ends

  • Direct replacement part number: 20364

Detailed Description

Gates 20364 is a molded radiator coolant hose engineered for vehicles that require a formed hose profile rather than a universal straight hose. The hose is listed for upper and lower positions depending on application, with fitment covering 1953-1972 vehicles and notes that include standard cooling, non-AC configurations, and select applications that require trimming to fit. Confirmed fitment includes 1971-1972 Chrysler New Yorker upper, 1971-1972 Chrysler Newport upper, 1971-1972 Chrysler Town & Country upper, 1971 Chrysler 300 upper, 1969 Chrysler New Yorker upper, 1969 Dodge Charger upper, 1963-1965 Buick Riviera lower, and 1954-1956 Buick Century lower.

This part cross-references Dayco 70352 for the same application.

What It Helps Fix

  • Cracked or hardened radiator hose material
  • Coolant leaks at a formed hose section
  • Poor hose routing from an incorrect straight hose replacement
  • Fitment issues on classic Chrysler, Dodge, and Buick cooling systems
  • Service delays when an OE-style molded hose is needed

Installation Notes

Verify end diameters, centerline length, and hose routing before installation. This Gates 20364 molded coolant hose is listed for specific upper and lower applications, and some fitments note non-AC, standard cooling, or trim-to-fit requirements. Match the vehicle’s cooling layout and confirm clearance around radiator, heater, and HVAC components before final assembly.

Quality Assurance

Gates manufactures this molded coolant hose to OEM-quality specifications using EPDM construction for cooling system service. The Gates molded coolant hose line is built to cover a broad range of replacement applications across radiator, heater, bypass, and other coolant hose needs.
