Product Details

Gates builds this molded coolant hose for vehicles that require a formed replacement rather than a universal cut-to-fit hose. The modular hose design is intended to match the original routing and include the integrated features needed for the application, helping maintain proper coolant flow path and connection geometry. For buyers searching for a Ford F-250 Super Duty coolant hose or Ford F-350 Super Duty radiator coolant hose, Gates 23818 provides the correct molded layout for the reservoir-to-radiator connection.

This part cross-references Continental 64589 for the same application.

Common Cooling System Issues It May Address

• Cracked or aged reservoir-to-radiator hose
• Coolant seepage at a worn hose section

• Restricted coolant transfer caused by a damaged hose path
• Fitment problems from using a non-molded replacement hose

Installation Notes and Tips

Verify the hose routing, end diameters, and reservoir-to-radiator position before installation. Inspect mating necks, clamps, and nearby cooling system components for wear or damage, and replace any compromised parts as needed. Confirm the hose is seated fully and routed without twist or contact with hot or moving components.
