Product Details

Gates 23938 is a molded lower coolant hose for vehicles that require a shaped replacement rather than a universal cut-to-fit hose. The EPDM material is selected for radiator hose service, while the molded profile helps maintain the original hose path and connection points. This part cross-references Monroe Shocks & Struts (e.g., 16603, 22740M) for the same application.

Gates 23938 is also a practical search match for molded coolant hose replacement, lower radiator hose replacement, and OEM-style cooling system repair.

Common Problems It Can Address

• Cracked or split lower radiator hose
• Coolant leaks at the hose body or ends
• Collapsed or softened hose material
• Incorrect fit from a universal hose
• Loss of factory hose routing shape

Installation Notes and Tips

Confirm the vehicle application, position, and hose routing before installation. Compare the original hose length, end diameters, and molded shape to the replacement part. Inspect adjoining clamps, necks, and coolant passages for wear or corrosion before refilling the system.

After installation, refill and bleed the cooling system according to the vehicle service procedure and check for leaks at operating temperature.
