Detailed Description

This Gates 23111 molded coolant hose is formed to follow the original upper hose path and maintain proper connection geometry in the cooling system. The EPDM material is commonly used in coolant service for its resistance to heat and coolant exposure, while the molded profile helps match the factory routing on the Lexus RX400h and Toyota Highlander. If you are replacing a worn or leaking upper radiator hose, Gates 23111 provides a direct-fit service part for the specified applications.

This part cross-references Continental 66920 for the same application.

Common Problems It Can Help Solve

• Coolant leaks from a cracked or aged upper hose
• Softening, swelling, or collapse of the original hose
• Improper hose routing after a previous repair
• Loss of coolant from a damaged radiator hose connection
• Service issues caused by a hose that no longer holds its molded shape

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length before installation. Inspect the mating necks, clamps, and nearby cooling components for wear or corrosion, and replace any damaged hardware as needed. Confirm the hose is seated fully and routed without twist or contact with hot or moving parts.
