Detailed Description

Gates 23784 is a molded radiator coolant hose engineered for lower hose routing on the Honda Pilot and Honda Ridgeline. Its EPDM construction and molded shape support a factory-style path through the engine bay, helping maintain proper coolant flow where a straight hose would not match the original routing. If you are replacing a worn lower hose on a 2009-2015 Honda Pilot or a 2009-2014 Honda Ridgeline, this part number 23784 provides the correct molded profile for the application.

This part cross-references Dayco 72562 and Four Seasons 66349 for the same application.

Common Repair Uses

• Cracked or hardened lower radiator hose
• Coolant seepage at the hose body or ends
• Collapsed hose from age or heat cycling
• Incorrect routing after prior cooling-system repair
• Replacement for a damaged molded hose on Honda Pilot or Honda Ridgeline models

Installation Notes and Tips

Verify the hose routing against the original part before installation. Inspect hose clamps, mating necks, and nearby cooling-system components for wear, corrosion, or residue before reassembly. Confirm the hose is seated fully on both ends and routed without twist or contact with hot or moving parts. For best results, replace coolant as needed after completing the repair.

Quality Assurance

Gates molded coolant hoses are manufactured to OEM-quality specifications for replacement cooling-system service. The molded design, EPDM material, and application-specific dimensions support consistent fitment on the listed Honda Pilot and Honda Ridgeline models.
