Product Details

This Gates molded coolant hose is part of the Molded Coolant Hose line, which focuses on application-specific modular assemblies that mirror OE-style layouts and integrated components. Gates 23671 is built for vehicles that use a lower radiator hose with a quick-connect interface, helping maintain the original hose path and connection style on the cooling system. It is a direct replacement choice for Ford Expedition, Lincoln Navigator, and select Ford F-Series applications listed in the fitment data.

This part cross-references Dayco 72640 and Bosch 66172 for the same application.

What It Helps Address

• Coolant leaks from a cracked or aged lower hose
• Softening, swelling, or collapse of the original hose
• Damaged quick-connect connection points
• Improper hose routing after cooling system service
• Cooling system maintenance on Ford Expedition, Lincoln Navigator, and Ford F-150 models

Installation Notes

Verify the vehicle year, make, model, and lower hose position before installation. Inspect the mating connector, clamps, and nearby cooling system components for wear or contamination before transferring the hose into service. Confirm that the hose follows the original routing and that the quick connector seats fully at the connection point.
