Detailed Description

The Gates Molded Coolant Hose line is built for vehicles that use a shaped coolant hose assembly rather than a universal straight hose. Part number 23674 is manufactured for specific Ford and Lincoln cooling system layouts and includes an integrated quick-connect fitting to match the original connection style. This makes it a practical replacement for lower radiator hose service on 2010-2019 Ford Flex, 2010-2017 Ford Taurus, 2018-2019 Ford Taurus, 2010-2019 Lincoln MKT, and 2010-2016 Lincoln MKS applications.

This hose is designed around the factory routing and dimensions, including a 15.5-inch centerline length and 1.48-inch inside diameter at both ends. If you are replacing a molded coolant hose on a Ford Flex or Lincoln MKT, Gates 23674 provides the correct shape and connector style for the listed applications. This part cross-references Four Seasons 66545 for the same application.

Common Cooling System Issues It Can Address

• Cracked or leaking lower radiator hose
• Damaged quick connector at the radiator-to-connector connection
• Coolant seepage from an aged molded hose assembly
• Improper hose routing after a failed replacement part
• Cooling system service on Ford Flex, Ford Taurus, Lincoln MKT, or Lincoln MKS models

Installation Notes and Tips

Verify the vehicle year, engine configuration, and lower radiator-to-connector routing before installation. Compare the original hose shape, connector style, and end diameters to Gates 23674 to confirm the correct application for your Ford Flex, Ford Taurus, Lincoln MKT, or Lincoln MKS. Inspect mating surfaces and adjacent cooling system components for wear before installing the new hose.
