  Hose Assembly, KM7718

• Description:

  This is the genuine Ford connector hose, the engine coolant hose that carries coolant between the cooling circuit components to keep engine temperatures within the correct operating range. Cataloged by Ford as a hose assembly, it routes coolant through the engine, heater, and auxiliary cooling paths so heat is carried away from the engine and released through the radiator. It fits the 21-23 F-150 with the 3.3L engine and related cooling configurations. Owners look for this hose when the original has developed a coolant leak, split at a connection, bulged or softened from age and heat, or begun weeping at a quick-connect fitting. Because it is a molded line exposed to constant heat cycling and engine vibration, the rubber can harden, crack, or lose its seal over time. A failed coolant hose can cause overheating, coolant loss, and steam or drips under the vehicle, all of which risk engine damage if ignored. As a genuine Ford part it is molded to the correct shape and length with factory connectors so it routes cleanly and mates securely without leaks. Installing the correct hose restores a sealed cooling circuit and reliable temperature control. Confirm the engine and routing against your vehicle before ordering, since Ford uses several coolant hose variants on this platform.
