Engineered specifically for 2017 through 2026 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.7L Powerstroke turbo diesel engine, this genuine Ford Motorcraft HVAC Heater Inlet Water Hose Assembly (HC3Z-18472-J / Motorcraft KH-867) supplies hot pressurized engine coolant from the primary cooling system manifold directly into the cabin heater core.

The redesigned 2017+ Super Duty engine bay layout subjects cooling and heater lines to extreme radiant heat generated by the top-mounted turbocharger and high-pressure exhaust manifolds. Over extended service, factory heater hoses experience electrochemical degradation (ECD), the interior rubber matrix hardens, and the composite quick-disconnect couplers become brittle. A failing hose causes sweet-smelling coolant misting, loss of cabin heat, and sudden drops in primary system pressure. Replacing aged lines with authentic Ford part number HC3Z-18472-J guarantees factory sealing tolerances, eliminates kinking, and ensures long-term leak-free reliability.

Key Features & Benefits

• Genuine Ford OEM Component: Manufactured to strict Ford Motor Company quality benchmarks for exact fitment, zero chafing, and dependable sealing.
• Pre-Assembled Quick-Connect Fitting: Equipped with the factory-style quick-disconnect coupling for a positive-locking, leak-free seal onto the heater core bulkhead.
• Pre-Formed Molded Contour: Precision-bent rubber routing clears engine bay wiring harnesses, fuel lines, and heat shielding without binding or kinking.
• Heat & Chemical Resistant EPDM Formulation: Heavy-duty reinforced synthetic elastomer resists internal micro-cracking and chemical erosion caused by modern OAT/HOAT coolants.
• Solves Engine Bay Coolant Seepage: Permanently replaces fatigued rubber and flattened internal O-rings that lead to mystery coolant loss.
