• Other Names:

  Tube Heater Water, KT158

• Description:

  This genuine Ford heater water tube carries engine coolant to and from the heater core as part of the cabin heating and HVAC circuit on Ford E-Series vans. As a formed metal-and-hose assembly, it routes hot coolant from the engine to the heater core so the blower can deliver warm air to the cabin, then returns it to the cooling system; the routing also helps purge air and maintain flow through the heater loop. It fits 2001-2019 Ford E-150, E-250, E-350 and E-350 Super Duty, and E-450 Super Duty across 4.6L and 5.4L V8, 6.8L V10, and 6.0L and 7.3L Power Stroke diesel engine applications. Ford catalogs this component as Tube - Heater Water. A buyer typically needs this part after finding a coolant leak, dripping, or steam near the firewall or engine, a sweet coolant smell, weak or no cabin heat, fogging at the windshield, or gradual coolant loss with an overheating tendency, all of which point to a corroded, split, or leaking heater tube or its connections. Replace it with the cooling system cool and depressurized, refill with the correct Ford-specified coolant, and bleed the system to remove trapped air so the heater core receives full flow. Check the O-rings, clamps, and quick-connect fittings during installation and confirm there are no leaks after refilling. Using the genuine OEM tube ensures correct fit, corrosion resistance, and sealing for a lasting repair.
