Dorman - OE Solutions HVAC Heater Hose Assembly P/N:626-626
Help keep hot coolant moving through the heater circuit with this DORMAN heater hose assembly, part number 626-838, a direct-fit replacement in the inlet position for the 2015-2017 Ford Expedition and 2015-2017 Lincoln Navigator. It is part of Dorman's OE FIX line. Original equipment assemblies often fail when their plastic T-connector cracks, so this version uses an upgraded aluminum T-connector intended to address that failure.
If the heater hose on your 2015-2017 Ford Expedition is seeping coolant, shows a cracked T-connector, or the cabin heat has turned weak, the inlet hose assembly may need replacing. Diagnose the cause first, because other cooling-system components can produce the same symptoms. Engine details for each vehicle are listed in the "Vehicles it fits" section.
