Keep engine coolant moving through the heater core with the Dorman - OE Solutions heater hose assembly, part number 626-537, a direct-fit replacement for the 2007-2008 Ford Expedition and 2007-2008 Lincoln Navigator. Cataloged for the outlet position, this Dorman heater hose assembly addresses a common weak point: original equipment assemblies often fail because the plastic Y-connector cracks.
Dorman's OE FIX version replaces that plastic piece with an upgraded aluminum Y-connector, intended to help prevent the same failure from happening again. If a cracked connector is the reason for your 2007-2008 Ford Expedition heater hose replacement, this HVAC heater hose assembly swaps out the whole unit.
- Upgraded material: aluminum Y-connectors take the place of the original plastic for added durability.
- Application specific: designed to match the original heater hoses' fit and function on the listed vehicles.
- Complete replacement: the hoses come with the necessary clamps for easier installation.
- Quality engineering: designed in the United States and backed by Dorman's decades of automotive aftermarket experience.
Signs a heater hose may need replacing include coolant seeping from the hose or Y-connector, a coolant level that keeps dropping, and weak heat from the vents. Diagnose the cause before replacing parts. See the Buyer's Guide tab for engine details.
