Help keep hot coolant moving through your heater circuit with the Dorman heater hose assembly 626-642, a direct-fit replacement for the 2011-2014 Ford Expedition and 2011-2014 Lincoln Navigator. This outlet-side assembly comes from Dorman's OE FIX line and targets a known weak spot in the original design.
Original equipment heater hose assemblies often fail when the plastic Y-connector cracks. This Dorman hvac heater hose assembly replaces it with an upgraded aluminum Y-connector, designed to help avoid a repeat of that failure.
- Upgraded material: aluminum Y-connectors for added durability.
- Application specific: designed to match the original heater hoses' fit and function on the listed vehicles.
- Complete replacement: the hoses ship with the necessary clamps for easier installation.
- Quality engineering: designed in the United States and backed by Dorman's decades of automotive aftermarket experience.
As the outlet heater hose, this assembly carries engine coolant on the outlet side of the heater circuit. Signs a heater hose may need replacing include coolant drips or puddles, a dropping coolant level, a sweet coolant smell, or weak cabin heat. Diagnose the cause first. If a cracked Y-connector or leaking hose is to blame, this assembly is a straightforward choice for a 2011-2014 Ford Expedition heater hose replacement.
