Replace a cracked or leaking coolant hose with the Dorman heater hose assembly 626-541, an OE FIX part that swaps the original plastic Y-connector for a metal one. It fits many vehicles, among them the 2011-2018 Ford F-150 (V8-5.0L), 2011-2018 Ford Mustang (V8-5.0L or V8-5.2L) and 2011-2018 Ford Lobo (V8-5.0L), each using one hose. See the "Vehicles it fits" section for the full list.
This part is listed under two names, heater hose / radiator coolant hose. It is a molded three-branch assembly that installs in the upper tee-to-thermostat position. Original hoses in this spot often fail when the plastic Y-connector cracks, so Dorman's replacement uses a metal Y-connector designed to address that weak point.
- Upgraded Y-connector: a metal Y-connector takes the place of the original plastic one for added durability.
- Application specific: designed to match the original hose's fit and function on the listed vehicles.
- Ready to install: the hose comes with the clamps it needs.
- Quality engineering: designed in the United States and backed by decades of Dorman aftermarket experience.

Signs a hose like this may need replacing include coolant leaks around the Y-connector, cracks or swelling in the hose, and a coolant level that keeps dropping. If this hose is the source of the leak, 626-541 replaces it. Diagnose the leak before replacing parts.
