Gates CO34957 engine coolant water outlet for the 2008-2010 Ford F-250 Super Duty V8 6.4L and other vehicles covers the thermostat and sends coolant out of the engine. It is designed to fit and perform like the original and to give long service life.
Coolant stains or crusty residue around the thermostat cover, or a cracked or corroded cover, can mean the outlet is leaking. Before you replace it, look over the cover and seal joint with the engine off and cool; a nearby hose or clamp can leak in the same spot.
The 2008-2010 Ford F-350 Super Duty V8 6.4L and the 2008-2010 Ford F-450 Super Duty V8 6.4L both take this outlet, and more vehicles do too, one outlet each. Open the "Vehicles it fits" section to check your exact model and engine.
