How to service the thermostat for 4.6L, 5.4L, and 6.8L engines on Ford E-250?

Service of the thermostat requires draining the engine cooling system for all 4.6L 5.4L and 6.8L engine types. The next step entails disassembly of the air cleaner outlet pipe. Service providers must disconnect the upper radiator hose before working on the thermostat housing. Begin by unfastening the two bolts from the thermostat housing and placing it to the side then extract the thermostat along with discarding the O-ring seal. The packaging instructions guide the user through metal surface prep procedures that they need to perform on the sealing surfaces. Secure the new O-ring seal in the housing before torquing the bolts to 25 Nm (18 ft. lbs). The engine cooling system filling and bleeding procedure begins after the reinstallation of components when completing the removal process.
