2004 Ford F-250 Super Duty Thermostat Parts Q&A
Q: How to service the thermostat for the 5.4L and 6.8L engines on 2004 Ford F-250 Super Duty?
A: The first step to service the 5.4L and 6.8L engine thermostat includes draining part of the cooling system fluid. First disconnect the upper radiator hose before removing the outlet connection by destroying its bolts. You should first discard the O-ring seal before you remove the coolant thermostat and its O-ring seal. The correct process for installing the coolant thermostat in the upper intake manifold includes using a new O-ring seal that must fit properly. Secure the cooling system outlet by attaching it to the upper intake manifold then install its connecting bolts. Reestablish the upper radiator hose before finishing the procedure by filling the cooling system.
