2004 Ford F-150 Heritage Thermostat Parts Q&A
Q: How to service the thermostat for 4.6L and 5.4L engines on 2004 Ford F-150 Heritage?
A: Serving the thermostat on 4.6L and 5.4L engines starts with draining a portion of the cooling system fluid. First disconnect the upper radiator hose then remove the water outlet connection by unbolting it. The water thermostat service requires removal followed by discarding the O-ring seal. Position the water thermostat in the upper intake manifold using a fresh O-ring seal before reinstallation of the water outlet connection together with its bolts. Install the upper radiator hose before filling the cooling system with its contents.
