04 excursion 6.0 problem

My first diesel. 04 excursion 6.0 stock. Cooling fan coming on and off while driving. Heat blows hot until fan kicks on and then turns cold. Fan turns off heat hot again. Could this be thermostat getting ready to g? Fan clutch? Both? Any other suggestions or where I should start will be appreciated. Thanks.

Fan is coming on because your engine is overheating. The gauge on the dash is an idiot light. Once it shows hot it's too late. This is why a monitor is essential in a 6.0l.

So change thermostat and check coolant? Also fan will sometimes stay on from start up. Thanks for reply!

Well if it's coming on full speed at initial startup then maybe your fan clutch is going bad.

OK thanks. Maybe I'll change both because I don't understand how fan clutch would after heat though? Thanks again.

There may be air in the cooling system due to failed headgaskets causing heater to blow cold air
