2004 F250 6.0L Fan Overheat

    So I am having an issue while driving around with my 8600HD on my 2004 F250 Powerstroke. While driving around with the plow all the way up, I hear the fan speed up immensely and it is louder than the engine. I experience this for a little while then it goes away. Today I had the plow on before some snow here in NE and its just about at freezing. I had it up for about an hour and I experienced this issue. I have heard that the new Plow Prep Package fan clutch may solve this issue as well as adding the Blizzard Airfoil that directs air into the radiator. Ant other info is appreciated.

    Thanks!!

    ??? Did temp gauge show overheat?

    That sound it normal they are supposed to be sound like airplane/jet. ROAR when fan engage

    If you are very concern about overheat. You could do flushing cooling system and replaced with ELC red coolant and new theromstat.


    Green or gold coolant aren't good for 6.0L they the #1 issue that ruin 6.0L reputation.

    The gauge didn't show it was running Hot at all. I will have to get fluids this week and do a flush.

    Sounds good. I have a ScanGauge2 on order to monitor my temps because i'd like something more straight forward than the idiot lights.

    Aslo, the sound of a Mack truck coming from my engine bay concerned me.

    Fan clutch is bad, get it replaced soon.

    OK. So I need an answer as to if it is GOOD or if it is BAD. IF it is bad, I need to replace it. IF NOT, I need to leave it alone.

    I highly doubt that the issue is your fan clutch. With the plow off the truck does it still come on more than it ussed to? Scan it and see what the engine oil temp is when fully warmed up after driving around and what the coolant temp is. If it is only with the plow fully up when driving that is normal on most vehicles try lowering the plow to only half way up and see if that helps.

    The other day I hooked my friends Snap-On Solus Pro up to the truck and EOT was 171 while ECT was 172. The threshold is a 20 degree difference between the two until I should be concerned about an Oil Cooler failure or other issues. I have not experienced it with the plow off.

    BTW. Those temps were at normal highway driving after the truck was running for about 1.5 hours also.

    you are running cold. normal is 192F temp spread is not accurate until you are at 'normal' operating temps. I would suggest a new thermostat and see what happens then.

    Is the thermostat off the upper radiator hose on the engine?
