Engine Fans running constantly
Have an 2006 350 with 6.0.
Truck was fine. Sat without running for 10 days.
Now the fans run all the time as if the engine is hot. I dont mean the fans turn I mean they roar when your driving like they do when they kick in on high engine temps. Doesnt matter what the engine temp is they run pulling out the driveway when truck is cold and they stay on. I have not driven the truck for a longtime in this condition so I dont know what will happen if I get it up to high temp.
No codes shown through SCT device.
There is no tune on the truck.
I have been trying to do most repairs on this truck myself and learning as I go.
Need some diagnostic ideas.
Thanks in advance.
