6.0 running Hot
 

Just had my 2004 6.0 King Ranch rebuilt after the oil cooler ruined the engine. Thought we had the over heating problem fixed until today. It has been 100 + degrees out but starting off pulling a load of hit a hill and need to ask a little more from the engine and there it goes. The fan comes on and if it is a long hill 1/2 mile or so , up goes the temp. If i can get the hill made and ease off the peddle she will coll down a little but the fan runs all the time when pulling.
It has been one expensive thing after another and i have been dealing with crap like this for over a year. Can someone please tell me why i can't get to stop running hot ?
