I've heard a good bit about the 6.0 overheating, unfortunatly I have now experienced this with my 42,000 mi 04 F450. We are succesfully maintaining 4 other vehicles(most over 100,000mi) in the company and weekly checking fluids. The failure occured as we were going down the interstate, all things normal then there was a woosh, a puff of smoke came out of the exhaust. No check engine light or high temp. reading visible,and that is all she wrote.
Ford keeps chanting negligence because we didn't notice the nonexistant cloud of smoke associated with an overheating(470F is what they tell me) engine. After a month of waiting to talk to an almighty ford rep. the best reply to my questions i could get out of him was "I'm not an engineer so i can't answer that question"
Can anyone give me a straight answer as to why a perfectly good truck would mysteriously overheat?
Maybe you should ask Ford about the basically non-existant temperature gauge in the truck that only tells you it's hot after it's too late. My gauge never showed hot until the fan came on and it took 3 gallons of coolant to fill the truck back up to get it home. FWIW--the gauges are only dummied up glorified idiot lights at best. I don't know what the temp gauge "normal" temp. reading is, but I know it only takes 7 1/2 lbs of oil pressure to make the oil gauge read "normal". Keep reading the forum and you'll find some ammunition to fight with.

You probably have a catastrophic failure at this point. But here is an article that demonstrates the cooling system challenges in turbodiesels, from an engineer.KILLERBEE
I know the engine got very hot for several reasons 1) when i popped the hood it was unusually hot 2)i pulled the oil dip stick and you could see that it got unusually hot (once the oil settled the level was still at the full mark) 3)no fluid in the radiator 4)the Ford mechanic said that there is a plastic pipe in the filter that will melt if the temp. is over 470 F. I haven't seen this yet but that is what they tell me. Thanks so much for your reply.
When my 06 would run hot I got a check gauges signal on the little LED odmeter display.
When I got the normal to gushing white smoke problem without it running hot was when the EGR cooler went bad, fortunetly, the engine didn't get hot as I noticed it coasting down hill when it went.
it seems to me your local dealership is giving you the run around.
It's true about the stand pipe in the oil filter housing. I've seen one melted, but it was from an irresponsible driver who knew the motor was toast and kept driving.
