Sorry - I didn't read post #5 (and I was writing #14 when you posted #13). Tobacco farmer may have you covered, but the early model years were more prone to water pump failures than the 05's and up.

I'm interested to see what you problem is. Mine is doing the same thing. I changed my thermostat with a NAPA replacement about 80000 ago so maybe it crapped out on me. Mine only does it when pulling hills at 80 mph or so. It pukes as well and I have headstuds and a egr delete so it sounds like we have the same problem....good luck

well the next morning after changing the thermostat it overheatd AGAIN on the way to work driving at about 65mph so i turned off the truck and put it in neutral and let it cruise like that for a little bit, didnt come to a complete stop then turned it back on and the temp slowy came back down to normal. Andthis afternoon i just took a 2hr trip home driving like at about 80mph most of the way and didnt experience any problems at all!!!!and i kep driving it like i stole it and still no overheating, this is a very random event i cant figure it out!!!
....is there a way to check if the water pump is bad without tearing into it????help and thanks for all the replies

Warranty....I wish!
Nope, 133,000 miles. Trying the simple stuff first before I dive into the big items such as EGR/Oil coolers. Ultimately, I believe I'll have to go there. If only it will hold out until the 6.7L hits the streets.
