06 getting hot while towing

[BLACK_PSTROKE]

as title mentions. my dad just called me and said when he is pulling his 5th wheel the truck gets hot and pukes. said it only happens when he is pulling. empty everything seems fine. truck only has afe intake and 4" exhaust. no tunes
any ideas???? on a side note hes been to a dealer several times they keep saying the egr valve is bad so they put in a new valve. and tell him its because of the intake and the cat-less exhaust????

I am thinking EGR cooler but I could be wrong.

On a side note I would try another dealer, Intake and exhaust will not make the truck overheat.

thats kinda the idea i been having also i think thats been the problem for awhile. they just keep putting in new valves

Find a new dealership fast and never return to the one you're referring to... They're idiots.

My guess is it's a head gasket. If it was the EGR cooler it should be puking when unloaded also.

that really sucks. the worst part about it is he is having to go over the mountains to get back to indiana.

Like I said that's just my guess. Could be other issues too, but that's my guess.

could be several things..start out with an oil cooler rebuild kit and a EGR delete, see what happens after that, if it continues to puke, probably a blown head gasket.

i think better start out with getting the headgaskets checked because its still under warranty and not tuned. but egr delete is definetly gonna be closely followed. thanks for all the quick input guys

Is it overheating on flat land or in the hills?

Ford protocol is to datalog EOT vs ECT prior to headgasket replacement. Most dealers will replace the oil cooler and EGR cooler before jumping directly to headgaskets. If those to items do not fix the puking issue, the tech will get approval to do headgaskets.
