Raptor getting hot, supposedly. Mechs on here?

On a serious note, issues like that are enough to piss a guy off! Typically turns out to be something stupid though. Best of luck
 
Self-igniting models! :ROFLMAO:

Mine is just an SVT performance version of the same Boss 6.2 V8 that had been Ford's HD motor for years, uses all the same proven cooling parts.

well there’s your problem. You really just need a good ole 300 In-line 6. Mine has been running fine for about 50 years.

yes...nothing over 185* anywhere including the radiator, but idling. Can't reproduce the issue in the driveway or even tooling around.

Well that’s good your definitely getting good flow, mine sits around 204-210 this time of year.
Have you checked your cooling fan motors and fan clutch ?

A lot of times the fans will get stuck on low which is fine for most driving, but won’t switch on to high when your putting load on the engine.

just throwing this out there. i had a sierra with the 6.2 ( i know different manufacturer) however in the dead of summer towing our camper to utah it would get hot going up grades. it even had the tow pack radiator, but it was still the same one from the small motor trucks. long story short the manufactures dont spend money most of the time to re engineer a part that will do fine for 98%. i ended up going to an aftermarket cold case and never had the issue again. not saying its your issue but i sounds very similar. truck always ran at temp doing anything else but towing in the summer would creep the temps up to the point i discolored my entire exhaust pipe from manifold to tip. more rpms made it worse as well as it was not giving the coolant time to cool in the radiator.
 
Red Rock repair on W. Charleston, they are great, honest mechanics

Actually...took it there. They had it a day and 6 hours of labor declared the truck healthy, nothing wrong with it.
I sent it down the road a week later, deer hunt was coming.

WOW, they do all the work on my Roush and Bronco, plus my company trucks. They have always come through for me.

They were the third batch of mechanics to reach that conclusion, was time to cut my losses.
 
Check for partially clogged cats. Just a thought.
Temps would be ok at idle and normal driving. Put your foot in it and the exhaust will start to back up and everything gets very very hot.

They tested fine, bought the gauge and did the before and after thing myself.
The truck easily passed inspection at the dealership that got it, the new one pulls my little trailers like a champ.

Well it looks like everyone covered most of the bases. What does a secondary gauge say when the temp gauge goes up while towing? Forgive me if you already mentioned it but does the scanner data match the temp gauge on the car? Depending on how much you are towing it may just need a cooling system upgrade. Would a different tune help it run cooler? If the condenser isn't restricting air the only other things I can think to check are any factory shrouds the help air go through the radiator and not elsewhere.

It's not my problem anymore, I surely miss that truck but not the issue while towing....talked to a very good mechanic not long ago who is convinced that it had exhaust valve or valve spring trouble in the head that the cylinder head temperature sensor threaded into.
That exhaust gas was heating up only that head..explains how it could heat and cool according to the gauge and laptop so fast without actually overheating the coolant..his theory. Meh, Mopar now.

I understand from previous postings that the truck was sold a few months ago.

In September yep, it's out of state somewhere. The DMV thinks I still have it too, told them I don't but still....
