Raptor getting hot, supposedly. Mechs on here?

Fogie said:
Did in order..thermostat, radiator, water pump, fan assembly, laptop and head/block test
Will idle and drive all day long no issues, pulling the trailer on grades where higher than normal temps would be expected, thats when problem manifests.

Did you use motorcraft parts? I’ve heard of aftermarket thermostats not opening enough, and aftermarket radiators clogging up. After a decent drive what temps are you getting on the upper, middle, and lower areas of the radiator
 
@Fogie My close buddy is one of the lead guys at Team Ford. He has a "mobile mechanic" side gig that he does on nights and weekends. If you need some help send me a DM and I will give you his number. You won't pay the typical dealer rates.

Good luck chasing gremlins

This is my last smack at the problem....Thanks, hopefully won't have to take you up on it but probably will. ??
 
Maybe hook up a mechanical temp gauge to bypass all the electronic BS and tell ya what its actually running at.

Just going to get that sensor changed and the wiring straightened out, get it back together. Will see what happens then, might just get one more part for it after that. ?
Ha!...just kidding. It's extremely low miles and paid for, worth getting straight.
 
??...maybe it has feathers where they aren't supposed to be?

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

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

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.

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.

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.
