What are considered Safe Temps when towing on a 6.4??

[ThirdCoastStroker]

Alright guys you can see my mods in sig, just intake, tuner, exhaust,
im just wondering about some safe temps when towing.
I will be making some fairly long trips towing some boats coming up soon and its not really that they are all that heavy but the catch a ton of air which will put a good load on, this is what i am at runnning 70 down the highway, mind you that the ambient temp out here is anywhere from 94* to 105*

EOT - 203-205
ECT - 197-199
Trans - 173 give or take a few *

what is a safe setting to set my mini maxx to defuel at?
if i hit 220* with my oil when towing is that something to worry about?

I run the same tune, 4" exhaust, and an S&B intake, I have my #1 pyro set to defuel at 1450, everything else set at "stock" defuel. I frequently tow around 12k. Our ambient temp's get that high once in awhile up here, but not too often. I travel at about the same speed, and usually hilly grades... Haven't had any issues.

Im not worried about EGT's really i know what to look for on those, im just wondering about oil temps and coolant temps

I just pulled my 9600lb 5ver over Donner Summit, 7200ft this last weekend and seen 219 EOT 219 with ECT 213. The fan never came on and the dash temp was only a little past the middle. I figured if that if was to hot Ford would have set the fan to engage at that temp.

Anyone else out there have any input on this?

My Edge Insight CTS alarms when the oil temp hits 225 degrees. Came set that way from the factory. It alarms and I back off on the throttle.

does h&s have any tunes like the spartan 210 and under that have built in safety's for temps and what not? if so i would say run those well towing and then jump back to the 300 when not towing. seeing how it's easier to switch tunes on the h&s

you know you can go into the settings, and set your defuel levels, so when any of your temps hit what not it will auto defuel your truck

my truck has gotten all the way up to 240 when towing heavy before and the tranny temp gauge didnt move past the little gear symbol so like you said before if ford thought it were too hot im sure that it would have been in the red if it were. it never even reached the yellow and that was getting to the top of a long steep hill when it was 107 out.

I'm worried about my temps. Just cruising unloaded they are fine. Never more than 6 degrees apart. But when towing @ 70 with 6k my oil hovers at 217-220 and coolant at 203-205. Do I have an oil cooler issue? I just flushed the ford garbage from my radiator and went with cat elc. Are these temps normal? 95 degree ambient with the only elevation changes being over passes. Running 210 tow (Spartan) s&b intake, everything else stock.
