Towing and Cooling
While pulling the new fiver through Tennessee the other day, I noticed the temperature gauge swinging rapidly back and forth from 1/2 to 3/4. Flipped the display to gauge mode and found the oil temperature at 242. I never heard the engine cooling fan engage.
Took the truck in for service yesterday and asked them to check the cooling system and got the standard answer - "We found no codes. Towing will cause the temperatures to increase."
They did the NOX sensor recall and said that should help with the cooling. WHAT? HOW?
Guess next time, I'll take a video of the gauge and then ask them if that's "Normal while towing."

240 has been reported before but your fan should probably have come on.
If I remember right, there is no code thrown for a faulty fan clutch but there is a test for it. I could be wrong, but seems like I remember this before.

I find that on my F-450 the oil temp rises considerably with increased RPM. Since you are running 4.30 rear end you are turning more RPM than most members here who are running probably 3.31 or 3.55. I think it is reasonable to run a synthetic oil, but I also do not recollect hearing my fan come on.

242° is pretty common Oil temp if you are towing, Especially heavy rigs or steep grades.
Back when these trucks first came out we asked some questions about it and the report back from the Ford Engineers was this was within tolerances.
So I wouldn't worry about Oil temps unless they went over that number.

I never noticed it again through the mountain passes of Idaho and Washington.
