Question Towing with bad oil cooler?

Alright guys, my oil cooler is starting to get clogged up again. I had it replaced at 79,xxx and I now have 106,xxx. So today I was towing around 15k over not so flat ground and ect varied 205-212 and eot was about 228-234. The highest the eot got was 239 and the hottest the ect got was 213, this was when I was going up a pretty long incline. On my way home I was running empty with no trailer and ect was 190-192 and eot was 206-208 going 70. So my question is, is it ok to tow with a bad oil cooler and is there a max temp for eot before I need to pull over? Im gona try to get a new one here in the next few weeks hopefully. Thanks in advance for your help guys!!

Does that have to be reset after a new oil cooler is installed?

x2? and what about if you go aftermarket cooler?

Also it seems like a lot of people aren't liking the new flash but I read when looking to buy one, to make sure the dealer has done all the newest flashes.

Any opinion on that?

The 6.0 will defuel when EOT's reach 253*. Hopefully your EGR is deleted and you have synthetic oil if you're planning on driving the truck like this for a few weeks.

It looks like your "delta" max was a 22 degree split. You seem to have been in a heavy towing situation. I am not sure THAT is really all that bad. Your coolant temp is getting up there, was the clutch fan engaging? I guess before I would dig a hole in the top of my engine to change the cooler, I woud look into the health of the cooling system. The oil cooler should not be failed/clogged after 30000 miles and a coolant flush replacement. Do you still have an EGR cooler?

I agree. Sadly, it happens all the time. Sometimes in less than 10k miles.
