I guess I could explain my temps.
On a 35° morning(really the coldest it gets here), all fluids are around ambient. I'll let it idle 5 minutes or so before taking off, fluids at 60° or so, trans a ways behind. I'll drive my 2-8 miles to where I'm going thru the week, EOT no hotter than 140° and ECT no greater than 160° if that. Shut down, cold soak for about 8-10 hours, repeat.
Now on the weekends, I do tend to run the highways for extended stretches and everything warms up then. When it's in the 30's, the 1st thermostat cycles in and out on the primary cooling loop, maintaining 176°-183° on the water. EOT usually 5-8 degrees higher. Trans just warms up until it hits the 190's and hovers around there like it is supposed to when unloaded, although in the cold it will take 20 or so miles to get there on the HWY from an ambient start. By HWY I mean 75-80 mph.
It's not great to short trip a modern diesel with emissions on it like I do, but I have for 200k and I don't have any problems. I even get lazy sometimes and don't let the DPF burn all the way out. I was obsessed with "perfectionist driving" with a modern emissions diesel when I first got the truck; now I just drive it like I would any other truck....and quite honestly, I expect that out of a vehicle at this point, emissions or not. Burn it out on the highway once or twice a month, if the cards fall in favor. These motors are pretty resilient...I'm not too worried about it anymore. Just drive it and enjoy it.
Yes, I do hate doing 300+ miles on the hwy and it wants to start a regen <3 miles from my destination, most likely once I come off the highway and into town...I wish there was a way to command an active regeneration cycle while in motion, because I promise you I know better than the computer does 99% of the time, lol.
Too many toys for it to list
