Can you go by coolant temperature to know when it's OK to "shut down"? Also, in warm or moderate weather, is it better to idle a minute or a few before driving off?Like what Capt stated, not much reason to idle more than about 10 minutes. Diesels don't heat up quickly by idling (they actually cool off), when the truck is cold you let idle for a few then drive it easy until it gets up/over about 150°F. If your really working the truck pulling a trailer it a good idea to let it idle to cool off for about 5 minutes before shut down.
You can sort of go by coolant temp for shut down temp but the cool down is for the turbo. The ideal temp is to watch the Pre-Turbo temp(EGT1B1). Cool down is a good idea for any turbo charged vehicle.Can you go by coolant temperature to know when it's OK to "shut down"?

Edit: I have a 2019 Classic, 2nd Gen. Perhaps that doesn't matter with the cooling down part of the question.
Not sure we know that as the OP has not yet returned to clarify what generation Ecodiesel he is talking about. Often people just get on the forum and go with the first thing they see, which is 3rd. Generation here.Since this post was in ref to 3rd gen, does anyone know if the owner's manual for 3rd gen has the same warning against extended idling that's found in the 2nd gen manuals?
Several temps to consider. Oil temp, coolant temp, Egt for example.Can you go by coolant temperature to know when it's OK to "shut down"? Also, in warm or moderate weather, is it better to idle a minute or a few before driving off?
