Even at -10, I take off as soon as having started the engine.

Forgot to mention that letting the turbo cool (EGTs go down) is also important, even when it's cold out.

Yup. It's quick and easy.

When I was a young mechanic at a big truck shop in Vermont, some of the loggers had connections on the front of their pickups or log trucks, that they hooked the hoses to there skidder out in the woods, then opened the valves, they basically were doing a "flush" by circulating there hot coolant from the truck, into the skidder ... Finish there coffee, and start the skidder, do the opposite when they were ready to go home ...

What was the reason for hooking up at the end of the day? If I read your post correctly that they did the opposite at the end of the day. I would Just be sure the same vehicle always was hooked up to the same skidder. We never did this because we had welder generators and portable heaters so if necessary we could plug them in and run heat on an engine both.
