Yep. Just need to warm up the engine. By starting a fire underneath it.
sump heaters, glow plugs, ether....sure. Eventually.
Some days you really don't want to get out of bed.
As long as it has winter diesel in the tank, it'll start. If it's the summer mix, the fuel will have gelled and they'll have to wait for the spring thaw.
I think the more important question is will the guys beard break off.
maybe....oil freezes at -42F
Will have to fire up the big salamander. And maybe place some canvas all around to keep the heat in. Then once it starts, don't shut it down until spring. https://www.constructioncomplete.com/insero-1-000-000-btu-diesel-indirect-fired-heater-ht1010.html
it will never start. it's just a snow sculpture. like a snowman.
