Well, I'm from up North, not quite where your going though. I only average somewhere between -30 and -40. I think my own personal record is seeing -45 in the mirror one morning.
There are several things that I can think of off the top of my head.
Install at least one block heater, if not two.
Install a
magnetic heater on your oil pan.
Install a
battery blanket.
Purchase a propane tiger torch to melt your oil pan, in case you forget to plug all that in at night.
Install
plug caps! Keeps the crud out of the prongs, and keeps the prongs around longer than a year.
Migrate away from 10W30 to at least 5w30, if not even 0w30. I like Castrol?
Change over your orange dexcool to regular green stuff. The orange stuff over time gums/freezes up the smaller passages in the engine block. You should see the pics from my old engine block.
Buy one hell of a saftey kit, including a wollen blanket and food.
Make sure that you get your truck undercoated. I personally use
Krown on mine. After seeing my dad's old beater truck after 14years and very little rust, I'm convinced. He bought that old truck new and had it Krowned every year.
Oh, and install studs on your winter tires. This year, I'm going for
Winterforce studded tires.
That's all that I can think of.
BTW, your crazy going that far North!
Welcome!
