Park so that the engine faces the dawn.
Put cardboard in front of the radiator.
If you're going to be somewhere for less than twenty minutes just leave it running.
Always let it warm up before taking off.
Keep the gas tank full. Look for fuel line anti freeze.
Keep a can of wd40 handy to spray on the door locks in case they freeze up.

Bring good sunglasses. When the sun is up that far north it is blinding.
