In the Yukon, it's critical you let your car warm up. A block heater, battery blanket and oil pan heater are all needed, but they're only heating the actual engine block.
Think about how cold the oil in the transmission and diffs are.. let alone everything else.
You also want to drive extremely smoothly and slowly for the first ~5 mins to let everything circulate and slowly warm up to running temp - sudden moves or turns tears apart CV joints, and destroys other rubber seals.
Have you seen what engine oil looks like past -35C?
Butter. Same color, same consistency. You can cut and spread it with a knife. Those geegaws aren't helping there.
Also, there is a hell of a lot more in a vehicle that's sensitive to extreme cold than an engine.
I said less for a reason. Most people don't have to worry about -35C. Cars start reliably down to fairly low temperatures, so they don't need to worry about it.
We're replying in a thread about someone trying to use a vehicle at -40C...
>Cars start reliably down to fairly low temperatures
Start? As the parent comment states, that's the least of your problems.
Stay warm!!
When I got back to beijing, it was only -10, I felt like I could wear shorts.
One time, I drew the short straw and had to go pick up our SUVs at the parking lot upon landing. They were outside, plugged in.
The car started with the saddest sound I ever heard a mechanical thing make.
I put it in reverse, hit the gas, and pulled out of the spot. Then I put it in drive and hit the gas- and the car moved backwards. Every gear except for Park and Neutral did the same thing: reverse.
I reversed around the airport parking lot to the terminal and walked into the Hertz. When I explained the problem, they had clearly heard it before. "Don't worry about it. Just leave it on for a few minutes and you'll be fine. Transmission fluid's frozen."
