Idling Overnight at -35F - Long Term Damage?

You guys are WAY over thinking this. I ran a toyota 5.7 up in alaska for years in those temps. Granted, I ran the toyota 400w block heater (not quite strong enough in those temps) along with an oil pan heater and pad heater for the battery. Your visit sounds temporary and as such, i wouldn't worry a minute about it. Just give it time to warm up properly and don't drive crazy trying to warm things up. Start it up and let it idle for 10 minutes or so, turn on the seat heaters, and drive normally. At those temps, the engine WILL make some noise on startup. Its normal for those extreme temps. Your cruiser will be just fine.

Most importantly, make sure your battery is in good working order. At those temps, you're not going to get a lot of power out of it to turn that big cold engine.

battery is 18 months old and I hAve a new lithium 1000A NOCO jump pack
 
A block heater is your friend as well
 
I'd take the jump pack inside, not leave it in the truck.
 
What temp does our factory coolant start to freeze at?

Pre-mixed 50/50 SLL freezing temp is -34F
I think dealers in Canada use a 70/30 mix that's -90F.

Sounds fun!

My only experience was in this same week in the mid 80’s, it reached -25. We had 3 trucks parked outside, none would start.
We contacted a family friend who worked in Greenland for several years. He told us to remove a spark plug or 2, turn the the truck over a few times to warm up the oil, reinstall spark plugs and started up fairly easy. Then he recommended a good block heater for next time! Seems like a good idea!
 
Thankfully our block heater for the 5.7 is a 15 minute install job. Granted, its a little undersized but every little bit helps at those temps.

You must have used a different one than I have. Took a lot longer than 15 minutes! Worst part is routing the wire, which is too short. This is the one I have:

That looks different than I remember. I used the OEM one but agree with the cord being on the short side. I had zip tied it to a vane in the lower grille and I would tuck it away during the summer months.
 
Should not a problem at all. One of my 200 series in Mongolia and winters are brutal -35s to -50s.. ... IT ALL works fine. Just takes time in AM to get things warmed up

That's a plug I have never scene? But looks like a simple install. The ones I have used you have to remove a freeze plug from the block and they directly heat the coolant. It radiates the heat where the coolant travels. I have a heavy duty timer and extension cord. 4 hours @ -25 the motor and guts are about 40. The rare occasion it gets below -30 I just leave it plugged in.

The actual heater isn't too bad to install, you just slime it up with this special thermal heat transfer grease, slide it into a hole in the back of the block near the bell housing. No freeze plugs to yank out. But it is very close to the exhaust, so I was really careful about running the wire, and then it wouldn't reach the front of the truck all the way. Fortunately I was installing one of those nifty NOCO socket things, so it gave me about 18" of wire to extend. Came out nice and convenient.

I left my cruiser at the airport last year - open parking with the grill facing into the wind like a big dummy - and we had -35F overnight for 2 nights.

Started just fine, took it easy until I got to the freeway.

Make sure you have the factory fill 0W20 or whatever they suggest and a good battery and you will be fine. I have heard of guys using an incandescent trouble light to keep their battery warm. Cheap insurance if you have an outlet, just wrap a wool blanket or similar in the area to maximize the loss of heat. Could also lay a thick wool blanket over the engine when you park, that will help. Make sure its a wool blanket and not synthetic.

Do guys ever block the radiators or grill openings in super cold weather?

Materials do not experience wind chill.
 
They absolutely do. Cools metal and fluid faster than calm air just like flesh. It’s why we have fans on our radiator. What it doesn’t do is lower the temp below ambient. If it’s -35 it’s -35 regardless of the wind.

If you want the truck to warm up, tail into the wind. Same reason you run up an aircraft with the nose into the wind.

Agree that air movement increases cooling. What I meant to say was that if it’s -40F with a -95F windchill, the metal doesn’t get any colder than -40F

I used the OEM one. From what I remember (~6 years ago) it was a very easy <30 min job start to finish. I had it on a frame lift, would have been slightly longer laying on my back.
