If anyone is curious if a Gladiator starts in -40...

[Rocksalt]

Mine cranked right up in -27 2 weeks ago. But anything beyond -10 prrolly a good idea to have a block heater

not true. I had a bottle of 90 proof whisky in a bag on my roof rack. Drove 8 hours in 15 degree above zero weather. it slushed up due to effects of windchill. Without that it would need to be -30 for same effecr.

Sorry- wind chill is a human temperature PERCEPTION. It is based on the chilling effect, evaporative effects, etc.

A quote from wikipedia =
All the formulas attempt to qualitatively predict the effect of wind on the temperature humans perceive.

A bottle can NOT be cooled to below what the actual air temperature is because wind across an inanimate object cannot be colder than the air that is flowing.
So if it's -20 outside, the bottle, radiator, bumper, bolt, whatever, can never be below -20 degrees.
For humans - it's PERCEPTION - how cold does it FEEL. A bottle can't "feel cold". It can only be cooled as low as the actual air because air that is colder than the bottle, radiator or bolt is removing heat energy. Once an equilibrium has been reached, there can be no further energy transfer.

Ask a meteorologist.......... among my interests are the earth sciences, meteorology, physics, psychology, etc. I'm quoting these other sites because as often happens, seems I have to prove it -

Here is a quote from a meteorology site - word for word -

The only effect wind chill has on inanimate objects, such as car radiators and water pipes, is to more quickly cool the object to cool to the current air temperature. Object will NOT cool below the actual air temperature.

Why would anyone live there? LOL that's too damn cold!

That started miraculously well for those temps. This is Anchorage but I know the guys in Fairbanks have us both beat. For years I had an old M1009 with the military 24v starting system and a manual glow plug controller. In Fairbanks in January not plugged in it would fire up. Would take a few cycles of the plugs but it would run. The old 80s diesels would not really ever heat the cabin like a gas car could though. Too much heat going into combustion didn't leave much for cabin heat. That's why I ultimately sold it I just got too old to keep freezing my balls off for 4 months of the year and my kids didn't want it.

Drove a VW TDI for a few years. Thank god for heated seats as the inside wouldn't heat up for the first 5-10 miles. When My commute to work went from 40 miles to 5 my vehicle never actually warmed up and I'd freeze every day to work. Decided I had enough of that and let VW buy my vehicle back with the whole recall thing. Got a Jeep and now I'm warm all winter long!

I am in lloydminster mine cranked up at -51 C with the windchill.

It was -52 with windchill in Saskatoon... since it's a lower number, I don't think I one-upped you... maybe I one-downed you?

Windchill only affects things that produce heat... the wind blows the heat away from the core, making it feel colder. A high wind would've lowered the temp of your whiskey more quickly than if it was in no wind, but it would reach ambient temperature and go no lower.

Cuz we ain't weak.

... at least thats what I tell myself to make it through. lol

You guys just aren't used to the diesels I had to deal with in the 1980s - farm tractors, etc. If the ether was empty, you ain't gonna get it going. JD diesel tractors were the worst. Crank and crank, hit the ether, might start - then it sounded like heck and had no power under it ran a few minutes.

My grandfather was a Army diesel mechanic in WW2..... In Greenland. Safe to say they were busy.

Can't top that one! I bet they kept 'em busy for sure. No engine block heaters, either!

Well, not Florida, but mine did start in +40 degrees temp this morning. I barely survived....

bullshit explain how it slushed up 90 proof whiskey in plus teens temp...

not only have you had many careers you reply to nearly every goddam post... well you are wrong on windchill as I have evidence.

Windchill only affects things that produce heat... the wind blows the heat away from the core, making it feel colder. A high wind would've lowered the temp of your whiskey more quickly than if it was in no wind, but it would reach ambient temperature and go no lower.

explain how 90 proof whiskey slushes up at plus 15 degrees
