So it's -40*c here which is equal to -40*f right now. I figured my truck wouldn't start (no block heater on the new motor) and I was right. The P/O said he had reused the old plugs and wires from the last motor so I decided to try changing that out and giving it a try which would still be a long shot. NEVER change plugs and wires in this kind of cold unless you're a Canadian. I parked my '99 behind it and sat inside thawing the tools and plugs so I could handle them between each change and got it done in record time because it was so cold. Well, first try it stumbled a few times but fired right up. Took a little encouragement to keep it going but the '07/'08 fords at work never start when not plugged in. These motors are awesome.

I've had mine start in -40F/C ! That was fuuun ..... (that was sarcasm if someone didnt catch it)

Props to you for touching the metal at -40*! lol. Glad it worked, too!

The only one I had trouble with was the very back one. The others I didn't have to touch any metal but when I tried the back one I pressed the back of my thumb on the valve cover for maybe 5 seconds and got bad frostbite in a small spot. I ended up putting a piece of cardboard between my thumb and the cover to give myself time to get the plug started in the threads.

It was -57 with the windchill in the north where I work and we spend a lot of time outside so I'm used to it. The thing I hate is working with cold fingers.

With my 0w-30 amsoil my 20r starts so much easier even unpluged. Was only -35C last night and it started right up unplugged while my friends new jeep wouldnt even turn over. I would plug it in but was retarded and didnt install the block heater when i rebuilt it.

I cant stand cold weather. If it's below 70, it's too dam cold for me.

I need to put some thin oil in it, the new starter and battery can't turn it over very fast when it's that cold out and there's no block heater on my rebuilt motor either. I'm going out to get 2 of the stick on oil pan heaters today. One for the oilpan and one for the tranny which is hard to move around when it's really cold.

The magnetic oil pan heater might not stick to the manual trans (aluminum housing). I bought a 1000w inline heater for mine when I lived in Manitoba(made for tractors). Plug in, then start truck and instant hot air. Working on it in winter was nice too, could warm my hands on the block.

AP4CHE

They're not magnetic they're flat pads you use 3m adhesive to stick on, they'll never come off. Then you just run the cord up to the front. I put a block heater in now but I'm going to buy a stick on for the trans soon.

my truck had to crank a few long times the other day and it was only -11. do you guys pump the gas first or hold it to the floor or what? when its warm I hold it halfway down and it pops right off, but maybe in really cold thats not working?

AP4CHE

I pump it a few times then when it's cranking i barely press on it, if I give it too much gas it won't start. Then once it's started you have tp work the gas for about 30 seconds to keep it running. But that's only when it's really cold.

Just the same they probably couldn't handle the south's heat and humidity. Seriously though, that's ridiculous.

Whats the temperature there now man? We're getting -55*f (around -48*C) ( little to no wind chill, maybe -60 with the little wind thats blowing) and some places around town have reported -65*F (-54*C). My truck takes a bit of loving to get started. Loving= 20 minutes of sitting in the -55* weather . Do you have any trouble with the ignition cylinder sticking when its this cold? I have to heat my key with a lighter before it will turn.

I think it was only -40 today but my friends 96 tacoma took a lot of time to start, wasn't plugged in.
