Good advice for everyone, check the anti freeze each Fall to get ready for severe winter. Here in central NC the night time temps will stay in the teens until Sunday night.

In central NC tonight, 14*, Friday night 11*, Saturday night 10*. My anti freeze device says I am good down to a little under 10 so I will cover the hood and fenders with Harbor Freight moving blankets and add a 350 watt heating lamp under the oil pan. $25 spent may care for the old F enough that I will be able to enjoy it in the spring and not be looking for a rebuild. Once the coldest weather passed I will drain the radiator and add fresh anti freeze and get additional protection. If I ever do a rebuild I will look into the non-water coolant that I have seen advertised on some of the TV car shows. Anyone know anything about this stuff?
50/50 mix is all i run up here even in -30c and never had an issue.
Just add straight antifreeze to top it off and run the engine for 15 mins then add some more straight. You will be fine.

Its not just antifreeze its also coolant lol. Keeps water from boiling in the summer. You can run same mixture year round good to +40c or -40c lol. You down south guys make me chuckle sometime haha. All good im envious of your temps

Checked mine last weekend, my tester goes to -40 F, and all 5 balls were floating away.
I might just add some distilled water to that mix.

I'm way late to this conversation but at 15° F you will never crack a block overnight. That's barely below freezing. All that likely happened is the metal parts shrunk and your hose clamps weren't tight enough allowing a leak. Coming from a warmer climate they worked fine but swing the temps and that often happens. 15° F won't freeze a water bottle left in my console overnight.
Another canadian chimed in thanks! haha

There as an advantage to living down south. We roast in the summer, can't handle the lower temps in the winter and when there is a threat of snow the grocery stores sell out of bread and milk and most people have no idea of how to drive in snow. Watching them drive in the snow makes for good comedy. But I wouldn't live anywhere else.

How 'bout you Canadian's keeping the arctic clipper up there in the arctic where it belongs?! We're looking at -5 tonight and -10 tomorrow night and that's F not C. 50-50 mix has always kept my engine (not myself!) thawed in even lower temps.
Stay warm!

-10°F is getting cold. We had what felt like a week of -28°C (that's -18°F) last week. Edmonton, a further 300km North of Calgary had windchill numbers pushing -40°C..... which is -40°F. This week has been just above freezing (32°F ?).
I have never used anything other than 50/50 mix and never had freeze up issues or boil over issues.

Yah it was a shock to my system last week when i came from sunny palm springs to Sask and went from 26c to a balmy -36c at the airport lol.

Glad your motor is fine OP!
50/50 anti-freeze distilled water mix... how much (quantity) antifreeze equals 50% in a normal FJ40 2F system? About to fill my new motor with antifreeze/coolant and how would I know when to stop filling?

Probably have it figured out by now but will give this bit of advice.. It you have frozen water in the engine loosen the fan belt before you start the engine so you will not be turning a frozen water pump. Hope this turns out to be a minor annoyance with nothing serious resulting.
some of us old timers at work were messing with the new kids and kept calling it anti-boil. they had no clue what we were talking about.
LOL^^^^^^
Blanket over engine, tarp over hood. Small space heater on the ground under the engine.
I had the same problem moving from South Florida to Philadelphia. I had to much water mix in mine from the warmer climate.

Hopefully my job stops getting in the way of spending time on working on my 43 later today and I will be able to start figuring out what is broken. Based on feedback from this thread and others that I have read this is what I am planning to do. Keep in mind, I am a novice at vehicle repair other than the basics. Got to start somewhere right? I've ordered the 2F engine repair manual from Toyota and the Haynes repair manual. Also, forgot to mention before this rig doesn't currently have Heater/AC......my plan was to eventually have a vintage air unit installed (not by me)
1. Pressure test the cooling system
2. drain/flush the system
3. If it is just radiator and/or hoses then try to replace myself.
4. If freeze plugs are leaking then tow it to mechanic
I want to make sure I replace anything mechanical in the system while I have it drained if needed (water pump & thermostat). Is it possible to test those with the system drained or should I just plan on replacing?
