The bottle says it's only good down to -34F. What do Toyota dealers in the Dakotas, Minnesota, Vermont and not to mention Canada use when changing coolant other than the factory 50/50 pink stuff? Does Toyota sell an extreme low temperature version like Honda does? My concern isn't the low temperature but that during a flush, there is still a gallon of water in the block, so using 50/50 coolant would mean the protection might only be down to 0F.
What do late model Toyota's use for coolant in northern states when the pink 50/50 isn't enough low temp protection?

Companies other than Toyota make a compatible POAT concentrate-OEM is one of them, there may be others. Concentrations of up to 70% coolant & 30% distilled/deionized will work, with a little less cooling performance in hot weather.
Guarantee the dealers here in Canada just use the premix 50/50 without issue.
Which is why you should never flush the block and only do a drain and fill. Radiator, different story since it can be completely drained.
Or, get yourself one of these:
Remember, coolant is effective up to 60/40 % concentration (AF/H2O) beyond that it can become acidic and cause some damage. This advice is for Dexcool but others are very similar now.
Toyota Red Concentrate Coolant ( 00272-1LLAC-01 ). Dilute accordingly, up to 70/30, for increased Freeze protection.
I want the long life pink but Toyota only sell it 50/50.
That won't drop the freezing point if it's 50/50 antifreeze.
Correct. But if you want increased freeze protection, you should use the Red concentrate. Dilute accordingly. Completely compatible, but shorter (5 year) service interval.
Toyotas have easily accessable drains on the block. Ours has one on each side plus the radiator.
He's saying mix it with a higher percentage of AF. You should see something like this on the back of the jug.
Yes I understand raising the concentration to lower the freezing point but around here the dealers only have 50/50. I can't believe they also use that in the northern states where it might get below -40F or in Canada or Alaska where it might drop below -50F. I'll have to find a brand of pink that is full strength. I won't use red when pink is the newer longer lasting type.
I no longer have a Toyota, but I only used 50/50 mix of Toyota red on my Sienna. I'm not as far north as other provinces, so we really don't worry about engine damage.
Maybe they use 60/40 or 70/30 ratio further north. Many people in colder regions use block heaters in the winter and you see plugs outside for people to use in parking lots etc.
I don't hear of people with many issues of damage using incorrect coolant ratios. At the local auto parts stores they have concentrate or 50/50 mix. I'm sure some people use 50/50 premixed further north and don't think twice about it.

Google says it went down to -61F someplace in BC last year. Wonder how many cracked blocks happened.
Honda sells this "Extreme Cold Weather Concentrate" for just such a purpose, but are you in danger of exceeding the low temperature limit for the Toyota 50/50? If so then perhaps that's why the old Toyota Red full-strength is still being sold along with the pink.
