Antifreeze rated temperature for 4520r?

[North to Alaska]

I did a bunch of looking and I can稚 seem to any info on How cold the coolant is rated for?

Yes, I need to get a tester but until than, anyone have a knowledge on this?

Yes, the OEM antifreeze that came in my M6040 tested out to -32F.

What I thought but just wanted to check
Winter in Alaska and all
