Prestone antifreeze tester says the liquid is rated to -15 degrees. Is this when it actually freezes solid, or gets slushy?

I would put a little in a Dixie and see how it does at 0F which is what your freezer should be.

Considering the precision of those testers, err on the safe side and figure it will eventually freeze at -15, with the normal transition from liquid to slush to soft ice to hard frozen.

If you have the chance and location, maybe a radiator drain and refill with 100% coolant is in order. (Adjusted for system capacity)

Yes! 50-50 is good to -34F (I think that's about -37C)

perhaps the guy meant he should drain a bit of the coolant in the system. maybe a litre, and then refill with concentrated coolant. To adjust the freezing point. i think that what what he meant.

100% will freeze.Water is the carrier of thermal conductivity.

Slush and solid is just a matter of time. The differentiation is thermal mass (how much heat the engine block retains.

You could make a practical assessment of how often and for how long is the temperature actually -15? Maybe not long or never.

Still, to me that means your as is a little light, as it still gets quite cold in IL. I'd just siphon a small amount of your current AF and replace it with neat AF and call it a day. You can do a calculation to determine how much you need, and you definitely don't want to get too much glycol in there, but you should add some.

Severe cold is hitting tonight. I plan on warming up the 54, then dilute some more antifreeze.

A month ago I figured -15 would be fine! Ugh....

My Prestone antifreeze tester pictured below turned out to be incorrect.

Try to find a shop that has a refractometer to test your juice. It takes less than 5 minutes time.

I just got back from the yard. The beater 54 took 5 cranks to start, I let it run for 30 minutes, added about a gallon of 60/40 and let it run another 10 minutes. My biggest gripe would be a cat or critter making a home on the warm engine!

Running a 5w-30 National brand oil, and a blue bottle of STP...sounded great upon start up! Not bad for a 230 flathead from 1954 in bad temps!

Precisely. I wish people would read for content.

I said, "radiator drain and refill...adjusted for capacity". We don't need to do the math for OP but an adjustment from the current protection to a 50/50 situation would be a good idea.

And to be fair I should have said to adjust to 50/50 in the first post.

A decent coolant refractometer can be bought for around $25.

Those floating ball things are worse than useless.

100% ethylene glycol would result in protection to about 10 F.

That's the freezing point of pure ethylene glycol, but when you mix ethylene glyclol with water, the mixture does not readily crystallize and the freezing point of the mixture is depressed. So a mixture with water is better than pure antifreeze.

The other problem pure ethylene glycol presents is that it does not transfer heat as well as water. For a cooling system with pure ethylene glycol the circulated volume must be increased compared to a system with clean water alone.

Ethylene Glycol Heat-Transfer Fluid

The optimum mix for antifreeze purposes is about 2/3 ethylene glycol to 1/3 water.
