will pure antifreeze if used for winterizing a boat engine freeze and expand and cause damage????

Your argument that an alternative anti-freeze may alter the operating temperature of the engine is flawed. No matter what chemical is used as a coolant, the Thermostat will determine the temperature at which the engine operates. A more efficient coolant will not alter the function of the Thermostat. After all, when the Thermostat is closed, the coolant is not circulating, and therefore, not cooling anything. No matter the freezing point of the coolant, the Thermostat controls the engine temperature.

Suggesting that an alternative anti-freeze will result in various chenical changes and chemical breakdowns, is also a flawed argument. The manufacturer of such products, surely would have taken such complications into consideration. It is very doubtful that a manufacturing company would invite a liability such as you have suggested.

Even though containing the coolant in a pressurized system does raise the boiling point of the coolant, the engine temperature is still controlled by the Thermostat. As long as the cooling system is capable of removing sufficient heat (and that is part of the reason for using pressure to raise the boiling point), the Thermostat will maintain control of engine temperature, in a properly functioning cooling system.

I loves that p-chem. I was making an industrial amount of pink lemonade one time, from those frozen concentrates that come in cans at the supermarket. I needed a funnel and not having one handy I cut the bottom off a soda bottle and it did quite nicely. Well I had washed the soda bottle and it was still wet as I was using it. The pink lemonade mixture was mostly liquid even though I had pulled it out of the freezer and the water droplets on the outside of the funnel froze instantly as I ran the cold syrup through it.

I just use water and hope for the best.

I may have to do this for our New Years party

..that is, the ethanol ice cubes.

Interesting point about maintaining a homeostatic temperature range.

On a side note, I’ll mention that my other half’s car runs noticably smoother using mid-grade gasoline (c. 89 octane). My beast, however, doesn’t really care one way or another.

No, with liquid nitrogen you make ice cubes of pure anyhdrous non-denatured ethanol. They sink to the bottom of your drink, keeping it cool. And when they do melt, it does not dilute the drink, it spikes it!

ethylene glycol ice cubes….what a waste of liquid nitrogen!

When I was looking up cool things to do with liquid nitrogen (it was for a middle school demonstration), one of the suggestions was to make ethylene glycol ‘ice cubes.’ or anti-anti-freeze
