Well, that's a spectacularly bad idea. Anti-freeze makes a ****ty
coolant. It's there to keep the real coolant - water - from freezing.

Some aircraft run on neat antifreeze. In very cold climates neat
antifreeze is recommended. * The reason I top it up is that the
antifreeze evaporates leaving water behind if there's a leak or the
sytem overpressures.

Show us a single auto manufacturer that says that when coolant is
needed you should top it off with pure antifreeze. *I'd also like to

a credible reference to any auto manufacturer that says in very cold
climates straight antifreeze is recommended. * Somehow I doubt
that because as someone else already pointed out to you,
*the charts for mixing all show that straight antifreeze has a
higher freezing point than the correct mix with water.- Hide quoted text -

A friend of mine had a Muskovitch (Russian) car years ago They
recommended straight anti-freeze. In temperature below minus 30dC they
recommended draining the coolant & running without. Special quick
drains were provided you operated levers under the bonnet.
The battery had a quick release so you could take it in the house.
The fan belt could be removed to take in the house too. Specail
Winter oil was recommended. None of this applied in the UK of course
but it was interesting to read.
