I strongly disagree with the advice you present for desert Listees. It is
incorrect advice, and should not be followed.
If a listee used straight water, even with wetting agents in a hot climate,
they would cerainly have boil overs because the coolant will definitely boil
in the heads, when they slow down or stop. Perhaps boil when driving -
causing a loss of coolant or worse.
Anti-freeze not only lowers the freezing point, it also very significantly
raises the boiling point of water.
