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.
