I plan to run "no antifreeze" in summer - just water with John Deere coolant
additive for equivalent protection and lubrication of water pump that
additives in antifreeze give.  "Water Wetter" used by motorcycle racers does
the same thing but is far more expensive and less available.

When the freezing level comes down in the winter, I'll drain that stuff and
put in 50-50 water and standard antifreeze.

The reason for using only water in summer is to get best possible heat
transfer (water is better than 50-50 mix).  When it cools off, use
antifreeze and nothing will freeze in the radiator (down to ? degrees F,
what ever that is).
