I believe that John Deere "Liquid Coolant Conditioner", TY16004, does the
same thing "water wetter" does - put it in water and it provides all the
lubrication and anti-corrosion qualities needed.  Is safe to run without
commercial antifreeze (ethelyne glycol (SP?)  with additives).  Both water
wetter and the Deere conditioner supply the "additives", without the glycol.

Deere's conditioner is cheaper, and in my area, easier to find, than water
wetter.

Water cools better than 50/50 antifreeze/water.  That is what I'm going to
use in summer when not anticipating flying above the freezing level and will
be in HOT weather on the surface and initial climb.

In Fall, I can economically change to std 50/50 antifreeze mix.

My confidence in the Deere product is based on a very nice 30 minute or so
phone conversation with a Deere coolant "engineer"/expert.  He answered all
my questions and, while having to say "Our product is not for airplanes", I
am sure the Deere product will meet our needs for wear and corrosion
protection - it is a quality product.
