Antifreeze solutions contain cooling system "maintenance" molecules, perhaps a variety of corrosive inhibitors, chelators, PH buffer, detergent, etc... which will NOT help keeping things cooler but probably a good idea to have.
While
distilled water by itself is truly ideal. It is very unlikely that you are pouring
distilled water into a "pure" container. The existing cooling systems likely contain all manner of foreign materials, ranging from oil to organic compounds. Regardless of how well we think flushed the system.
So the addition of a 'stabilizer' is somewhat of a requirement, that changes depending on the application.
For example if racing around a track, the stabilizer would probably be limited to de-foaming agent and PH buffer, because you want the max amount of water in the cooling system for performance reasons. Water is the best coolant (for our vehicles, because it is safe); limit the use of everything else.
