Now someone will chime in with "rust inhibitors? with an aluminum block and plastic radiator tanks?"
Where did you read anyone recommending to run straight water?
And last time I checked, our cylinder sleeves are not aluminum.
Are you aware what anti-freeze even mostly consists of?

Finally someone that sounds like they aren't pulling facts out of their ass.

You really need to stop stop posting your invalid theories.
The only thing that helps the radiator remove heat is the air that goes through it (naturally and with the aid of the radiator fan).
Water wetter is normally used as an additive for individuals running a mostly straight water mix. It helps to prevent rust.
Although it is not uncommon for it to be added to a normal coolant mix.
