you may need a small amount of anti freeze in the I/C system, water wetter does not really protect from freezing. I would suggest a coolant like the one in Toyota's, one becasue it is not DexCool, and two it is red so it will look cool.

 

I'll do a 1/3 mixture with the 3 and should be good to go then. Right?

 

no, water wetter doesn't work like that, what you can do is buy a premixed 50/50 solution and add water wetter to it. In other words, water wetter is like an additive and you don't exactly run it like coolant, when you pick it up, look on the bottle and you will understand or go to Redline's website.
