AntiFreeze Question
 

When mixing a gallon of anti-freeze with water do I have to use distilled water or will regular tap water work? I know you can't use well water because of the crap in it.

They say distilled water, because tap water has chlorine, floride, and trace amounts of a bunch of other stuff. Buy distilled water - even bottle water like Poland Spring has sodium in it.

Best to use distilled as it has 99.9% of minerals removed from it. It's the minerals such as calcium that will eventually clog your rad.
