Subject: Ratio of Liquid to Make Mixture

I have a 1 gallon (128 oz.) container of anti-freeze/coolant. I need 
to fill my radiator with a 60/40 mixture of the anti-freeze and water 
(60 percent antifreeze, 40 percent water). How much water should I add 
to the gallon of anti-freeze to make a 60/40 solution?  

Thank you.

For every gallon of anti-freeze you require 2/3 of a gallon of water.  
Assuming the same density of water and anti-freeze, this would be 
85.33 oz of water per gallon of anti-freeze.
