That's the wrong type of alcohol to use. You'll be better off with ethyl alcohol. Now what is this exactly? It's a corn alcohol basically known as Ethanol. Or down at the Beer-n-Wine store as 200 PROOF Vodka.

Use about 10% Propylene Glycol, 10% Ethyl Alcohol, and 80% Distilled Water. Sorry, you'll still need a very small amount of the green stuff to prevent corrosion in the system; if dis-similar metals are used in the cooling loop.

If your reservoir is made of HDPE, it will be safe. Likewise, if your using something like (Superthane) Ether Polyurethane tubing.

Peace!
