it's ethylene glycol can be green or red or clear...but 50/50 mix with water is the designed formulae~ DO NOT use plain water...this is a recipe for disaster....drain intermediately and fill with the correct 50/50 mix.. okay...thanks for asking~

Ethylene Glycol could never mix with Ethylene Glycol...they are the same~ water and you'll have Flint, Michigan all over again~
