i would believe that if the water seperated out when standing still (like oil and water...mixes ok when moving but seperates out when left standing). the water and the glycol stays mixed and doesn't freeze in parts...if that were true, then why use glycol at all? eventually it would accumulate in the evaporator and lock up the flow. but we know this does not happen.
