Mixing Glycol and Water

If possible, it is recommended to purchase the antifreeze solution already pre-mixed by the
manufacturer. If this is not the case, always pre-mix the glycol and water prior to adding to the system.
The chemical reaction between the two will release oxygen. Oxygen is extremely undesirable in a
closed loop system.
