Cool-Gard II concentrate requires the addition of quality water to attain the desired concentration and freeze protection level. It is highly recommended that low-mineral or distilled water be used to dilute the coolant. Using impure water can reduce the performance and life of the coolant. See mixing ratios charts below.

The addition of coolant conditioner or supplemental coolant additive is not required. This is a fully formulated product.
