Don't put your engine at risk from the corrosive effects of coolants mixed with non-distilled water. The minerals in regular water and well water cause corrosion and degrade the performance of the coolant. CSP neutralizes these minerals and prevents damage due to hard water.

This is especially important when you add make-up water to the coolant system. CSP prevents corrosion in modern "orange" OAT coolants, traditional green anti-freeze and straight water. Keeps engine coolant passages clean and lubricates water pumps.

Do not mix with other coolant additives.
