Coolant pH

Testing a coolant’s pH level will indicate its acidity or basicity. pH is a measured on a standard scale from 1 to 14. Values above 7 are considered alkaline and values below 7 are acidic. Inhibitor additives are added to coolant  formulations typically maintaining pH between 7.5 and 10. This prevents corrosion of the cooling system components.
