Your cooling system should be flushed and ‘pH balanced’ at least every 30,000 miles or two years (whichever comes first). Flushing your cooling system, and most importantly, pH balancing your anti-freeze, will help reduce the acid level in your cooling system that promotes electrochemical reaction. This reaction causes degradation of the cooling system components. Flushing and pH balancing the coolant will save you money by extending the life of your radiator, heater core, water pump, head gaskets, radiator hoses, heater hoses, and freeze plugs.
