A Coolant Flush Is an Important Part of Preventive Maintenance. You may be under the impression occasionally adding antifreeze and water to your radiator to replace evaporated fluid is all the maintenance your car's cooling system needs. ... This important service is called a coolant flush.
A cooling system works by sending a liquid coolant through passages in the engine block and heads. As the coolant flows through these passages, it picks up the heat from the engine.
Properly maintaining the coolant system will remove rust and scale deposits in the coolant system. It will lubricate the water pump, remove contaminants and protect against rust and foam.
Most manufacturers recommend that the coolant be changed every 3 years or 80.000 Kms. Your technicians at Pro Oil Change at 55 Main St. E. can review your manufacturers recommendation for your specific vehicle.
