How Often Should Your Car get a Radiator Flush? How Often Should Your Car get a Radiator Flush?

Several driving conditions make a scheduled radiator flush necessary for your car. Find out more about how often to have your car's radiator flushed from the tips and suggestions below.

 

Hard Water in Your Radiator

If the water in your area has a high mineral concentration, it is "hard", and this means mineral deposits, called "scale" can build up in your radiator, and in pipes and valves. A radiator flush once or twice a year will greatly reduce these deposits.

 

Severe Winter Driving Conditions

If you live where roads are heavily salted and sanded in winter, contaminants can build up in your radiator. Get the radiator flushed every spring, and replace all the coolant with fresh clean fluid for the hot-weather driving conditions to come.

 

Regular Coolant Changes

On average, radiator coolant should be changed every 2 years or after 30,000 miles (50,000 km). Use the mileage as your guide: if you drive 60,000 miles a year, change your coolant every 6 months. Flush the radiator and the entire cooling system with every coolant change.

 

Oil Changes

Change your car's coolant and flush the radiator every third oil change, or more often if you drive many thousands of miles per year.

See your mechanic if radiator flushes are not solving your engine problems.
