What Kind of Maintenance Do Radiators Require?

If you're like any other driver out there, you probably don't think about your car's radiator when asked about maintenance. But similar to oil changes for your engine, you should have radiator or coolant flushes for your radiator regularly. 


Most auto technicians and automakers recommend exchanging the radiator fluid every 30,000 miles give or take.
