every 5 years or 100,000 miles you can flush the cooling system ,

drain the system firset , fill with water , add the flush and let the car run until it reaches normal operating temp ( 180-210) , let the car cool down and then drain the water and the flush liquid out , fill up the radiator with the new coolant , a 50/50 mix , make sure you let all the air out , there should be air breathing points that you can let loose till all air is out
