Cleans that radiator easily
I have a number of vintage vehicles that I flush their systems every few years. Picking up a case of these will give me all that I need to do all of them with just one order. Easy to use too, drain system and remove thermostat, refill with water, poor this fluid cleaner in and run enging for about half an hour. Drain and flush back and forth with hose. Once it all runs clear, reinstall thermostat, refill with coolant and run topping off as needed.<br />As a professional auto tech I have used products like this many, many times over the years. This one seems to work as well as any other that I have used.<br />Included are 6 bottles of cooling system cleaner. Nothing more is needed to do the job at hand.
