Du Pont Cooling System Cleanser Before a Drop of Anti-Freeze

Popular Mechanics


DuPont use to make a great radiator flush, but I have been unable to find it in a number of years. I have used Prestone radiator flush several times with very good results. Follow the directions and do not rush it. The instructions even tell you to drive the vehicle for a few days with it in the system.
