Radiator Stop Leak features a patented formula that quickly stops leaks in radiators while also protecting against pitting and corrosion. Radiator Stop Leak takes sealing performance to a higher level by both stopping the leak as well as the corrosive condition that causes leaks in the first place. Radiator Stop Leak particles have been chosen to seal even large leaks without interfering with the flow through the radiator and heater core tubes. It also boosts corrosion inhibitors to protect against pitting and corrosion, which cause radiator leaks.
