The cooling system of automotive and other engines are permanently sealed by a cooling system sealant which will seal both small leaks caused by corrosion and large leaks caused by warped heads and blown head gaskets. The cooling system sealant comprises a major part of sodium silicate and minor parts of blue vitroil and gum of arabic. The cooling system sealant is added to the engine while running and with the coolant warmed.
