Abstract: A method of repairing a coolant system associated with an engine for a vehicle, including disconnecting a gooseneck connected to the engine and removing from the engine its thermostat; disconnecting a bottom radiator hose connected to the engine and flushing the engine with water; reconnecting the bottom radiator hose and reconnecting the gooseneck; refilling the engine's radiator with an antifreeze solution; opening a drain valve on the radiator and allowing a predetermined amount of coolant to drain out of the engine corresponding to a volume of a treatment composition to be added, starting the engine when the engine is cold, and turning on the engine's heater; adding the composition to the radiator of the engine while the engine is cold and idling; running the engine until the composition causes leakage and/or vapor in the engine's exhaust stream is substantially stopped; and stopping the engine and allowing the engine to cool.

Abstract: A composition for sealing warped or cracked engine coolant systems is provided comprising an aqueous silicate mixture comprising 50-80% sodium silicate, based on the total amount of silicates in the mixture, and 50-20% potassium silicate, based on said total amount of silicates in the mixture; the total amount of silicates comprising about 40-50% of said mixture; a glycol in an amount of at least 10% by volume of the composition; and the balance being water. A method for sealing warped or cracked engine cooling systems is also provided.

Abstract: 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.
