<p>A method of repairing a coolant system associated with an engine for a vehicle, including disconnecting a gooseneck connected to said engine and removing from said engine its thermostat; disconnecting a bottom radiator hose connected to said engine and flushing said engine with water; reconnecting said bottom radiator hose and reconnecting said gooseneck; refilling said engine's radiator with an antifreeze solution; opening a drain valve on said radiator and allowing a predetermined amount of coolant to drain out of said engine corresponding to a volume of a treatment composition to be added, said treatment composition comprising an aqueous silicate mixture comprising 50-80 % sodium silicate, based on a total amount of silicates in said mixture, and 50-20 % potassium silicate, based on said total amount of silicates in said mixture, said 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; starting said engine when said engine is cold, and turning on said engine's heater; adding said composition to said radiator of said engine while said engine is cold and idling; running said engine until said composition causes leakage and/or vapor in said engine's exhaust stream is substantially stopped; and stopping said engine and allowing said engine to cool.</p> |
