Your automobile MUST be running and you pour the sodium silicate into the radiator, allow it to circulate and flow through the areas needed. The high temperature's will cause it to harden (like glass). "This technique works because at 210-220 °F the sodium silicate loses water molecules to form a very powerful sealant that will not re-melt below 1500 °F." A sodium silicate repair of a leaking head gasket can hold for up to two years and even longer in some cases. The effect will be almost instant, and steam from the radiator water will stop coming out the exhaust within minutes of application. This repair only works with water to cylinder or water to Air applications and where the sodium silicate reaches the "conversion" temperature of 210-220 °F. I would highly suggest disconnecting your heater just to be on the safe side. To prevent it blocking the heater core.
