Abstract
A crack in a cooling system may be sealed by the direct addition of dry or powder sodium silicate or a glycol based slurry of sodium silicate. The sodium silicate may be used in conjunction with an inert bulking agent, such as a cellulosic material. The sealant composition may further contain a metal which is non-reactive with sodium silicate. The method has particular applicability in the treatment of cracks in the cooling systems of internal combustion engines.
