• Safely seals gasket leaks

• Pour directly into radiator
• No draining required

It is the easiest solution to stop head gasket coolant leaks. No draining of the cooling system is required. This formulation contains a combination of antifreeze compatible sodium silicate sealing liquid and various size gasket sealing particles which penetrate gaps and cracks and harden to permanently stop leaks. This seals because of the extreme heat inside the combustion chamber (5,000 degrees F) that works as a catalyst to permanently harden the material to make it stronger than the actual head gasket itself. Use on all water cooled gasoline and diesel engines. The heavy duty formula works on aluminum and cast iron heads and blocks, along with sealing all other engine cooling system leaks better than a traditional stop leak.
