This seals because of the extreme heat inside the combustion chamber (5000°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. Heavy duty formula works on aluminum and cast iron heads & blocks, along with sealing all other engine cooling system leaks better than a traditional stop leak. This includes repairing head gaskets, cylinder heads, intake gaskets, cracked blocks and freeze plugs. Use with ALL types of antifreeze including conventional green or blue.
