K-Seal HD

K-Seal HD is a ceramic and copper formula that mixes with all types of anti-freeze to make permanent repairs to cooling systems on all larger capacity engines. K-Seal stops leaks in the engine’s block, head, radiator, heater matrix, freeze plugs and the head gasket by pouring the contents into the engine coolant. One 16 ounce bottle treats cooling systems of up to 50 quarts capacity.
