Solv-Tec’s K-Seal HD features a ceramic/copper formula that mixes with all types of anti-freeze. Just shake the bottle and add the contents to the engine coolant in any gas or diesel engine.
K-Seal will stop most leaks in the block, head, radiator, heater matrix, freeze plugs and the head gasket within minutes, the company said. One 16-ounce bottle treats cooling systems up to 50 quarts in capacity. List price is $14.99 per 16-ounce bottle.
