- VERSATILE APPLICATION. Works across various engine and cooling system components: gaskets, radiators, blocks, heads, heater cores, freeze plugs, and intake manifolds.

Hi-Gear products' cooling system additives have set a new standard for quality and performance in the automotive industry. As new technology evolves and is introduced by original equipment manufacturers, the product that maintain and treat equipment need to evolve as well. Hi-Gear Products' research and development experts are constantly upgrading formulations and offering new and innovative products. Shop technicians and consumers rely on Hi-Gear Insta-Seal. Insta-Seal seeks out the low pressure area formed by cracks and holes and deposits the ceramic micro-fibers and copper as it flows through the crack. Within seconds the crack or hole is completely filled and the seal is complete. Engine heat further welds the seal so that it will last the life of the engine. Insta-Seal fixes both large and small leaks in plastic, aluminum and cast iron intakes, heads, blocks and radiators. Safely use Insta-Seal with all types of antifreeze including conventional green or blue (silicate-based) and extended life red/orange or yellow (OAT/HOAT) coolants. Insta-Seal will not harm the cooling system when used properly. Insta-Seal quickly and effectively seals leaks in gasoline and diesel cars, trucks, vans, SUVs and RVs. Compatible with all types of glycol-based coolants.
