Major cooling system leaks, including those in radiators, heater cores, intake manifolds and blocks, can cost thousands of dollars to repair. For large leaks, little time and less money, Rislone has the solution. The Solution: Rislone Liquid Copper Block Seal and Radiator Stop Leak stops major cooling system leaks, including those in gaskets, radiators, heater cores, blocks, heads and freeze plugs. Liquid Copper (p/n 31109) uses an advanced antifreeze-compatible sodium silicate liquid glass formula so no draining of the cooling system is required.

It works with all types and brands of antifreeze, including conventional green or blue (silicate-based) and extended life red/orange or yellow (OAT/HOAT) coolant. Liquid Copper stops leaks by forming a physical seal using organic and synthetic fibers, copper and an ionic-modified mineral. The seal forms as the coolant and product flow through the leak. A wetting agent cleans the sides of the hole or crack to prepare the surface for bonding.

The first fibers catch on the side of the leak, building on each other to bridge the entire hole. The fibers then act as a sieve to trap more fibers, copper particles and minerals to create a composite seal. The seal is cemented with liquid glass.

As the temperature increases, the liquid glass hardens to make the seal permanent. Liquid Copper will not harm the cooling system when properly installed, nor will it clog the cooling system or heater core. Rislone Liquid Copper can be used in any water-cooled vehicle, including cars, trucks, vans, SUVs and RVs.
