Liqui Moly’s Radiator Stop Leak is a product that can help seal small leaks caused by stone chipping, porous soldered connections, or hairline cracks in the cooling system on water-cooled engines. The dispersion contained in this product completely seals this type of leak immediately and safeguards the combustion chamber against damage caused by coolant ingress. It is suitable for aluminum radiators, prevents negative side effects on the water pump or heating circuit, and is compatible with conventional coolants and antifreezes.
