Carlube Radiator Sealer stops leaks in the cooling system and remains active to stop possible later leaks. Safe for radiators, coils and gaskets. Contains corrosion inhibitors.

Instructions for use: Let the engine run until the engine warms up. Carefully remove the coolant cap. Pour the leak stopper into the radiator or expansion tank and start the engine. The leak will stop as the engine warms up. Wash the cooling system of an old and large-bore engine with a cooling system internal cleaner before using the leak stopper.
