LIQUI MOLY Radiator Stop Leak 250 ml is a dispersion for the water-based cooling systems of water-cooled engines. Added straight into the coolant, it seals small leaks, hairline cracks and porous soldered joints that are hard to trace — often the only sign is a dropping coolant level. Supplied in a 0.250 L can.
