Radiator Sealant is a dispersion for sealing leaks in water-cooling systems in motor vehicles. The product reliably seals hair cracks and small leaks. The solids dispersion is stabilised in carrier fluid. Small leaks caused by stone impacts, porous soldering points and hairline cracks in the cooling simple are easy to localize (one notices that the cooling water level is sinking). LIQUI MOLY Radiator Stop-Leak completely seals such leaks immediately with ease. Secures the combustion chamber from damages caused by coolant admission.
