Radiator Stop-Leak

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.
