The LIQUI MOLY Radiator Stop Leak is a dispersant that will fix any leaks and keep you from worrying about a sudden overheating.

Common Problems



LIQUI MOLY Radiator Stop Leak should be a part of every mechanic’s toolbox. Why? It’s hard to locate small leaks caused by stone chipping, porous soldered connections or hairline cracks in the cooling system on water-cooled engines – the only clue is in the reduced coolant level. This dispersion completely seals this type of leak immediately and safeguards the combustion chamber against damage caused by coolant ingress. Compatible with all conventional coolant additives and approved for both fresh and heavily contaminated liquid.
