Liqui-Moly Radiator Stop-Leak - 250mL

Product Details

It’s not easy to find small leaks caused by stone chipping, porous soldered connections or hairline fractures in the cooling system on all water-cooled engines – the only clue is in the reduced coolant level. Radiator Sealant seals these types of leaks completely, easily and in an instant and safeguards the combustion chamber against damage caused by coolant ingress.

Application: Shake well before use. Add contents to the cold cooling system. Start up the engine. Then drive the vehicle for at least 10 minutes. Contents will treat up to 10 liters of coolant (dosage 1:66).
