Liqui Moly Radiator Stop Leak

This Liqui Moly Radiator Stop Leak is formulated for sealing leaks in the cooling water circuits of water-cooled engines. It effectively seals hairline cracks and smaller leaks and can also be used preventively after a cooling system repair. The solids dispersion is stabilised in a carrier fluid - shake well before use. Add the contents to the cold cooling system, start the heater, and drive the vehicle for at least 10 minutes.

A 150 ml bottle treats up to 10 litres of coolant, ensuring a reliable seal and preventing further leaks.
