Smaller leaks caused by stone chips, porous solder joints and microcracks in the cooling system (detectable, for example, by a decrease in the coolant volume in the cooling system). The radiator leak stopper Stop Leak seals such leaks immediately and effortlessly. Prevents damage caused by the inflow of steam coolant into the combustion chamber.

For all liquid-based cooling and heating systems, regardless of the presence of a water filter. Also suitable for use in aluminum and plastic radiators. 250 ml is sufficient for up to 40 liters of coolant. Compatible with all common solvents, coolants and antifreeze additives. Can also be used as a preventative measure.
