Shake bottle well before use. Cool down the engine and unscrew cap of the cooling system. 250 ml WAGNER Radiator Stop Leak are sufficient for about 12-15 litres of cooling liquid.
CAUTION! Dosing always depends on the cooling system´s filling capacity,
Overdosage must be avoided in any case. Half of the can´s volume (125 ml) are sufficient for 5 – 7 litres of filling capacity.
Now start the car heater. While the engine is running, Radiator Stop Leak is slowly added to the radiator expansion tank, so that the agent gets evenly distributed in the cooling system circuit and settle at the spots to be sealed (leaks).
To ensure an even distribution of Radiator Stop Leak in the cooling system circuit, drive about 5 km.
When dosed correctly, there are no incompatibilities with antifreeze agents in the cooling system circuit.
