Application area

Seals hairline cracks in radiator, engine block or cylinder head. Leaking hose connections can also be sealed. Permanent sealing of hairline cracks and leakage points protects the cooling circuit and combustion chamber from leaks. Radiator sealant prevents loss of coolant.


Shake the can well before use. Add the contents of the can to the warm cooling system. Open the radiator valves and let the engine run for at least 10 minutes. Check the coolant level and leak tightness again. In trucks, use a mixing ratio of maximum 1:100.
