Detailed specifications


  • Bring the engine up to operating temperature
  • Shake the bottle vigorously! Pour the agent into the radiator box with the engine switched off
  • Start the engine and let it idle for 5-10 minutes with the cabin heater on
  • To prevent possible leaks in the cooling system, the agent can be used immediately after changing the coolant



When the engine is hot, the antifreeze in the cooling system is under pressure. Please be careful when opening the radiator cap: hot coolant or steam may escape and injure you.


1 bottle (250 ml) of the agent is sufficient for 10-12 liters of coolant.
