- A test probe available commercially and made available at petrol stations.
1. Regularly before the start of the winter season, the concentration of the antifreeze should be checked, especially if clean water was added before.
2. Warm up the engine until the upper coolant hose to the radiator is hand temperature.
3. Carefully open the lid of the expansion tank.
4. Fill the measuring probe with coolant and read the float of the probe. At the latitude of Germany, frost resistance should be up to -26°C, in areas with very cold climates up to -40°C.
Topping up with antifreeze concentrate
Warning! Use only branded ethylene glycol-based product with anti-corrosion properties. Antifreeze concentrate must be suitable for aluminum parts of the cooling system. Do not use alcohol-based antifreeze concentrate.

1. Close the cap on the expansion tank and after a test drive, check the frost resistance again.
