Example calculation
Measurement obtained:
20° C antifreeze protection, equals an anticorrosion/antifreeze agent concentration (A) of 32 % by vol.
Total coolant capacity (B) 41 liters
Calculated replenished quantity (C) 10.85 liters of anticorrosion/antifreeze agent
1 Enter the calculated anticorrosion/antifreeze concentration (A) in the calculation table.
2 Read the total coolant capacity (B) from the basic data table and enter it in the calculation table.
3 Calculate the top-up quantity of anticorrosion/antifreeze agent (C).
4 Drain the calculated top-up quantity of coolant (C) at the drain plug on the radiator.
5 Pour the calculated top-up quantity of anticorrosion/antifreeze agent (C) into the cooling system.
6 Start the engine and run at alternating speeds for about 1 minute.
