Calculated anticorrosion/

antifreeze agent concentration in % by vol.

B

Total coolant capacity in liters

C

Refill quantity of anticorrosion/

antifreeze agent in liters

Correcting anticorrosion/antifreeze concentration

Example of calculation:
Measured antifreeze protection 20 °C = 32 percent by volume. Determined corrosion protection/antifreeze protection concentration in percent by volume (A),
Total coolant capacity in liters (B) = 8.5 l
Calculated refill quantity of anticorrosion/antifreeze agent in liters (C) = 2.25 l.

1

Enter the calculated anticorrosion/antifreeze concentration in percentage by volume (A) in the calculation table.

2

Read total coolant capacity in liters (B) from basic data table and enter in calculation table.

3

Determine calculated refill quantity of anticorrosion/antifreeze agent in liters (C).

4

Drain coolant in the calculated refill quantity of anticorrosion/ antifreeze agent in liters (C) at the radiator drain plug.

5

Fill in the calculated refill quantity of anticorrosion and antifreeze agent in liters (C) into the cooling system.

6

Start engine and run for about 1 minute at varying speeds.
