Table for calculating top-up quantity
of anticorrosion/antifreeze agent
A Concentration of anticorrosion/antifreeze agent determined
(in % by vol.)
B Coolant filling quantity, total
(in liters)
C Refill quantity of anticorrosion/
antifreeze (in liters)
N20.00-0376-04
Example calculation
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 replenished quantity of anticorrosion/antifreeze agent (C)
4 Drain coolant in the calculated refill quantity of anticorrosion/antifreeze agent (C) at the radiator drain plug.
5 Pour the calculated top-up quantity of anticorrosion/antifreeze agent (C) into the cooling system.
6 Start engine and run for about 1 minute at varying speeds.
Example calculation
Measured value = - 20 °C antifreeze protection, according to the above table this corresponds to a determined anticorrosion/
antifreeze concentration (A) of 32 % by volume.
Total filling capacity of the coolant (B) 41 liters.
Calculated replenished quantity of the anticorrosion/antifreeze agent (C)
= 10.85 liters.
