B Total coolant capacity in liters
C Replenished quantity of anticorrosion/ /antifreeze agent in liters
N20.00-0376-04
Example for calculation
Measured value: 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 replenished quantity of anticorrosion/antifreeze agent (C).
4 Drain the calculated replenished quantity of coolant (C) at the drain plug of the radiator.
5 Fill calculated replenished quantity of anticorrosion/antifreeze agent (C) into the cooling system
6 Start engine and run at alternating rotational speeds for approx.1 minute
7 Inspect coolant level
