C Replenished quantity of anticorrosion/antifreeze agent in liters
N20.00-0376-04
Example calculation
Measured value:
20 °C antifreeze, corresponds to an anticorrosion/antifreeze concentration (A) of 32 Vol.%.
Total filling capacity of the coolant (B) 41 liters.
Calculated refill quantity (C) 10.85 liters of anticorrosion-/antifreeze.
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 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 engine and run for about 1 minute at varying revs
