B Coolant fill quantity, total

C Calculated refill quantity

N20.00-2001-04

Shown on calculation example of refill quantity

1 Enter the calculated anticorrosion/antifreeze concentration (A) in the calculation table.

 According to the comparison table, a measured antifreeze up to 20 °C corresponds to an anticorrosion/antifreeze agent concentration (A)

of 32 % by volume.

At a coolant fill quantity, total (B)

of 8.5 l the calculated refill quantity (C) corresponds to 2.25 l.

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

3 Work out the calculated refill quantity (C) of the anticorrosion/antifreeze agent using the calculation table.

4 Drain a quantity of coolant corresponding to the calculated refill quantity (C) at the radiator drain plug.

5 Pour in the calculated refill quantity (C) of antifreeze/antifreeze agent into the cooling system.

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