Correcting anticorrosion/antifreeze concentration

 Warning

Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.

Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.

Calculation table for refill quantity

A

Determined anticorrosion/antifreeze agent concentration

B

Coolant fill quantity, total

C

Calculated refill quantity

Shown is a sample calculation for the refill quantity for ENGINE 651

1

Enter determined anti-corrosion agent and antifreeze concentration (A) in the calculation table.

 According to the comparison table, a measured antifreeze protection of up to -20 °C corresponds to a determined anticorrosion agent and antifreeze concentration (A) of 32 vol. %.
For a total coolant fill quantity (B) of approx. 8.5 l, the calculated refill quantity amounts to (C) 2.25 l.

2

Take total coolant fill quantity (B)   from the basic data table and enter into the calculation table.

3

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

4

Drain off the calculated refill quantity (C) from the coolant at drain valve   on radiator.

5

Fill the calculated refill quantity (C) of the corrosion protection agent and antifreeze into the expansion reservoir.

6

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