– Set up cooling system charging device -VAS 6968- -F- so
that it is positioned higher than coolant expansion tank
-arrows-.
Important
•
The cooling system charging device must contain at least
10 litres of coolant mixed in proper ratio.
– Bleed hose -G-. To do this, open shut-off tap on cooling sys‐
tem charging device -F- and shut-off tap -A- until hose -G- is
filled with coolant and air has been displaced completely.
– Close shut-off tap -A-.
– Open cap -1-.
Filling cooling system
– Fit cooling system charge device -VAS 6096- -1- onto adapt‐
er -2-.

– Connect electric vacuum pump -VAS 6096/2- -D-. To do this,
fit hose -E- onto plug-in connector -B- on cooling system
charging device -C-.
– Connect electric vacuum pump -D- to battery -A-, and switch
it on.
– Open shut-off tap -B-.
NOTICE
Risk of damage to electric vacuum pump from coolant being
drawn in.
– Make sure that the electric vacuum pump does not draw
in coolant. Drain coolant from the coolant expansion tank
beforehand.
– If the water separator -1- in the electric vacuum pump is fil‐
led with coolant during the following procedure, drain coolant
from the coolant expansion tank ⇒ page 73 .
– Using the electric vacuum pump, generate vacuum until nee‐
dle of pressure gauge -arrow- is significantly below green
area.
