4 cyl. petrol engine (1.8 l and 2.0 l with direct injection, 4 V, exhaust gas turbocharger, timing chain,
Filling with coolant:
– Open valve -B- by setting lever in direction of flow.
• The suction jet pump generates a vacuum in the cooling sys‐
tem. The display instrument needle must move to the green
area.
– Also briefly open valve -A- (turn lever in direction of flow to do
this) so that hose on -VAS 6096- coolant reservoir fills with
coolant.
– Close the valve -A- again.
– Leave valve -B- open for 2 further minutes.
• The suction jet pump will continue generating a vacuum in the
cooling system. The pointer of the indicator must remain in the
green zone.
– Close valve -B-.
• The needle on the gauge must stay in the green zone. Then
the vacuum in the cooling system is sufficient for the subse‐
quent filling.
Note
If the needle does not reach the green zone, repeat the proc‐
♦
ess.
If vacuum drops, cooling system must be checked for leaks.
♦
The subsequent filling must be performed »slowly«.
♦
– Pull off compressed air hose.
– Open valve -A- slowly.
• Vacuum in cooling system causes coolant to be extracted from
-VAS 6096- coolant reservoir and coolant system to be filled.
• The coolant level must be above the max. marking after filling.
– Detach cooling system charge unit - VAS 6096- from coolant
expansion tank.
– Fill coolant up to max. mark.
