– Fill up the coolant reservoir of the -VAS 6096- with at least 10
litres of pre-mixed coolant mixed to the correct ratio:
– Screw the adapter for the cooling system testing device , e.g.
-V.A.G 1274/8- onto the coolant expansion tank.
– Connect the cooling system charge unit - VAS 6096- with the
adapter -V.A.G 1274/8- .
– Lead the air hose -1- into a small container -2-.
Note
A small amount of coolant, which is entrained with the exhaust
air, must be collected.
– Close the valves -A- and -B-, while doing so turn the lever at
right angles to the direction of flow.
– Connect hose -3- to compressed air.
• Pressure: 0.6 -1 MPa (6...10 bar) overpressure.
– Open the valve -B-, while doing so turn the lever in the direction
of flow.
• Vacuum is generated in the cooling system by the suction jet
pump. The display instrument pointer must be in the green
area.
– In addition, briefly open the valve -A- by turning the lever in the
direction of flow, so that the hose of the coolant expansion
bottle of the -VAS 6096- is filled with coolant.
– Close the valve -A- again.
– Leave the valve -B- open a further 2 minutes.
• A vacuum pump is created in the cooling system by the vac‐
uum pump; the display instrument pointer must remain in the
green area.
– Close the valve -B-.
• The display instrument pointer must remain unaffected in the
green area. The vacuum in the cooling system is now sufficient
for subsequent filling.
Note
If the pointer is below the green area, repeat the process.
♦
If the vacuum drops, check the cooling system for leak points.
♦
– Disconnect pneumatic hose.
– Open valve -A-.
• The vacuum pump in the cooling system draws the coolant out
of the coolant reservoir -VAS 6096- and fills the cooling sys‐
tem.
– Remove the cooling system charge unit - VAS 6096- from the
coolant expansion tank.
