– Screw the adapter for cooling system testing device -
V.A.G 1274/8- to the coolant expansion tank.
– Assemble cooling system charge unit - VAS 6096- onto 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...1.0 MPa (6...10 bar)
– Open the valve -B-, while doing so turn the lever in the direction
of flow.
• A vacuum pump is created in the cooling system by the vac‐
uum pump; the display instrument pointer must move into 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 is -VAS 6096- 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-.
• If the display instrument pointer remains in the green area the
vacuum in the cooling system is sufficient for subsequent fill‐
ing.
Note
If the pointer is below the green area, repeat the process.
♦
If the vacuum drops, you must check the cooling system for
♦
leak points.
