-- Fill with coolant reservoir from the :VAS6096 with 10 liters (10.56 quarts) of coolant with the correct mixture ratio. Refer to COOLANT, DRAINING AND FILLING for the mixture ratio.

-- Install the :VAG1274/8 on the coolant expansion tank.

-- Attach the :VAS6096 to the :VAG1274/8 .

-- Place the drain hose -1- in a small container -2-.

NOTE:

A small amount of coolant which should be collected is drawn off with the discharged air.

-- Close the valves -A and B- by turning lever at a right angle to the flow direction.

-- Connect the hose -3- to compressed air.

Pressure: 7 to 10 bar (101.52 psi to 145.03 psi) positive pressure.

-- Open the coolant circuit valves and select 01 - coolant circuit bleeding in Guided Functions . Refer to Vehicle Diagnostic Tester.

-- Open the valve -B- by turning the lever in the flow direction.

The suction jet pump generates pressure in the coolant system; indicator on display instrument must move into green area.

-- Briefly open the valve -A- by turning the lever in the flow direction so that the hose on the :VAS6096 coolant reservoir fills with coolant.

-- Close the valve -A- again.

-- Leave the valve -B- open another two minutes.

More pressure is generated in the coolant system by the suction jet pump; indicator on display instrument must stay in the green area.

-- Close the valve -B-.

Needle in the display instrument must remain in the green region, then the sufficient vacuum in the cooling system is obtained for the upcoming filling.

NOTE:

If the needle stands below the green area, repeat the procedure.

If the pressure falls, check the coolant system for leaks.

-- Remove the pressure hose.

-- Open the valve -A-.

Coolant is extracted from the :VAS6096 coolant reservoir by pressure in the coolant system and the system is filled.

-- Remove the :VAS6096 from the coolant expansion tank.

-- Fill with coolant up to "max" marking.

-- Install the noise insulation. Refer to NOISE INSULATION .

-- Set the temperature to "HI".

-- Press the AC button to turn off the A/C compressor.

The LED in the button must not come on.

-- Start the engine and run it at approximately 1500 RPM for a maximum of two minutes.

-- With engine running, fill coolant up to overflow hole on coolant expansion tank.

-- Close the coolant expansion tank cap -arrow- until it locks into place.

-- Let the engine run at idle until both large coolant hoses on the radiator are warm.

-- Turn off the engine.
