-- Fill the :VAS6096/1 on the :VAS6096 with at least 10 liters (10.56 quart) of coolant.

-- Use the proper mixture ratio of coolant.

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

-- Mount the :VAS6096 on 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 valves -A and B- by turning lever at a right angle to the flow direction.

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

Pressure: 6 to 10 bar (87 to 145 psi) positive pressure.

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

A further vacuum is created in the cooling system by the suction jet pump.
The needle on the instrument display must travel into the green region.

-- Open the valve -A- slightly for a moment.

-- To do this, turn the lever in the direction of flow so that the :VAS6096/1 hose fills with coolant.

-- Close the valve -A- again.

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

A further vacuum is created in the cooling system by the suction jet pump.
Needle on the instrument display must still remain in the green region.

-- Close the valve -B-.

The needle on display must remain in the green range.
Only then is there enough vacuum in the coolant system for the filling.

NOTE:

Repeat the procedure if the needle goes below the green range.

Check the cooling system for leak if the pressure drops.

-- Remove the pressure hose.

-- Open the valve -A-.

The vacuum in the cooling system causes coolant to be extracted from the :VAS6096/1 and to fill the cooling system.

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

-- Fill up the coolant expansion tank -1- with coolant to the "max" marking -arrow-.

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

-- If the vehicle has a parking heater, switch it on for about 30 seconds.

-- Set the temperature at "HI".

-- Press AC 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 cap on the coolant expansion tank until it locks into place.

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

-- Turn off engine and allow it to cool off.

-- Check The Coolant Level In The Coolant Expansion Tank -1-.

The coolant level must be between the "min" and "max" markings when the engine is cold.
The coolant level may be at the "max" marking -arrow- when the engine is warm.

-- Add more coolant if necessary.
