- Coolant. Refer to the Parts Information.
-- Connect coolant hose and lower right coupling -3- to the radiator.
-- Fill the :VAS6096/1 on the :VAS6096 with at least 10 liters (10.5 quarts) 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-.
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 direction of flow.
- 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.
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 (CONVERTIBLE) / NOISE INSULATION, REMOVING AND INSTALLING (CONVERTIBLE) .
-- 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.
