WARNING: This page is about a different variant/trim than selected.

-- Reconnect all coolant hoses that have been removed.

-- Fill the coolant reservoir on the :VAS6096 with at least eight liters (2.11 gallons) of premixed coolant with the correct mixture ratio. Pay attention to the coolant notes. Refer to COOLANT .

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

-- Connect the :VAS6096 on the :VAG1274/8 .

-- Place the drain hose -2- in a small container -3-.

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 -4- to compressed air.

Pressure: 6 to 10 bar (87.02 to 145.03 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.

-- Briefly open valve -A- by turning the lever in the flow direction so that the coolant reservoir hose on the :VAS6096 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 leaks if the pressure drops.

-- 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 the coolant to the MAX marking.
