TIP: 

Coolant, Filling With Cooling System Charge Kit - Electric Vacuum Pump:VAS6096/2  . Refer to COOLANT, FILLING WITH COOLING SYSTEM CHARGE KIT - ELECTRIC VACUUM PUMP .

• Ignition switched off.
• To make the filling procedure easier, position the coolant reservoir as high up as possible, for example on a workshop cart or the engine and gearbox jack.

-- Fill the coolant reservoir on the :VAS6096  with at least eight liters of premixed coolant with the proper mixture ratio.

-- Install the :VAG1274/8  on the coolant expansion tank -1-.

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

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

TIP: 

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

-- 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.
• 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 the coolant to the MAX marking.

-- Install the noise insulation. Refer to NOISE INSULATION, REMOVING AND INSTALLING / OVERVIEW - NOISE INSULATION .
