Procedure 

• Used coolant cannot be used again.

-- Fill the coolant reservoir from the Cooling System Charge Kit :VAS 6096  with 10 liters of coolant with the correct mixture ratio. Refer to Coolant Mixture Ratio  for the mixture ratio.

-- 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.

-- Install the Cooling System Tester - Adapter:V.A.G 1274/8  on the coolant expansion tank -1-.

-- Attach the Cooling System Charge Kit:VAS 6096  on the Cooling System Tester - Adapter :V.A.G 1274/8  .

-- 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 to 10 bar (101.53 to 145.04 psi) positive pressure.

-- Open the coolant circuit valves. Refer to Vehicle Diagnostic Tester 0001 - Engine Electronics Functions  , 0001 - Coolant Circuit Bleeding Procedure  .

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

• The suction jet pump generates vacuum 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 Cooling System Charge Kit :VAS 6096  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.

• 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 Cooling System Charge Kit :VAS 6096  coolant reservoir by pressure in the coolant system and the system is filled.

-- Remove the Cooling System Charge Kit:VAS 6096  and the Cooling System Tester - Adapter :V.A.G 1274/8  from the coolant expansion tank.

Continuation of the filling procedure:

-- Bleed the cooling system. Refer to BLEED COOLING SYSTEM. .
