COOLANT, FILLING WITH Cooling System Charge Kit - Electric Vacuum Pump :VAS6096/2: Notes

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

Special Tools And Workshop Equipment Required

Cooling System Charge Kit :VAS6096
Cooling System Charge Kit - Electric Vacuum Pump :VAS6096/2
Cooling System Charge Device :VAS6968
Cooling System Tester - Directional Valve :VAS691005/5
Shop Crane - Drip Tray :VAS6208
Refractometer :T10007A
Hose Clamps - Up To 25 mm :3094

Conditions:

The coolant was drained as described. Refer to DRAIN THE COOLANT .

NOTE:

Using the :VAS6096/2 will achieve a greater vacuum in the cooling system. The higher vacuum results in less air in the cooling system after filling. For this reason a >>shorter<< bleeding can be performed. Refer to Vehicle Diagnostic Tester.

CAUTION:

The engine could be damaged through uneven filling/bleeding of the coolant system.

The cooling system must be bleed after filling. Refer to Vehicle Diagnostic Tester.

-- Reconnect all coolant hoses that have been removed.

-- Attach the :VAS691005/5 -2- to the coolant expansion tank -1-.

-- Perform the check of the :VAS6096/2 . Refer to Cooling System Charge Kit - Electric Vacuum Pump .

-- Position the COOLING SYSTEM CHARGE DEVICE :VAS6968 so that it is higher than the coolant expansion tank -arrows- and fill it with at least 10 liters (2.64 gallons) of premixed coolant with the right mixture ratio. Pay attention to the coolant notes. Refer to COOLANT .

-- Connect the :VAS6096 as shown on the :VAS6968 .

Do not connect the : VAS6096 on the :VAS691005/5 yet. The filling hose must first be bled.

-- Bleed the hose -2- to do so quickly open the valve on the Coolant Reservoir and quickly open the valves -A- and -B-, until the hose -2- is filled with coolant.

-- Close the valves -A and B- by turning lever at a right angle to the flow direction.

-- Open the cap -1-.

-- Connect the :VAS6096 -1- on the test adapter -2-.

-- Connect the :VAS6096/2 on the vehicle battery and switch on. Open the valve -B-.

-- When vacuum extracting, make sure that the water separator -1- in the vacuum pump does not get full of coolant.

CAUTION:

Risk of damaging the :VAS6096/2 due to extracted coolant.

Make sure the :VAS6096/2 does not extract any coolant. If necessary, stop the procedure and evacuate the coolant expansion tank. Refer to COOLANT, FILLING WITH Cooling System Charge Kit - Electric Vacuum Pump .

-- Extract using the :VAS6096/2 until the needle on the pressure gauge -arrow- is well below the green area.

-- Close the valve -B- and switch off the :VAS6096/2 .

-- Watch the pressure gauge. The needle of the pressure gauge must not move.

-- When the conditions met, the cooling system can be filled. Refer to Cooling System, Filling .

When The Water Separator In The :VAS6096/2 is Filled with Coolant, the Coolant Expansion Tank Must Be Extracted:

-- Close the shut-off valve -B- and switch off the :VAS6096/2 .

-- Seal the supply hose -2- and the return hose -1- of the coolant expansion tank using the :3094 .

-- Remove the connector coupling -arrow- and open the shut-off valve -B- the coolant expansion tank is vented with this.

-- Remove the :VAS6096 and :VAS691005/5 .

-- Extract the coolant from the coolant expansion tank.

-- Reinstall the :VAS6096 and Test Adapter and remove the hose clamp.

-- Switch on the :VAS6096/2 and extract again.
