COOLANT, FILLING WITH Cooling System Charge Kit - Electric Vacuum Pump:VAS 6096/2: Notes

Using the Cooling System Charge Kit - Electric Vacuum Pump :VAS 6096/2  will achieve a greater vacuum in the cooling system. The higher vacuum results in less air in the cooling system after filling.

Special tools and workshop equipment required 

• Cooling System Tester - Directional Valve :VAS 691 005/5 
• Vehicle Diagnostic Tester
• Cooling System Charge Device :VAS 6968  , if equipped

-- Connect the Cooling System Charge Kit :VAS 6096  as shown on the Cooling System Charge Kit :VAS 6968  .

• Do not connect the Cooling System Charge Kit : VAS 6096  on the Cooling System Tester - Directional Valve :VAS 691 005/5  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- on the Cooling System Charge Device :VAS 6968  .

-- Connect the Cooling System Charge Kit -1- on the test adapter -2-.
