Coolant, Filling
-- Fill the coolant reservoir from the :VAS6096 with 10 liters of premixed coolant in the correct mixture ratio. Refer to Coolant Mixture Ratio for the mixture ratio.
-- Install the :VAG1274/8 on the coolant expansion tank.
-- Attach the :VAS6096 to the :VAG1274/8 .
-- Place the drain hose -1- in a small container -2-.
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 -3- to compressed air.
- Pressure: 7 to 10 bar (101.52 to 145 psi) positive pressure.
-- Open the coolant circuit valves and select 01 - Coolant Circuit Bleeding in Guided Functions Vehicle Diagnostic Tester.
-- Open valve -B- by turning level in direction of flow.
- The suction jet pump generates pressure in the coolant system; indicator on display instrument must move into green area.
-- Briefly open valve -A- by turning lever in direction of flow so that hose on the :VAS6096 coolant reservoir fills with coolant.
-- Close valve -A- again.
-- Leave 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 green area.
-- Close 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 Pressurized Air Hose.
-- Open 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 :VAG1274/8 on coolant expansion tank.
-- Connect the :VAG1274/10 to the :VAG1274/8 .
-- Fill the :VAG1274/10 with coolant. Fill again during the bleeding procedure if required.
