Coolant, Draining And Filling: Procedure

WARNING: This page is about a different car, the 2015 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

-- Connect the coolant hoses to the connection on the radiator, refer to Figure.

-- Connect the coolant hoses, refer to CONNECTION DIAGRAM - COOLANT HOSES .

-- Fill the coolant reservoir on the Cooling System Charge Kit VAS 6096 with at least 8 liters of premixed coolant with the proper mixture ratio.

-- Install the Cooling System Tester - Adapter VAG 1274/8 on the coolant expansion tank.

-- Mount the Cooling System Charge Kit VAS 6096 on the Cooling System Tester - Adapter VAG 1274/8.

-- Place the air outlet hose -1- in a small container -2-.

NOTE: A small amount of coolant which should be collected is drawn off with the discharged air.

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

-- Connect the hose -3- to compressed air.

Pressure: 6 to 10 bar (87 to 145 psi) pressure.

-- Open valve -B- by turning level in direction of flow.

A further vacuum is created in the cooling system by the suction jet pump.
Needle on the instrument display must travel into the green region.

-- Briefly open valve -A- by turning lever in direction of flow so that hose on the Cooling System Charge Kit VAS 6096 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.

NOTE:

Repeat the procedure if the needle goes below the green range.

If pressure falls, check coolant system for leaks.

-- Remove pressurized air hose.

-- Open 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 from the coolant reservoir.

-- Fill the coolant to the MAX marking.

NOTE: The hose connections as well as the air guide pipes and hoses must be free of oil and grease before installing.

-- Install the noise insulation, refer to Exterior Equipment .

-- If the vehicle has a parking heater, switch it on for about 30 seconds.

-- Set the temperature at "HI".

-- Press AC to turn off the A/C compressor.

The LED in the button must not come on.
