Coolant Mixture Ratio

WARNING: This page is about a different car, the 2023 Volkswagen Atlas. However, it is still accessible from the selected car via links, so may be relevant.

Coolant (40%) and distilled water (60%) for freeze protection down to -25 °C (-13 °F)
Coolant (50%) and distilled water (50%) for freeze protection down to -36 °C (-32.8 °F)
Refer to the appropriate Electronic Parts Information for the correct coolant.

-- Slide the coolant hose -1- at bottom on to the cooler connection and secure.

-- Connect the connector for the Engine Coolant Temperature Sensor -- radiator outlet on the coolant hose -1-.

-- Install the test adapter -2- (Cooling System Tester - Directional Valve:VAS 691 005/5 ) on the coolant expansion tank -1-.

-- Bleed the hose -2-.

-- For this open the valve on the Cooling System Charge Device VAS 6968 and 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 -1- (Cooling System Charge Device:VAS 6968 ) on the -2- (Cooling System Tester - Directional Valve:VAS 691 005/5 ).

CAUTION:

Risk of damaging the due to extracted coolant.

- Make sure the Electric Vacuum Pump does not extract any coolant. If necessary, stop the procedure and evacuate the coolant expansion tank. Refer to When the water separator in the is filled with coolant, the coolant expansion tank must be extracted: .

-- Use the Electric Vacuum Pump vacuum for approximately five minutes.

-- The needle on the pressure gauge -arrow- must move until it is well below the green range.

-- Close the valve -B- and switch off the Cooling System Charge Kit - Electric Vacuum Pump:VAS 6096/2 .

-- 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 .
