Cooling System Partial Draining And Vacuum Filling (G2259014): Filling

WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install the engine undershield.

    Refer to: ENGINE UNDERSHIELD - PROJECT 8

  2. Prepare a sufficient amount of coolant to the specified concentration.

    Refer to: SPECIFICATIONS 

  3. NOTE:
    • Make sure the coolant supply valve is in the closed position on the special tool.
    • The special tool needs an air pressure of 6 to 8 bar (87 to 116 psi) to operate correctly.
    • Small diameter or long airlines may restrict airflow to the coolant vacuum fill tool.

    • Install the coolant system vacuum refill kit.

      Special Tool(s): HU-919 

    • Position the hose from the vacuum refill adapter into a container of clean coolant.
    • Connect a regulated compressed air supply to the venturi tube assembly.
    • Install the cooling system vacuum refill adapter to the expansion tank.
  4. NOTE:
    • Make sure the coolant supply valve is in the closed position on the vacuum filler gauge assembly.
    • The coolant vacuum fill tool needs an air pressure of 6 to 8 bar (87 to 116 psi) to operate correctly.
    • Small diameter or long airlines may restrict airflow to the coolant vacuum fill tool.

    Open the air supply valve until -0.8 Bar is shown on the gauge.

  5. G11287816Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC
    • Close the air supply valve.
    • Allow 1 minute to check the vacuum is held.
  6. NOTE: Close the coolant supply valve when the coolant expansion tank 'MAX' mark is reached or coolant movement has stopped.

    Open the coolant supply valve and allow the coolant to be drawn into the system.

  7. Remove the special tool.
  8. CAUTION:
    • Make sure that the mating faces are clean and free of foreign material.
    • Do not exceed 1.0 bar (15 psi) when pressurizing the cooling system.
    NOTE: If the pressure continues to drop after the initial tolerance, there is a coolant leak.

    • Using the correct adapter connect the cooling system pressure test kit to the vehicle expansion tank.
    • Slowly pressurize the cooling system until the pressure gauge reads 1.0 bar (15 psi).
    • Make sure the cooling system holds pressure, and continue to step 9 to bleed coolant from the bleed points.
  9. NOTE:
    • Make sure the hood is open.
    • Make sure the engine is not running.
    1. Switch the Ignition ON and select the park position (car in Parking (P) or Neutral (N) mode).
    2. Open the driver's door.
    3. Fully press the accelerator pedal for 10 seconds.
    4. Fully release the accelerator pedal.
    5. Electric coolant pump will be activated for 5 minutes.
    6. Monitoring the engine coolant level in the engine coolant expansion tank.
    7. After 5 minutes, increase the system pressure until 1 bar is showed in the gauge, if needed.
  10. Connect exhaust extraction hoses to the tail pipes.
  11. Start and run the engine.
  12. Set the heater controls to 'MAX'.
  13. Install the coolant expansion tank cap.
  14. Hold the engine speed at 2000 rpm until warm air is expelled from the heater.
  15. Switch the engine off and allow to cool.
  16. Clean any spilt coolant from the vehicle.
  17. WARNING: Since injury such as scalding could be caused by escaping steam or coolant, allow the vehicle cooling system to cool prior to doing this procedure.

    Check and top-up the coolant if required.
