Cooling System Draining And Vacuum Filling (G2131524): Filling

WARNING: This page is about a different variant/trim than selected.
  1. Install the front tow eye cover.

    Torque  : 7 Nm 

  2. Prepare a sufficient volume of coolant using a 50% mixture of premium cooling system fluid or equivalent, meeting specification WSS-M97B44-D and 50% water.
  3. CAUTION: Make sure the air ejecting from the vac fill tool is pointed away from the vehicle.
    NOTE:
    • Make sure the coolant volume in the container is greater than the amount of coolant the vehicle requires.
    • 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 special tools.

      Special Tool(s): JLR-303-1634  , HU-919 

    • Connect the hose from the vacuum refill adapter into a container of clean coolant, making sure the hose is submerged in coolant at all times during the fill operation.
    • 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 (-12 psi) Bar is shown on the gauge.

  5. G12005749Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC
    • Close the air supply valve.
    • Allow 1 minute to check the vacuum is held.

    Open the coolant supply valve and allow the coolant to be drawn into the system until the header tank is at least half full and no further fluid is entering the tank. If the fill process appears to stop and the header tank is not yet half full then stop the fill process, remove the tool and restart the cooling system draining and vacuum filling procedure.

  7. Remove the special tool adapters.
  8. Check and top-up the coolant to MAX.
  9. 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 the next step to bleed coolant from the bleed points.
  10. Remove the radiator grille.

    Refer to: RADIATOR GRILLE

    Release the front finisher and position to one side.

  12. G14286205Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Open the bleed screw, when coolant is visible from the outlet close the bleeding point.

    Torque  : 2 Nm 

  13. G12005708Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Open the bleed screw, when coolant is visible from the outlet close the bleeding point.

    Torque  : 2 Nm 

  14. G14285991Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Open the bleed screw, when coolant is visible from the outlet close the bleeding point.

    Torque  : 2 Nm 

  15. G12005709Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC
    • Reposition the front finisher in the correct location and install the retaining clip.
    • Install the 3 retaining bolts and tighten to the correct torque

      Torque  : 9 Nm 

  16. Install the radiator grille.

    Refer to: RADIATOR GRILLE

  17. G11588176Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC
    • Depressurize and remove the cooling system pressure tester.
    • Check and top-up the coolant to MAX.
  18. CAUTION: Correct installation of the coolant expansion tank cap can be obtained by tightening the cap until 3 audible clicks are heard.

    Install the coolant expansion tank cap.

  19. Connect exhaust extraction hoses to the tail pipes.
    • Select sand driving/dynamic mode if available.
    • Make sure the interior heater is switched off.
  21. Start and run the engine and allow to idle for 30 seconds.
  22. CAUTION: Make sure to observe the coolant level at all times and top up to the MAX mark as required.

    Hold the engine speed at 3500 rpm until the cooling fan starts to run and the thermostat opens, this will be evident as the radiator side coolant temperature will rise as coolant starts to flow around the radiator.

  23. Switch the engine off and allow the engine to cool.
  24. WARNING: Release the cooling system pressure by slowly turning the coolant expansion tank cap a quarter of a turn. Cover the expansion tank cap with a thick cloth to prevent the possibility of scalding. Failure to follow this instruction may result in personal injury.
    • Remove the coolant expansion tank pressure cap.
    • Maintain the coolant level in the coolant expansion tank at the MAX mark.
  25. CAUTION: Correct installation of the coolant expansion tank cap can be obtained by tightening the cap until 3 audible clicks are heard.

    Install the coolant expansion tank cap.
