Cooling System Partial Draining And Vacuum Filling (G2166874): Filling

WARNING: This page is about a different variant/trim than selected.
  1. Prepare a sufficient amount of coolant to the specified concentration.

    Refer to: SPECIFICATIONS 

  2. 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.

      Special Tool(s): HU-919 

    • Connect 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.

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

  6. Remove the vacuum filler gauge and cooling system vacuum refill adapter assembly.
  7. Check and top-up the coolant to MAX.
  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  10 to bleed coolant from the bleed points.

    • 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 

  15. G11588176Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC
    • Depressurize and remove the cooling system pressure tester.
    • Check and top-up the coolant to MAX.
  16. 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.

  17. Connect exhaust extraction hoses to the tail pipes.
    • Start and run the engine at idle.
    • Set the heating system to MAX heat, the blower motor to MAX speed and the air distribution to the instrument panel registers.
    • Select sand mode on the terrain response. This will assist in degassing air from the system.
  19. Continue fill the vehicle with coolant until the it reaches the maximum mark on the coolant expansion tank.
    • Install the coolant expansion tank cap.
    • Install the coolant expansion tank to its original position.

      Torque  : 9 Nm 

  21. When hot air is emitted from the heater vents, switch off the heater.
  22. CAUTION: Observe the engine temperature warning indicator. If the warning indicator is displayed, switch off immediately and allow to cool. Failure to follow this instruction may cause damage to the vehicle.

    Increase the engine speed between 2000 rpm for 17 minutes.

  23. Switch the engine off.
