Warning
Wear appropriate personal protective equipment (PPE) including a full face mask when performing this procedure.
  1. Informational PurposesAn informational icon, calling your attention
    Note
    It is important that the drive rails remain off throughout this procedure. If the drive rails become active, such as from touching the brake pedal, an error is displayed in Toolbox. If this happens, you must disable the drive rails, and repeat the step where the error occurred.
  2. If 12V power has been reconnected, verify on the vehicle touchscreen that the system is in Fill/Drain mode. If the vehicle is not in Fill/Drain mode, activate Fill/Drain mode and verify that the green status indicator is present.
    Informational PurposesAn informational icon, calling your attention
    Note
    The status indicator will be red if the mode is inactive.
  3. Remove the cap from the coolant bottle.
  4. Place an empty coolant container in the front underhood storage.
  5. Set a container having at least 15 L of coolant in front underhood storage.
  6. Place the vacuum refill tool coolant refill hose inside the filled coolant container and make sure the end of the hose is fully submerged in the coolant.
  7. Attach the vacuum refill cap to the coolant bottle.
  8. Make sure that coolant refill valve and air inlet valve on the vacuum refill tool are both closed.
  9. Install the vacuum refill hose into the refill cap on the coolant bottle.
    Informational PurposesAn informational icon, calling your attention
    Note
    Perform a push-pull test to verify that the hose is fully installed.
  10. Place the end of the overflow hose of the vacuum refill tool into the empty container.
  11. Connect the supply air line to the vacuum refill tool and make sure the minimum pressure is 5.5 bar (80 psi).
  12. Open the air inlet valve and allow the tool to evacuate the cooling system for 10 seconds, and then fully close the valve.
    Informational PurposesAn informational icon, calling your attention
    Note
    The vacuum should stabilize at approximately -27 to -24 inHg or -70 to -60 cmHg.
  13. Slowly open the coolant refill valve to draw coolant into the coolant refill hose. Close the valve when the hose is full of coolant.
  14. Monitor the gauge for 30 seconds to verify that vacuum is maintained in the cooling system.
  15. Open the air inlet valve for 3 minutes to continue evacuating the cooling system, and then close the valve.
  16. Slowly open the coolant refill valve to draw coolant into the cooling system. When the gauge reaches zero, close the valve.
    Informational PurposesAn informational icon, calling your attention
    Note
    Make sure the end of the coolant refill hose is fully submerged during the entire process.
  17. Disconnect the supply air line from the tool.
  18. Remove the coolant refill hose from the coolant container.
  19. Remove the coolant overflow hose from the coolant container.
  20. Remove the vacuum refill hose from the refill cap on the coolant bottle.
  21. Remove the vacuum refill cap from the coolant bottle.
    Informational PurposesAn informational icon, calling your attention
    Note
    Push down on the black ring to release the hose, and then pull the hose upward to remove it.
  22. Lift the coolant refill tool above the coolant container to allow excess coolant to drain from the hoses.
    Informational PurposesAn informational icon, calling your attention
    Note
    Reopen the valves to remove excess coolant if necessary.
  23. Remove both coolant containers from the vehicle.
  24. Reconnect 12V power. See12V/LV Power (Disconnect and Connect).
  25. Connect to the vehicle with a laptop with Toolbox 3.0.
  26. In Toolbox, click the Actions/Autodiag tab, and then search for "Purge".
