Warning
Wear appropriate personal protective equipment (PPE) including a full face mask when performing this procedure.
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.
  1. Open the LH front door and lower the LH front window.
  2. Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
  3. Enable Service Mode. See Service Mode.
  4. Unlock the vehicle gateway. See Gateway Unlock.
  5. On the touchscreen, tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap Thermal > Coolant System > Coolant Fill/Drain, click Run, and then allow the routine to complete.
  6. Disconnect the LV battery power. See LV Battery - Li-lon (Disconnect and Connect).
  7. Remove the cap from the coolant bottle.
  8. Place an empty coolant container and a container with at least 15L coolant in the front underhood storage.
  9. Attach the vacuum refill tool cap to the coolant bottle, and make sure that all valves on the refill tool are in the closed position.
  10. 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 engaged.
  11. Place the end of the overflow hose of the vacuum refill tool into the empty container.
  12. Place the refill hose inside the filled coolant container and make sure the end of the hose is fully submerged in the coolant.
  13. Connect the supply air line to the vacuum refill tool.
    Informational PurposesAn informational icon, calling your attention
    Note
    Make sure that the refill valve is set to off.
  14. Open the air inlet valve to vacuum the cooling system. Once the gauge is stabilized, fully close the valve.
    Informational PurposesAn informational icon, calling your attention
    Note
    The vacuum should stabilize at approximately -70 to -60 cmHg and should not drop after the valves are closed.
  15. Slowly open the coolant refill valve to draw coolant into the coolant refill hose. Close the valve when the hose is full of coolant.
  16. Monitor the gauge for 30 seconds to verify that vacuum is maintained in the cooling system.
  17. Open the air inlet valve for 3 minutes to continue evacuating the cooling system, and then close the valve.
  18. Slowly open the coolant refill valve to draw coolant into the cooling system. Once the gauge reads zero, close the valve.

    Note
    Make sure the end of the coolant refill hose is fully submerged during the entire process.
  19. Disconnect the supply air line from the tool.
  20. Remove the coolant refill hose and the coolant overflow hose from the coolant container.
  21. Remove the vacuum refill hose from the refill cap on the coolant bottle, and then remove the whole vacuum refill tool from the vehicle.
  22. Remove both coolant containers from the vehicle.
  23. Connect the LV battery power. See LV Battery - Li-lon (Disconnect and Connect).
  24. On the touchscreen, tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap Thermal > Refrigerant System > Stop Thermal Fill Drain, and then allow the routine to complete.
  25. Select Thermal > Coolant System > Coolant Purge, click Run, and then allow the routine to complete.
    Informational PurposesAn informational icon, calling your attention
    Note
    • The routine will last for a while after the stop message displays. The coolant pumps are audible.
    • The test lasts for approximately 10 mins. Do not start another routine during this time.
    • Make sure that the vehicle is not in Drive. Putting the vehicle into Drive will stop this routine.
    • The speed in the test varies from 3500-6500 RPM (idle speed = ~1500 RPM) and the actuated valve varies between SERIES and PARALLEL.
    • If the speed hovers at 7000 RPM, it indicates the pumps are air locked. Perform the vacuum fill again. Continue to add the coolant and purge until the coolant level reaches between the NOM and MAX Lines on the bottle.
  26. Inspect the coolant level, top off as necessary, and then install the coolant bottle cap.
    Informational PurposesAn informational icon, calling your attention
    Note
    Ensure that the coolant level is at the "Max" line.
  27. On the touchscreen, tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap Thermal > Actions, then click the START button next to Test Thermal Performance, click Run, and allow the routine to complete.
  28. Select the START button next to Test HVAC Performance, click Run, and then allow the routine to complete.
  29. Install the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
  30. Raise the LH front window and close the LH front door.
