    Note
    Make sure the routine is successful.
  5. Open the powered frunk.
  6. Remove the coolant bottle cap.
  7. Install vacuum refill tool onto coolant bottle assembly.
  8. Place empty coolant container into front storage area.

    Note
    If frunk is not installed take caution, CFM fan shroud assembly cannot support a full coolant container, Ensure overflow container is empty, Place fender cover over FEM and front fascia
  9. Fill container with at least 15L of coolant.
  10. Place filled coolant container onto coolant drain and fill cart.
    Informational PurposesAn informational icon, calling your attention

    Note
    If not already done, Verify refill valve is set to off.
  16. Open air inlet valve to draw a vacuum, Once gauge stabilizes, Fully close valve.
    Informational PurposesAn informational icon, calling your attention
    Note
    Gauge stabilizes roughly (60-70 cmHg), Vacuum should not drop after the valves are closed.
  17. Slowly open the refill valve to allow coolant to be drawn into the system.
    Informational PurposesAn informational icon, calling your attention
    Note

  28. Navigate to Service mode > Thermal > Actions to access the thermal system routines.
  29. Select "Start Coolant Air Purge" using the UI.
    Informational PurposesAn informational icon, calling your attention
    Note
    Touch time only, wait until coolant pumps stop running (audible noise), Routine Passed will appear, but pumps will run for 10 minutes, If you start next another routine during this time, it will fail, Make sure vehicle is not in "Drive", Routine is still running despite the completed message, Speeds can be monitored in garage under PT Thermal tab, Idle speed = ~1500 RPM, Test will vary speeds from 3500-6500 RPM and actuate valves between SERIES and PARALLEL, Putting vehicle into "Drive" will stop this routine, If speeds hover at 7000 RPM, this indicates the pumps are air locked, perform a vacuum fill, Continue to add coolant and purge until the coolant level reaches between the NOM and MAX Lines on the bottle
  30. Touch Thermal System Performance Test, touch Run, and allow the routine to complete.
  31. Inspect coolant level and top off as necessary.
