Procedure

  1. Disconnect LV power. See LV Power (Disconnect and Connect).
  2. Raise vehicle fully and lower lift onto locks.
    Informational PurposesAn informational icon, calling your attention
    Note
    Set vehicle to comfortable working height, Make sure there's an audible click of the locks on both sides before lowering, otherwise vehicle may tilt to the side.
  3. Remove the front aero shield panel. See Panel - Aero Shield - Front (Remove and Replace).
  4. Remove the front skid plate. See Skidplate - Front (Remove and Replace).
  5. Pull the red locking tab out, and then pull the tab again to disconnect the electrical harness from the HV battery logic connector.
  6. Pull the red locking tab out, and then disconnect the electrical harness from the HV battery LV connector.
  7. Position a coolant drain collector under the front of the vehicle to catch the vehicle coolant.
  8. Release the clip and disconnect the 3 way valve to HV battery hose from the HV battery, and then immediately plug the fittings.
  9. Release the clip and disconnect the HV battery coolant supply hose from the HV battery, and then immediately plug the fittings.
  10. Release the clip and disconnect the power conversion system coolant supply hose from the HV battery, and then immediately plug the fittings.
  11. Release the clips (x2) on the LH front wheel arch liner, and then move the liner aside for access.
  12. Release the clips (x2) that attach the power conversion system coolant return to LH sill hose to the body.
  13. Release the clip and disconnect the power conversion system coolant return to LH sill hose from the LH sill hose, and then immediately plug the fittings.
  14. Remove the plug from the power conversion system coolant supply fitting, immediately connect the power conversion system flush adapter to the fitting, and then perform Push-Pull-Push test of the fittings.
  15. Connect the coolant cart flush hose to the coolant cart regulator.
  16. Make sure that the coolant cart regulator valve is in the closed (vertical) position.
  17. Connect the coolant cart flush hose to the power conversion system flush adapter.
    Informational PurposesAn informational icon, calling your attention
    Note
    Verify regulator valve is closed, Pressure regulator is not adjustable (set at 20 psi).
  18. Make sure that the power conversion system drain adapter valve is in the closed (perpendicular to adapter) position.
  19. Remove the plug from the power conversion system coolant return to LH sill hose fitting, immediately connect the power conversion system drain adapter to the fitting, and then perform a Push-Pull_Push test of the fittings.
  20. Connect the coolant cart drain hose to the coolant drain container.
  21. Connect the coolant cart drain hose to the power conversion system drain adapter.
  22. Turn the valve on the power converison system drain adapter to the open (parallel to adapter) position.
  23. Connect the supply air hose to the coolant cart supply air connector.
  24. Slowly turn the pressure regulator valve to the open (horziontal) position, and allow coolant to drain out of the power conversion system.
  25. After the coolant has drained, turn the pressure regulator valve to the closed (vertical) position.
  26. Disconnect the supply air hose from the coolant cart supply air connector.
  27. Turn the valve on the power conversion system drain adapter to the closed (perpendicular to adapter) position.
  28. Remove the coolant cart drain hose from the power conversion system drain adapter.
  29. Remove the coolant cart drain hose from the coolant drain container.
  30. Release the clip, and then disconnect the power conversion system drain adapter from the power conversion system coolant return to LH sill hose fitting.
  31. Disconnect the coolant cart flush hose from the power conversion system flush adapter.
  32. Disconnect the coolant cart flush hose from the coolant cart regulator.
  33. Release the clip, and then disconnect the power conversion system flush adapter from the power conversion system coolant supply fitting.
  34. Position the coolant drain collector under the front of the vehicle to catch the vehicle coolant.
  35. Remove the plugs from both fittings and immediately connect the power conversion system coolant return to LH sill hose to the LH sill hose, fasten the clip, and perform a Push-Pull-Push check of the fittings.
  36. Fasten the clips (x2) that attach the power conversion system coolant return to LH sill hose to the body.
  37. Return the LH front wheel arch liner to the LH front wheel arch, and then fasten the clips (x2) that attach the liner to the wheel arch.
  38. Remove the plugs from both fittings and immediately connect the power conversion system coolant supply hose to the HV battery, fasten the clip, and perform a Push-Pull-Push check of the fittings.
  39. Remove the plugs from both fittings and immediately connect the HV battery coolant supply hose to the HV battery, fasten the clip, and perform a Push-Pull-Push check of the fittings.
