  • 2024-04-24: Removed the thermal test steps and updated the way of performing the routines from using Toolbox to using the touchscreen.

Remove

  1. Place the vehicle on the 2-post lift.
    Tip: Ensure the vehicle is not charging.
  2. Open the LH front door and lower the LH front window.
  3. Place the vehicle in Service Mode by using the touchscreen. See Service Mode (Enable and Disable).
  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 > Start Thermal Fill/Drain, click Run, and allow the routine to complete.
  6. Remove the underhood storage unit. See Underhood Storage Unit (Remove and Install).
  7. Disconnect the LV battery power. See LV Power (Disconnect and Connect).
  8. Remove the LV battery. See Battery - LV (Remove and Replace).
  9. Remove the front body controller module. See Module - Body Controller - Front (Remove and Replace).
  10. Remove the front aero shield panel. See Panel - Aero Shield - Front (Remove and Replace).
  11. Place a coolant catcher below the RH front of vehicle.
  12. Lower the vehicle until the tires are touching the ground.
  13. Place absorbent material on the top of the front drive unit and under the coolant hoses at rear of the supermanifold.
  14. Disconnect the sensor for the powertrain supply hose.
  15. Disconnect the powertrain supply hose from supermanifold, and plug the ends of fittings as soon as possible to avoid coolant loss.
  16. Disconnect the low pressure PT sensor connector and release the harness from supermanifold.
  17. Release the clips (x2) that attach the thermal harness to the supermanifold.
  18. Release the connectors (x2) that attach the thermal harness to the powertrain coolant pump and the chiller coolant pump, and then move the harness away from the rear of supermanifold.
  19. Remove the screws (x4) that attach the chiller coolant pump to the supermanifold.
    Tip: Use of the following tool(s) is recommended:
    • Mini Ratchet Bit Set
  20. Remove the chiller coolant pump from the supermanifold.
    Informational PurposesAn informational icon, calling your attention
    Note
    Make sure both o-rings (inner purple, and outer black) come off with the old pump.

Install

  1. Lubricate both O-rings with silicone lubricant.
  2. Align the datum of supermanifold with the slot of the chiller coolant pump, then seat the pump fully into the supermanifold.
    Warning IconA warning icon, calling your attention to a possibly risky situation
    CAUTION
    Do not use screws to force the pump into the supermanifold.
  3. Install the screws (x4) that attach the chiller coolant pump to the supermanifold.
    1.8 Nm (1.3 lbs-ft)
    Tip: Use of the following tool(s) is recommended:
    • Mini Ratchet Bit Set
  4. Route the thermal bar harness between the powertrain coolant pump and the chiller coolant pump, then secure the connectors (x2) that attach the thermal harness to the powertrain coolant pump and the chiller coolant pump.
  5. Secure the clips (x2) that attach the thermal harness to the supermanifold.
  6. Secure the harness to supermanifold, and connect the low pressure PT sensor connector.
  7. Remove the plugs on the ends of fittings, and then connect the powertrain supply hose to the supermanifold.
    Informational PurposesAn informational icon, calling your attention
    Note
    Perform a push-pull-push test to make sure that the hose is fully secured.
  8. Connect the sensor for the powertrain supply hose.
  9. Remove the absorbent material which is on the top of the front drive unit and under the coolant hoses at rear of the supermanifold.
  10. Clean the area and wipe away any residual fluid.
  11. Remove the front body controller module. See Module - Body Controller - Front (Remove and Replace).
  12. Perform a cooling system vacuum refill. See Cooling System (Vacuum Refill).
  13. Install the LV battery. See Battery - LV (Remove and Replace).
  14. Connect the LV battery power. See LV Power (Disconnect and Connect).
  15. Unlock the vehicle gateway. See Gateway (Unlock).
  16. On the touchscreen, perform the following steps:
    1. Touch Service Mode > Thermal > Coolant System > Stop Thermal Fill/Drain, click Run, and allow the routine to complete.
    2. Touch Service Mode > Thermal > Coolant System > Pump Identification, click Run, and allow the routine to complete.
    3. Touch Service Mode > Thermal > Coolant System > Coolant Air Purge, click Run, and 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.
  17. Install the front aero shield panel. See Panel - Aero Shield - Front (Remove and Replace).
  18. Hold the B-pillar button in the down position to manually calibrate the LH and RH falcon wing doors.
  19. 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.
  20. Install the underhood storage unit. See Underhood Storage Unit (Remove and Install).
  21. Raise the LH front window and close the LH front door.
