Remove

  1. Open LH front door, and Lower LH front window.
  2. Enable Service Mode Plus. See
  3. Unlock the vehicle gateway. See .
  4. 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 > Run, and allow the routine to complete.
  5. Disconnect the LV battery. See LV Power (Disconnect and Connect) (Modify).
  6. Remove the front aero shield panel. See Aero Shield - Front (Remove and Replace).
  7. Lower the vehicle to a comfortable working height.
  8. Position a fluid catcher underneath the front of vehicle.
  9. Remove the fresh intake duct. See Duct - Air Intake (Remove and Replace).
  10. Disconnect powertrain coolant pump connector.
  11. Remove bolts securing powertrain coolant pump to supermanifold.
    Tip
    Use of the following tool(s) is recommended:
    • Cordless Ratchet/Impact Driver
    • Torx T20 bit
  12. Remove powertrain coolant pump from Supermanifold.

Install

  1. Position powertrain coolant pump to Supermanifold for installation.
    Note
    Install new O-rings, lubricate both O-rings with silicone O-ring lubricant.
  2. Install bolts securing powertrain coolant pump to supermanifold.
    1.8 Nm (1.3 lbs-ft)
    Note
    Hold pump firmly in place with one hand while torquing down first two screws (star-pattern). Do not attempt to compress o-rings by torquing down the screws, as this could pinch the o-rings leading to a leak.
    Tip
    Use of the following tool(s) is recommended:
    • Cordless Ratchet/Impact Driver
    • Torx T20 bit
  3. Connect powertrain coolant pump connector.
  4. Install the fresh intake duct. See Duct - Air Intake (Remove and Replace).
  5. Remove fluid catcher from underneath vehicle.
  6. Raise vehicle fully and lower lift onto locks.
  7. Install the front aero shield panel. See Aero Shield - Front (Remove and Replace).
  8. Lower vehicle fully.
  9. Perform the cooling system (partial refill and bleed) procedure. See Cooling System (Partial Refill And Bleed) (Modify).
  10. Connect the LV battery. See LV Power (Disconnect and Connect) (Modify).
  11. Unlock the gateway. See Gateway (Unlock).
  12. Select Stop Thermal Fill/Drain > Run, and allow the routine to complete.
  13. Select Coolant Purge Start > Run, and allow the routine to complete.
    Note
    Make sure vehicle is not in Drive, shifting the vehicle into Drive will stop this routine. The test will last approximately 10 mins. The test will vary speeds from 3500-6500 RPM (idle speed = ~1500 RPM) and actuate the valve between series and parallel. If speed hovers at 7000 RPM, it indicates the pump is air locked, perform the vacuum fill again. Continue to add coolant and purge until the coolant level reaches between the NOM and MAX Lines on the bottle.
  14. Raise LH front window, and close LH front door.
  15. Remove the vehicle from the 2 post lift. See Raise Vehicle - 2-Post Lift.
