Drain

  1. Disconnect 12V power. See 12V Power (Disconnect and Connect).
  2. Remove the front HV battery skid plate. See Skid Plate - HV Battery - Front (Remove and Replace).
  3. Remove the lower clips (x3) that attach the lower rear edge of the RH wheel arch liner to the body, to allow access to the coolant hose.
  4. Position a coolant drain under the front RH corner of the HV battery.
  5. Disconnect the rear powertrain supply hose at the RH side of the vehicle, plug the male fitting, and allow the female fitting to drain.
  6. Connect the coolant pressure test adapter to the female fitting.
  7. Connect the drive unit pressure test fixture to the coolant pressure test adapter.
  8. Close both valves P1 (inlet) and P2 (outlet) on the test fixture, and connect a compressed air supply line.
  9. Fully close the regulator, and then open P1 (inlet valve).
  10. Set the pressure regulator of the test fixture to 26 psi.
  11. Disconnect the powertrain return hose at the RH side of the vehicle, plug the female fitting, and allow the male fitting to drain.
  12. Connect the coolant drain adapter to the male connector, and direct the tube to the coolant drain.
  13. Slowly open P2 (outlet valve) to speed the drain.
  14. Wait at least 5 minutes for the coolant to fully drain.
  15. Close P2 (outlet valve) when no more coolant is expelled.
  16. Disconnect the air supply from the test fixture.
  17. Remove the coolant pressure test adapter and coolant drain adapter from the hoses
  18. Perform the service procedures that required the powertrain coolant to be drained.
  19. After the components have been replaced, refill the coolant. See Refill.
