    Note
    Plug bypass powertrain hose on both ends to prevent excess coolant drain.

Install

  1. Install bypass powertrain hose to vehicle.
  2. Install clip securing bypass powertrain hose to RH side of front subframe.
  3. Install bypass powertrain hose to supermanifold.

    Note
    Perform push-pull-push test to make sure hose is fully seated.
  4. Position coolant drain container underneath RH front of HV battery.
  5. Connect powertrain return hose to powertrain return tube and plug hoses.

    Note
    Perform push-pull test to verify hoses are fully engaged. If the coolant loss is greater then 1L, vacuum fill will be required. See Cooling System - Vacuum Refill.
  6. Remove coolant drain container from underneath vehicle.
  7. Release RH front wheel liner from bungee strap.
  8. Install the push clip and bolt that attach the RH front wheel arch liner to the skid plate.

    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.
  15. Inspect the coolant level and top off as necessary, and then install the coolant bottle cap.

    Note
    Ensure that the coolant level is at the "Max" line.
  16. Install the HEPA filter assembly. See Service Kit - Hepa And Carbon Filters (Remove and Replace).
  17. Install the rear aero shield panel. See Underhood Apron - Rear (Remove and Replace).
