    Note
    Remove any debris that may have built up. Allow 1 minute of dry time.

    CAUTION
    Make sure that there are no empty gaps in the grease application.
  3. Make sure to only use new umbrella valves. Refer to image for how to identify new parts.
  4. Inspect the new umbrella valves for proper assembly.
    Informational PurposesAn informational icon, calling your attention
    Note
    Reject any incorrectly assembled parts. Only use reworked parts if they match the “Good” requirements. To check if the thermal vent is properly pre-assembled, rotate the umbrella around the clamp. If it rotates smoothly without any resistance, the installation is correct. If there is any resistance, even slight, the installation is incorrect. To fix it, push the umbrella more firmly onto the clamp.
  5. Install the new umbrella valves (x5) into the HV Battery.
    Informational PurposesAn informational icon, calling your attention
    Note
    Push the valve into the thermal vent opening with the legs facing inward. Confirm all three legs are clipped into the opening with an audible click. Push the umbrella into HV battery enclosure after verification.
  6. Perform the HV battery leak test. See HV Battery Air Leak Test (In Vehicle).
    Warning IconA warning icon, calling your attention to a possibly risky situation
    CAUTION
    While the HV battery is pressurized, inspect each umbrella valve for escaping air. Perform the following test regardless of leak test results.
    • Place a hand over each umbrella valve to feel for escaping air.
    • Spray soapy water over each umbrella valve and inspect for bubbles.

    If leaks are found, replace the umbrella valve as needed.

    If no leaks from any of the umbrella valves are found, but the HV battery leak test is failing, refer to Toolbox article 5402000 for further diagnoses.

  7. Install the mid aero shield panel. See Panel - Aero Shield - Rear (Remove and Replace).
  8. Remove the vehicle from the lift. See Raise Vehicle - 2 Post Lift.
  9. Install the RH rocker panel molding. See Molding - Rocker Panel - LH (Remove and Replace).
  10. Close the doors and raise the windows.
