This procedure is a DRAFT, although it has been validated. Warnings and Cautions might be missing. Follow safety requirements and use extreme caution when working on or near high voltage systems and components. Provide corrections and feedback to ServiceDevelopment@teslamotors.com.
  1. If necessary, perform a platter enclosure coolant drain. See Platter Enclosure Coolant (Drain) (On Table).
  2. Attach the coolant leak test adapter to the HV battery inlet fitting.

  4. Connect the pressure test fixture hose to the leak test adapter.
  5. Turn valves P1 and P2 to the closed (vertical) positions.
  6. Turn the knob on the regulator to the fully closed setting.
  7. Connect the supply compressed air line to the pressure test fixture.
  8. Turn valve P1 to the open (horizontal) position and slowly adjust the regulator so that 50 psi is displayed on the gauge.
  9. Slowly turn valve P2 to the open (horizontal) position and allow air to enter the system.
  10. Allow 60 seconds for the pressure to stabilize.
  11. Turn valve P1 to the close (vertical) position.
  12. Record the beginning pressure value and start a 3 minute timer.
  13. After 3 minutes has elapsed, record the end pressure value, and then substract the end pressure value from the beginning pressure value.
    • If the pressure difference is more than 0.8 psi, inspect for leaks, turn valve P2 to the close (vertical) position, and retest from step 8.
    • If the pressure difference is 0.08 psi or less, continue to the next step.
  14. Disconnect the supply compressed air line from the pressure test fixture.
  15. Slowly turn valve P1 to the open (horizontal) position, and allow air to exit the system.
  16. Disconnect the pressure test fixture hose from the coolant leak test adapter.
  17. Remove the coolant leak test plug from the HV battery outlet fitting.
  18. Remove the coolant leak test adapter from the HV battery inlet fitting.
