A/C Line - Supermanifold to HVAC (Remove and Replace)

Correction code 18201702 0.48 NOTE: Unless otherwise explicitly stated in the procedure, the above correction code and FRT reflect all of the work required to perform this procedure, including the linked procedures. Do not stack correction codes unless explicitly told to do so.NOTE: See Flat Rate Times to learn more about FRTs and how they are created. To provide feedback on FRT values, email LaborTimeFeedback@tesla.com. NOTE: See Personal Protection to make sure wearing proper PPE when performing the below procedure.

  • 2024-09-29: Updated the UI routines.
  • 2024-09-12: Added note on adding correction code for refrigerant - recovery/recharge as a separate activity to the Service Visit.
  • 2024-02-28: Updated the routines.

Remove

  1. Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
  2. Unlock the vehicle gateway. See Gateway (Unlock).
  3. On the touchscreen, tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap Thermal > Refrigerant System > Start Thermal Fill Drain (Refrigerant only) > Run, and allow the routine to complete.
  4. Disconnect 12V power. See 12V/LV Power (Disconnect and Connect).
  5. Recover the A/C refrigerant. See A/C Refrigerant (Recovery and Recharge).
  6. Remove the fresh intake duct. See Duct - Fresh Intake (Remove and Replace).
  7. Remove the 12V/LV auxiliary battery. See 12V/LV Battery (Remove and Replace).
  8. Remove the bolts (x2) that attach the supermanifold to HVAC A/C line to the HVAC assembly.
    Tip: Use of the following tool(s) is recommended:
    • 13 mm socket
    • 6 in extension
    • Flex head ratchet/flex head torque wrench
  9. Remove the nut that attaches the supermanifold to HVAC A/C line to the supermanifold.
    Tip: This nut is behind the supermanifold to compressor A/C line.
    Tip: Use of the following tool(s) is recommended:
    • 13 mm socket
    • 6 in extension
    • Flex head ratchet/flex head torque wrench
  10. Release the supermanifold to HVAC A/C line from the supermanifold, and then move the A/C line rearwards and up to remove it.

Install

  1. Position the supermanifold to HVAC A/C line on the supermanifold, inserting the A/C line stud into the stud hole on the supermanifold.
