Remove

  1. Remove the HEPA duct assembly. See Duct - HEPA (Remove and Replace).
  2. Disconnect 12V power. See 12V/LV Power (Disconnect and Connect).
  3. Remove the font aero shield panel. See Panel - Aero Shield - Front (Structural Pack) (Remove and Replace).
  4. Recover the A/C refrigerant. See A/C Refrigerant (Recovery and Recharge).

    Note
    Recover the refrigerant while continuing this procedure.
  5. Connect AC hoses to vehicle.
  6. Remove bolt on supermanifold to compressor AC line from supermanifold.
  7. Use a tie strap to fix the compressor AC line, and then keep it from Supermanifold.
  8. Disconnect the electrical harness from the chiller and EXV assembly connector.
  9. Remove electronic expansion valve chiller coil.
  10. Remove the bolts (x3) that attach the chiller and EXV assembly to the supermanifold, and then remove the chiller and EXV assembly.
  11. Remove and discard the o-rings from the suction/liquid line fitting.

Install

  1. Install a new o-rings to the suction/liquid line fitting.
  2. Install the chiller and EXV assembly to the supermanifold, and then install the bolts (x3) that attach the chiller and EXV assembly to the supermanifold.
    8 Nm (5.9 lbs-ft)
  3. Install electronic expansion valve chiller coil.
  4. Connect the electrical harness to the chiller and EXV assembly connector.
  5. Replace seal washers for supermanifold to compressor AC line on supermanifold side.
    22 Nm (16.2 lbs-ft)
  6. Install supermanifold to compressor AC line onto supermanifold.
  7. After installing the assembly, refill the refrigerant. See A/C Refrigerant (Recovery and Recharge).

    Note
    Perform installation of components removed concurrently with refrigerant refill.
  8. Remove AC hoses from vehicle.
  9. Install caps (X2) onto AC ports.
  10. Remove the coolant drain from under the vehicle.
  11. Install the font aero shield panel. See Panel - Aero Shield - Front (Structural Pack) (Remove and Replace).
  12. Connect 12V power. See 12V/LV Power (Disconnect and Connect).
  13. After the A/C refrigerant recharge has fully completed, verify the operation of the A/C system.
  14. Refill the coolant to the proper level. See Cooling System (Partial Refill and Bleed)
  15. Install the HEPA duct assembly. See Duct - HEPA (Remove and Replace).
