    TIp
    Use of the following tool(s) is recommended:
    • Pick Miniature Soft Grip, 90 degree tip, 6 in
  13. Use a clip pry tool to release the retaining clip that attaches the A/C compressor logic harness to the A/C compressor HV harness bracket.
  14. Move thermal harness from supermanifold to side.
  15. Use a pick to pull the locking tab downward, and then pull toward the front of the vehicle to remove the EXV coil.

Install

  1. Install the EXV coil onto the expansion valve.
    Informational PurposesAn informational icon, calling your attention
    Note
    Slide the coil seal onto the expansion valve. Do not lubricate the coil seal. Properly align the expansion valve coil locking tab to the supermanifold. Slide the expansion valve coil over the coil seal. Perform a push pull push test on the expansion valve coil to ensure the coils is properly latched.
  2. Route thermal harness back to supermanifold.
  3. Install the retaining clip that attaches the A/C compressor logic harness to the A/C compressor HV harness bracket.
  4. Connect the A/C compressor logic electrical connector to the A/C compressor, and then engage the locking tab.
