    Note
    Select "X" at top right of window to close once complete, Thermal Fluid Fill/Drain routine has a 5 hour time limit, After 5 hours EXV's will close and routine must be performed again, Verify EXV positions are open VIA Garage >Thermal > Refrigerant loop EXV, Verify LCC, CC Left, Evap, CC Right, Chiller are all at ~100%. Recirc is at ~20%, LCC Solenoid is OPENED
  4. Disconnect 12V power. See 12V/LV Power (Disconnect and Connect).
  5. Perform the refrigerant system recovery. See A/C Refrigerant (Recovery and Recharge).
  6. Remove the bolt that attaches the supermanifold-to-compressor A/C line to the supermanifold.
    Tip: Use of the following tool(s) is recommended:
    • 13 mm socket
    • Flex head ratchet/flex head torque wrench
    • 6 in extension
  7. Remove the supermanifold-to-compressor A/C line from the supermanifold, and then hang it on the underhood storage unit support beam using an s-hook.
