Procedure
- Set up the A/C machine.
- Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
- Unlock the vehicle gateway. See Gateway Unlock.
- On the touchscreen, touch Run to start the "Start Thermal Fill Drain (Refrigerant Only)" routine. and select
- Recover the A/C refrigerant. See A/C Refrigerant (Recovery and Recharge) (Maintenance).
- Perform the vacuum leak test and refill A/C refrigerant. See A/C Refrigerant (Recovery and Recharge) (Maintenance).
-
Add 5 ml UV dye.
NoteAdd the dye with the refrigerant and oil.
- Remove the A/C hoses from the vehicle.
- On the touchscreen, touch Run to start the routine. and select

- Exit Service Mode through UI. See Service Mode.
- Set the temperature to LO on both driver and passenger HVAC controls and set the A/C system to AUTO.
- Run the A/C system for 10 minutes to allow the dye to circulate.
-
Use UV light and the UV inspection kit
to check for A/C refrigerant leaks near the HVAC end of the Supermanifold to HVAC A/C
line.
NoteIf an A/C refrigerant leak is found, replace the A/C line from supermanifold to HVAC. See Assembly - A/C Line - Supermanifold to HVAC (Remove and Replace).
-
Use UV light and the UV inspection kit
to check for A/C refrigerant leaks at the A/C low and high pressure port.
NoteIf an A/C refrigerant leak is found, replace the A/C line from supermanifold to HVAC. See Assembly - A/C Line - Supermanifold to HVAC (Remove and Replace).
-
Use UV light and the UV inspection kit
to check for A/C refrigerant leaks at the supermanifold area.
NoteIf an A/C refrigerant leak is found, replace the defective component.
-
Use UV light and the UV inspection kit
to check for A/C refrigerant leaks on the A/C compressor discharge and suction lines
area.
NoteIf an A/C refrigerant leak is found, replace the supermanifold to compressor A.C line. See Assembly - A/C Line - Supermanifold to Compressor (Remove and Replace).
-
Use UV light and the UV inspection kit to check for A/C refrigerant leaks on the
supermanifold.
NoteIf an A/C refrigerant leak is found, replace the defective component.
- Remove the front aero shield. See Panel - Aero Shield - Front (Remove and Replace)
-
Use UV light and the UV inspection kit to check for A/C refrigerant leaks near the
Supermanifold end of the Supermanifold to HVAC A/C line.
NoteIf an A/C refrigerant leak is found, replace the A/C line from supermanifold to HVAC. See Assembly - A/C Line - Supermanifold to HVAC (Remove and Replace).
- Install the front aero shield. See Panel - Aero Shield - Front (Remove and Replace)
- Install the caps (x2) back onto the A/C ports.
- Install the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
