Remove
- Set up the AC machine.
- Remove the front aero shield. See Panel - Aero Shield - Front (Remove and Replace).
- Position a fluid catcher underneath the front of vehicle.
- Unlock the vehicle gateway. See Gateway (Unlock).
- On the touchscreen, tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap , and allow the routine to complete.
- Remove the HEPA filter assembly. See SERVICE KIT - HEPA AND CARBON FILTERS (Remove and Replace).
- Disconnect the LV battery. See LV Power (Disconnect and Connect).
- Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
- Remove the air intake duct, See Duct - Air Intake (Remove and Replace).
-
Recover the A/C refrigerant. See
A/C Refrigerant (Recovery and Recharge) (Maintenance).
WarningMake sure there is no pressure in the A/C system before performing the following steps. Failure to do so may result in damage to components and/or personal injury.WarningHFO-R1234yf and R134a are considered hazardous and, if handled incorrectly, can cause serious injury. Suitable personal protective equipment, consisting of face and eye protection, safety glasses, face shield, heat-proof gloves, chemical resistant gloves, rubber boots and apron or waterproof overall must be worn when carrying out operations on the air conditioning system.
-
Remove the bolt that attaches the
supermanifold-to-compressor A/C line to the supermanifold.
NoteUse of the following tool(s) is recommended:
- 13 mm socket
-
Remove the supermanifold-to-compressor
A/C line from the supermanifold, and move it aside.
NoteCarefully position the line so that oil does not drip out.
-
Release the locking tab, and then
disconnect the electrical connector from the chiller EXV.
CAUTIONDO NOT push down on the red locking tab. Pull the tab away from the connector until the connector is unlocked, and then continue pulling to release the connector.
- Use a pick to pull the locking tab downward, and then pull toward the front of the vehicle to remove the chiller EXV coil.
-
Remove the bolts (x4) that attach the
chiller to the supermanifold.
TIpUse of the following tool(s) is recommended:
- 8 mm socket
-
Slightly release the RH side of the
chiller from supermanifold and allow excess coolant to drain.
NoteLeave the A/C ports intact to supermanifold while coolant drains to avoid cross contamination.
- Remove the chiller from the vehicle.
- Remove and discard the chiller gasket from supermanifold.
Install
- Install a new chiller gasket into supermanifold.
-
Install the chiller to
supermanifold.
NoteLubricate the O-rings on the chiller with the appropriate A/C oil. See Fluids and Capacities for A/C oil specifications. Then hand tighten the bolts that attach the chiller to the supermanifold.
-
Torque the bolts (x4) that attach the
chiller to the supermanifold.8 Nm (5.9 lbs-ft)NoteTorque the bolts in the following sequence, as illustrated in the picture:TIpUse of the following tool(s) is recommended:
- 8 mm socket
- Use shop towels to wipe away any residue fluid.
-
Install the chiller EXV coil onto the
expansion valve.
NoteProperly align the expansion valve coil locking tab to the supermanifold. Perform a push pull push test on the expansion valve coil to ensure the coils is properly latched.
-
Connect the electrical connector of
the chiller EXV.
CAUTIONPush the red locking tab towards the connector to engage the locking mechanism. DO NOT push down or pull up on the red locking tab.
- Install new seal washers on the supermanifold side of the supermanifold-to-compressor A/C line, and then lubricate the washers with a small amount of the appropriate A/C oil. See Fluids and Capacities for A/C oil specifications.
- Position the supermanifold to compressor A/C line onto the supermanifold, and then hand-tighten the bolt that attaches the A/C line to the supermanifold.
-
Tighten the bolt that attaches the
supermanifold to compressor A/C line to the supermanifold.22 Nm (16.2 lbs-ft)NoteUse of the following tool(s) is recommended:
- 13 mm socket
- Perform the vacuum leak test and oil injection, and A/C refrigerant recharge. See A/C Refrigerant (Recovery and Recharge) (Maintenance).
- Perform a cooling system vacuum refill. See Cooling System - Vacuum Refill.
- Remove the fluid catcher from underneath the front of the vehicle.
- Connect the LV battery. See LV Power (Disconnect and Connect).
- Unlock the vehicle gateway. See Gateway (Unlock).
-
On the touchscreen, perform the
following steps.
- Install the front aero shield. See Panel - Aero Shield - Front (Remove and Replace).
- Install the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
-
Inspect the coolant level and top off
as necessary, and then install the coolant bottle cap.
NoteEnsure that the coolant level is at the "Max" line.NoteIf the coolant loss is greater than 1L, vacuum refill is required to perform.
- On the touchscreen, tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap , and close once the routine is passed.
- Exit Service Mode. See Service Mode.
- Install the cabin intake duct. See Duct - Air Intake (Remove and Replace).
- Install the HEPA filter assembly. See SERVICE KIT - HEPA AND CARBON FILTERS (Remove and Replace).
