Compressor (Remove and Replace)
Correction code 18203912 1.02 NOTE: Unless otherwise explicitly stated in the procedure, the above correction code and FRT reflect all of the work required to perform this procedure, including the linked procedures. Do not stack correction codes unless explicitly told to do so.NOTE: See Flat Rate Times to learn more about FRTs and how they are created. To provide feedback on FRT values, email LaborTimeFeedback@tesla.com. NOTE: See Personal Protection to make sure wearing proper PPE when performing the below procedure.
- 2023-05-02: Added steps to remove/install NVH acoustic cover.
- 2023-06-20: Added compressor weight including oil for Sanden type compressor.
- 2024-01-30: Removed the A/C flush-related steps and updated the way of performing the routines from using Toolbox to using the touchscreen.
- 2024-03-04: Updated the description of the oil amount calculation steps.
Only
technicians who have been trained in High Voltage Awareness and
have completed all required certification courses (if applicable) are permitted to
perform this procedure. Proper personal protective equipment
(PPE) and insulating HV gloves with a minimum rating
of class 0 (1000V) must be worn at all times a high voltage
cable, busbar, or fitting is handled. Refer to Tech Note TN-15-92-003, High Voltage Awareness
Care Points

Remove
- Remove the HEPA assembly. See Assembly - Filter - HEPA (Remove and Install).
- Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
- Place the vehicle in Service Mode by using the touchscreen. See Service Mode.
- 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.
- Perform Vehicle HV Disablement Procedure. See Vehicle HV Disablement Procedure.
-
Recover the A/C refrigerant. See A/C Refrigerant (Recovery and Recharge).
NoteRecover the refrigerant while continuing this procedure.
- Remove the LV battery. See 12V/LV Battery (Remove and Replace).
-
Remove the nut that attaches the low
pressure fitting to the A/C compressor.
Tip: Use of the following tool(s) is recommended:
- 13 mm deep socket
- Flex head ratchet/flex head torque wrench
-
Remove the nut that attaches the high
pressure fitting to the A/C compressor, and then set the hose assembly aside.
Tip: Use of the following tool(s) is recommended:
- 13 mm deep socket
- Flex head ratchet/flex head torque wrench
- Remove the compressor bracket. See Bracket - Compressor (Remove and Replace).
- Note the part numbers and serial numbers of the old and new A/C compressors.
-
Use masking tape to protect the LP and
HP opening ports on the compressor.
NoteMake sure the ports are fully covered.
- Use a flat scraper blade to remove the NVH acoustic cover from the compressor.
-
Use a wire brush to remove as much NVH cover material from the compressor
as possible.
CAUTIONFailure to remove material will result in an inaccurate weight measurement.
-
Use a digital scale to weigh the removed compressor and record its weight. Check the
dry weight on the label of the removed compressor, then subtract the dry weight from the
total weight to calculate the remaining oil amount. Record the remaining oil
amount.
NoteDo not drain any oil from the removed compressor.
- Repeat steps 14 and 15 to remove the NVH acoustic cover from the new compressor.
Install
-
Remove the transport plugs from the new compressor.
Tip: Use of the following tool(s) is recommended:
- 13mm socket
- Check the dry weight on the label of new compressor, then add it to the old compressor remaining oil amount calculated in step 16 to gain a target new compressor weight.
- Drain oil from the new compressor until the total weight match the target weight calculated in step 2.
- Install the NVH acoustic cover onto the new compressor.
- Install the compressor bracket. See Bracket - Compressor (Remove and Replace).
-
Replace the o-rings on the high
pressure and low pressure supermanifold to A/C compressor hose fittings.
-
Position the supermanifold to A/C
compressor high pressure fitting on the A/C compressor, and then install the nut that
attaches the fitting to the A/C compressor.Tip: Use of the following tool(s) is recommended:
- 13 mm deep socket
- Flex head ratchet/flex head torque wrench
-
Position the supermanifold to A/C
compressor low pressure fitting on the A/C compressor, and then install the nut that
attaches the fitting to the A/C compressor.Tip: Use of the following tool(s) is recommended:
- 13 mm deep socket
- Flex head ratchet/flex head torque wrench
- Connect the A/C machine red high pressure hose to the vehicle's high pressure port, and the blue low pressure hose to the vehicle's low pressure port.
- Perform A/C vacuum leak test and oil injection. See A/C Refrigerant (Recovery and Recharge).
- Install the low pressure A/C hose to supermanifold to HVAC A/C line assembly.
- Perform A/C recharge. See A/C Refrigerant (Recovery and Recharge).
- Install the LV battery. See 12V/LV Battery (Remove and Replace).
- Reconnect LV power. See 12V/LV Power (Disconnect and Connect).
- Redeploy firmware. See .
-
