Tesla Model S: Compressor (Dual Motor) (RHD) (Remove and Replace)
Warning: Only technicians who have been trained in High
Voltage Awareness are permitted to perform this procedure. Proper
personal protective equipment (PPE) and insulating HV gloves with a
minimum rating of class 00 (500V) must be worn any time a high
voltage cable is handled. Refer to Tech Note TN-15-92-003, "High
Voltage Awareness Care Points" for additional safety information.
Removal
- Recover refrigerant from the vehicle (refer to procedure).
Note: Continue this procedure while the
A/C is being recovered.
- Remove the 12V battery (refer to procedure).
- Remove the 12V battery bracket beam (refer to procedure).
- Ensure that the cap on the coolant reservoir is properly
secured.
- Release the bolts (x4) that secure the coolant reservoir to the
front crossmember (torque 6 Nm). Do not remove the reservoir at this
time.
Note: At this point in the procedure, there are still 2
coolant hoses and 1 harness attached to the reservoir.
- Carefully lift up the coolant reservoir and disconnect the
coolant level sensor harness.
- Pull the reservoir forward into the underhood area.
Note: The reservoir hose is routed behind
the hose that connects to the gearbox. Note the
routing of the hoses and ensure that they are routed
correctly during reinstallation.
- Gently pull down on the 2 coolant hoses to release the clips
(x4) that secure them to the front crossmember.
- Release the clip that secures the coolant reservoir hose to the
A/C line.
- On the LH side of the 3-way fitting, clamp the coolant hose that
leads to the differential housing. Remove the hose from the front
drive unit and and plug the nipple.
Note: Disconnect the A/C machine from the vehicle at this
time.
- Move the coolant reservoir to the LH side of the vehicle and
secure it out of the working area.
Caution: The reservoir is still secured to 2
coolant hoses.
- Disconnect the compressor connector from the forward junction
box (FJB).
- Carefully cut the cable tie that secures the HV cable to the
front drive unit.
Note: Do not release the fir tree clip.
- Remove the nuts (x2) that secure the A/C suction and discharge
lines to the compressor (torque 10 Nm). Release the lines and remove
the seals. Plug the holes.
Caution: The holes must be plugged to prevent
contamination.
Caution: Remove and discard O-rings.
- Disconnect the compressor LV harness.
- Release the ground strap from the A/C compressor bracket (torque
7 Nm).
- Release the edge clip that secures the LV harnesses to the
compressor bracket.
- Release the fir tree clip that secures the LV harnesses to the
top of the front drive unit.
- Release the bolts (x3) that secure the compressor to the bracket
(torque 20 Nm).
Caution: Do not spill oil from the compressor when
removing it. The amount of oil remaining in the old
compressor needs to be measured when the new compressor is
installed.
- Remove the acoustic cover from the compressor.
Installation
Installation procedure is the reverse of removal, except for the
following:
Caution: The amount of oil in the new A/C compressor needs
to equal the amount of oil from the old one. To do this, use a
digital scale to weigh both the old and new A/C compressors.
Turn the new one upside down to drain a small amount of fluid,
then re-weigh it. Repeat this process until the new A/C
compressor weighs the same as the old one.
- Transfer the acoustic cover to the new compressor.
- Recharge the AC system.
