Tesla Model S: Compressor (Dual Motor) (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).
- Remove the wiper arms (refer to procedure).
- Remove the 12V battery bracket beam (refer to procedure).
- Ensure that the cap on the reservoir is properly secured.
- Release the 4 bolts 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.
- 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.
- Remove the LH and RH shock tower to bulkhead struts (refer to
procedure).
- Release the bolts (x2) that secure the LH fuse box to the
crossmember (torque 5 Nm).
- If the vehicle is equipped with air suspension, release the
bolts (x2) that secure the air reservoir (torque 2.5 Nm). Carefully
set the reservoir in the RH side of the underhood area.
Note: It is not necessary to disconnect the air
lines.
- Disconnect the compressor connector from the forward junction
box (FJB).
- Release the clip that secures the LH A/C line to the compressor
HV harness.
- Release the 2 nuts that secure the A/C lines to the compressor.
Plug both holes and cap both lines.
- 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.
