Tesla Model 3: Compressor- Install
- Remove the port plugs and port nuts from the replacement compressor.
- Use the digital scale to weigh the replacement compressor and record its
weight.
- Subtract the weight of the removed compressor from the weight of the
replacement compressor. The difference is the weight of oil to be removed
from the replacement compressor.
- Turn the replacement compressor upside down to drain a small amount of
oil from the suction (large) port into a clean, dry collection container.
Note: If necessary, the collected oil can be reused later
for A/C system recharge.
- Repeat step
2 through step
4 until the weight of the replacement compressor is the same as the
removed compressor.
- Install the acoustic cover over the compressor, and then fasten the
clips that attach the cover over the compressor.
- Install the intermediate bracket onto the compressor, and then install
the bolts that attach the bracket to the compressor.
Torque 10 Nm
- Fasten the clip that attaches the compressor HV electrical harness to
the intermediate bracket.
- Install the compressor under the shock tower brace, and then install the
bolts that attach the compressor to the shock tower brace.
Torque 10 Nm
- Move the compressor HV electrical harness behind the shock tower brace.
- Fasten the clip that attaches the compressor HV electrical harness to
the body.
- Install a new o-ring onto the suction/liquid line, insert the line into
the compressor, and then install the nut that attaches the line to the
compressor.
Torque 22 Nm
- Install a new o-ring onto the discharge line, insert the line into the
compressor, and then install the nut that attaches the line to the
compressor.
Torque 22 Nm
- Fasten the clip that attaches the suction/liquid lines to the
superbottle.
- Connect the electrical harness to the powertrain coolant pump connector.
- Fasten the clip that attaches the electrical harness to the suction
liquid line.
- Install new o-rings onto the suction/liquid line fitting, install the
fitting into the chiller and EXV assembly, and then install the bolt that
attaches the fitting to the chiller and EXV assembly.
Torque 5.5 Nm
- Connect the electrical harness to the low pressure transducer connector.
- Install the suction/liquid line bracket onto the shock tower brace, and
then install the bolt that attaches the bracket to the brace.
Torque 5.5 Nm
- Fasten the clips that attach the low voltage electrical harness to the
compressor and compressor bracket.
- Install the bolt that attaches the ground harness to the compressor.
Torque 6 Nm
- Connect the low voltage electrical harness to the compressor connector.
- Raise the vehicle.
- Connect the electrical harness to the high pressure transducer connector.
- Fasten the clips that attach the compressor HV electrical harness to the
bulkhead.
- Connect the compressor HV electrical connector to the HV electrical
harness.
- Install the front aero shield. See
Panel - Aero Shield - Front (Remove and Replace).
- Connect the red high pressure hose to the vehicle's high pressure port,
and the blue low pressure hose to the vehicle's low pressure port.
- Start the A/C vacuum and leak test, and continue with this procedure
while the tests are running.
- Perform the penthouse air leak test. See
Penthouse Air Leak Test.
- Connect the charge port electrical harness to the penthouse DC input
connector. Close the locking handle and slide the security tab to the lock
position.
- Install the clip that attaches the charge port electrical harness to the
vehicle.
- Position the charge port to HV battery harness bracket on the body, and
then install the bolts that attach the bracket to the body.
Torque 10 Nm
- Install the clips that attach the low voltage electrical harness to the
charge port to HV battery harness bracket at the penthouse.
- Install the LH rear sill panel trim. See
Trim - Sill Panel - Rear - LH (Remove and Replace).
- Install the LH 2nd row seat side bolster. See
Bolster - Side - Seat - 2nd Row - LH (Remove and Replace).
- Install the penthouse HV cap. See
Cap - Penthouse HV (Remove and Replace).
- Connect 12V power. See
12V Power (Disconnect and Connect).
Note: Do not install the rear apron at this time.
- When the A/C vacuum and leak test is complete, recharge the refrigerant.
See
A/C Refrigerant (Recovery and Recharge).
- Connect a laptop with Toolbox to the vehicle.
- Update the vehicle firmware.
- After the A/C refrigerant recharge has fully completed, verify the
operation of the A/C system.
- Connect a charge cable to the vehicle, and then use Toolbox to run the
"TEST-SELF_VCFRONT_X_THERMAL-PERFORMANCE" test to verify the replacement
compressor operation.
- Disconnect the charge cable and laptop from the vehicle.
- Install the outer HVAC plenum duct. See
Duct - HVAC Plenum - Outer (Remove and Replace).
- Install the underhood storage unit. See
Underhood Storage Unit (Remove and Replace).
