Tesla Model 3: Evaporator (Remove and Replace)

Evaporator- Remove

Remove

1. Remove the HVAC assembly. See HVAC Assembly (Remove and Replace).
2. Put the HVAC assembly on a working surface. Make sure that the HVAC assembly is on its side with the HVAC inlet facing up.
3. Remove the TXV O-ring seals (x2) from the HVAC assembly.

4. Release the clips that attach the PTC electrical harness to the HVAC assembly, and the remove the PTC electrical harness from the HVAC assembly.

5. Remove the screws that attach the PTC to the HVAC assembly, and then pull out the PTC heater from the HVAC assembly.

6. Remove the screws that attach the lower evaporator cover to the HVAC assembly, and then remove the lower evaporator cover from the HVAC assembly.

7. Remove the sealing ring from the HVAC assembly.

8. Remove the screws that attach the HVAC inlet to the HVAC assembly.

9. Disconnect the electrical connector from the HVAC inlet actuator.

10. Lift the side that covers the evaporator pipes, rotate the HVAC inlet out of the retaining slots on the HVAC assembly, and then remove the HVAC inlet from the HVAC assembly.

11. Remove the screws (x3) that attach the upper evaporator cover to the HVAC assembly.

12. Remove the upper evaporator cover from the HVAC assembly by lifting the cover off of the HVAC assembly.

13. Slide the evaporator out of the HVAC assembly, and then remove the evaporator from the HVAC assembly.

Evaporator- Install

Install

1. Install the new evaporator into the HVAC assembly.

Caution:

Do not damage the temperature sensor when installing the new evaporator into the HVAC assembly.

Note: Make sure that the evaporator slides into the HVAC assembly with the correct channels until the evaporator stops. The evaporator pipes must line up with the slots for the evaporator covers on the HVAC assembly.

2. Install the screws that attach the evaporator upper cover to the HVAC assembly. Torque 1.4 Nm

3. Install the HVAC inlet onto the HVAC assembly.

Note: Insert the 2 tabs into the slots on the HVAC assembly at an angle, and then set flat onto the HVAC assembly.

4. Install the screws that attach the HVAC inlet to the HVAC assembly. Torque 1.4 Nm

5. Connect the HVAC inlet actuator electrical connector.

6. Install the seal onto the HVAC assembly around the evaporator pipes.

Note: The seal should be flushed against the HVAC assembly, even though the evaporator pipes are at an angle.

7. Install the screws that attach the lower evaporator cover onto the HVAC assembly. Torque 1.4 Nm

Note: Make sure that the dowels on the lower evaporator cover engage the HVAC assembly.

8. Install the PTC heater into the HVAC assembly.

Note: The PTC heater will slide into the HVAC assembly one way only.

9. Install the screws that attach the PTC heater to the HVAC assembly. Torque 2.9 Nm

10. Install the clips that attach PTC heather electrical harness onto the HVAC assembly.
11. Install new O-ring seals onto the HVAC assembly.
12. Install the HVAC assembly in the vehicle. See HVAC Assembly (Remove and Replace).
