Tesla Model X: Receiver Dryer and Desiccant (Remove and Replace)

Note: The desiccant bag in the receiver dryer is a serviceable item and must be replaced every 2 years, whenever the system is opened to ambient air for an extended time, or when an A/C system leak has been fixed.

Note: The dessicant is located in the LH side of the condenser.

Special tools required for this procedure:

1. Position the vehicle on a lift but do not lift it at this time.
2. Recover refrigerant from the vehicle (refer to procedure). Note: Continue this procedure while the HVAC machine is recovering the refrigerant.
3. Remove the front aero shield panel (refer to procedure).
4. Remove the 4 bolts and 6 clips that secure the lower front fascia to the front fascia, and then remove the lower front fascia.

   

5. Use a Torx T50 to remove the cover from the LH side of the condenser (torque 4 Nm).

    

6. Remove the snap ring from the condenser.

    

7. Use the small slide hammer to pull out the inner plug. Discard the inner plug.

   Warning: To avoid personal injury, eye protection must be worn when performing this operation.

   Warning: HFO-R1234yf and R134a are considered hazardous liquids and if handled incorrectly can cause serious injury. Suitable protective clothing, consisting of face and eye protection, heat-proof gloves, rubber boots and apron or waterproof overalls must be worn when carrying out operations on the air conditioning system.

    

8. Remove the desiccant bag.

    

Installation procedure is the reverse of removal, except for the following:

Caution: Install a new desiccant bag and a new plug immediately to prevent ingress of dirt and moisture.
