Receiver Dryer: Service and Repair

-
RECEIVER DRIER REMOVAL/INSTALLATION - HYBRID









CAUTION:Electric Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Electric Compressor Oil to the hybrid vehicle refrigerant system will damage the electric Air Conditioning (A/C) compressor and contaminate the refrigerant system. See Air Conditioning (A/C) System Evacuation And Charging.
NOTE:Installation of a new receiver/drier is not required when repairing the A/C system, except when there is physical evidence of contamination from a failed A/C compressor or damage to the receiver/drier. Damage to the receiver/drier includes leaks, physical damage to the receiver/drier shell or desiccant, or moisture contamination. Moisture contamination results only from a complete loss of refrigerant, and equalization of the refrigerant system pressure with atmospheric pressure for a period longer than one hour. If even a slight amount of positive refrigerant pressure is present in the refrigerant system before repairs are carried out, a new receiver/drier should not be installed.
NOTE:The receiver/drier fitting studs can be removed and installed separately from the receiver/drier and are available as service parts. If only the fitting studs are damaged, it is not necessary to install a new receiver/drier.
1. Recover the refrigerant. See Air Conditioning (A/C) System Discharging And Recovery.

2. Remove the evaporator inlet line bracket nut.

- To install, tighten to 7 Nm {0.7 kgf-m, 62 in-lbf}.

3. Disconnect the A/C pressure transducer electrical connector.

4. Remove the receiver/drier inlet fitting nut and disconnect the fitting.

- Discard the O-ring seal and gasket seal.
- To install, tighten to 15 Nm {1.5 kgf-m, 133 in-lbf}.

5. Remove the receiver/drier outlet fitting nut and disconnect the fitting.

- Discard the O-ring seal and gasket seal.
- To install, tighten to 15 Nm {1.5 kgf-m, 133 in-lbf}.

6. Remove the 2 receiver/drier nuts.

- To install, tighten to 7 Nm {0.7 kgf-m, 62 in-lbf}.

CAUTION:Electric Compressor Oil only must be used as a refrigerant system lubricant for hybrid vehicles. Addition of any oil other than Electric Compressor Oil to the hybrid vehicle refrigerant system will damage the electric Air Conditioning (A/C) compressor and contaminate the refrigerant system. See Air Conditioning (A/C) System Evacuation And Charging.
7. To install, reverse the removal procedure.

- Install new gasket seals and O-ring seals.
- Add the correct amount of clean electric A/C compressor oil to the refrigerant system. See Air Conditioning (A/C) System Evacuation And Charging.

8. Evacuate, leak test and charge the refrigerant system. See Air Conditioning (A/C) System Evacuation And Charging.
