Compressor Assembly (X22SE)
Compressor Assembly
Removal
1. Disconnect the battery ground cable.
2. Discharge and recover refrigerant
- Refer to Refrigerant Recovery in this section.
3. Disconnect magnetic clutch harness connector.
4. Remove serpentine belt.
- Move serpentine belt tensioner to loose side using wrench then remove serpentine belt.
5. Disconnect refrigerant line connector.
- When removing the line connector, the connecting part should immediately be plugged or capped to prevent foreign matter from being mixed into the line.
6. Remove compressor.
Installation
1. Install compressor.
- Tighten the compressor fixing bolts to the specified torque.
Torque: 19 N.m (14 lb ft)
2. Connect refrigerant line connector.
- Tighten the refrigerant line connector fixing bolts to the specified torque.
Torque: 15 N.m (11 lb ft)
- O-rings cannot be reused. Always replace with new ones.
- Be sure to apply new compressor oil to the O-rings when connecting refrigerant lines.
3. Install serpentine belt.
- Move serpentine belt tensioner to loose side using wrench, then install serpentine belt to normal position.
4. Connect magnetic clutch harness connector.
New Compressor Installation
The new compressor is filled with 150 cc (5.0 fl oz) of compressor oil and nitrogen gas. When mounting the compressor on the vehicle, perform the following steps:
1. Gently release nitrogen gas from the new compressor.
- Take care not to let the compressor oil flow out.
- Inspect O-rings and replace if necessary.
2. Turn the compressor several times by hand and release the compressor oil in the rotor.
3. When installing on a new system, the compressor should installed as it is. When installing on a used system, the compressor should be installed after adjusting the amount of compressor oil. (Refer to Compressor).
