Compressor HVAC: Service and Repair
REMOVAL1. Remove battery ground cable.
2. Remove accessory drive belt.
3. Recover the refrigerant from the air conditioning system following the recommended service procedures. Observe all safety precautions. Refrigerant Recovery
4. Remove refrigeration line retaining bolt from A/C manifold and tube. Plug tube ports in the A/C compressor and A/C manifold and tube immediately to prevent moisture and dirt from entering the refrigerant system, and also to prevent the refrigerant oil from draining from the A/C compressor.
5. Disconnect compressor electrical connector.
6. Remove the four compressor retaining bolts from engine block.
7. Remove A/C compressor.
INSTALLATION
1. Prior to installing a replacement A/C compressor, drain the refrigerant oil from the removed compressor into a calibrated container. Rotate the shaft several revolutions to completely drain the A/C compressor.
2. Add the exact amount of clean specified refrigerant oil into the replacement A/C compressor, which is equal to the amount of refrigerant oil drained from the removed compressor. Plug compressor tube ports and install A/C compressor immediately.
3. Position the A/C compressor into position for installation.
4. Install four retaining bolts to engine block.
5. Connect compressor electrical connection.
6. Unplug compressor A/C manifold and tube and refrigerant tubes. Position A/C manifold and tube onto A/C compressor. Install and tighten retaining bolt.
7. Install accessory drive belt.
