Compressor HVAC: Service and Repair
NOTE: Honda does not provide a procedure for replacing compressor pump shaft seal.1. If the compressor is marginally operable, run the engine at idle speed and let the air conditioning work a few minutes, then shut the engine off and disconnect the battery negative terminal.
2. Use a Refrigerant Recovery/Recycling System to recover the refrigerant from the system.
3. Remove:
- power steering mounting bolt and nut
- adjusting bolt
- adjusting bolt bracket
- power steering belt
- power steering pump
4. Remove the two cruise control actuator mounting bolts, disconnect the connector and remove the cruise control actuator.
5. Remove the alternator harness clamp and disconnect the alternator harness.
6. Remove:
- alternator mounting bolt and nut
- adjusting bolt
- adjusting bolt bracket
- compressor belt
- alternator
7. Disconnect the connectors from the condenser fan motor and noise suppressor, and remove the connector from the compressor. Remove the three mounting bolts and remove the condenser fan shroud.
CAUTION: Do not damage the radiator fins when removing the fan shroud.
8. Disconnect the suction and discharge hoses from the compressor.
CAUTION: Cap the open fittings immediately to keep moisture and dirt out of the system.
9. Remove the four compressor mounting bolts and compressor.
CAUTION: Do not damage the radiator fins when removing the fan shroud.
10. If necessary, remove the compressor bracket as shown.
11. Install in the reverse order of removal, and:
- If a new compressor is installed, calculate the amount of refrigerant oil in the A/C system by draining the oil through the suction fitting on the old compressor:
100 cc (3 1/3 fl oz) minus contents of old compressor, equals the amount of refrigerant oil to be drained from new compressor.
- Replace 0-rings with new ones at the pipe joints, and apply a thin coat of refrigerant oil before installing them.
- Do not damage the radiator fins when installing the compressor.
- Be careful to connect the alternator harness as shown.
- Adjust the belt.
- Charge the system.
- Test the performance.
