Honda Pilot: A/C Compressor Removal and Installation

Removal/Installation

NOTE:

• Do not install the A/C compressor into a system unless you are completely sure that the system is free of contamination.

  Installing the A/C compressor into a contaminated system can result in premature A/C compressor failure. Refer to the A/C System Contamination Inspection.

• If the A/C compressor is marginally operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off.

1. A/C Refrigerant - Recover

2. Alternator - Remove

3. Vehicle - Lift

4. Splash Shield - Remove

5. Right Side Front Bulkhead Brace - Remove

6. A/C Compressor - Remove

1. Disconnect the suction hose (A) and the discharge hose (B).

NOTE: Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.

2. Lower the vehicle on a lift.
3. Remove the A/C compressor (C).

NOTE: Be careful not to damage the radiator fins when removing the A/C compressor.

7. All Removed Parts - Install

1. Install the parts in the reverse order of removal, and note these items:

• Inspect the A/C lines for any signs of contamination.
• If you are installing a new A/C compressor, you must calculate the amount of refrigerant oil to be removed from it. A new A/C compressor comes with a full charge of oil.
• A new O-ring should be used at each fitting. Prior to installation, apply a thin coat of the same refrigerant oil used in the A/C compressor. Be sure to use the correct O-ring for refrigerant types to avoid leakage.
• To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other kinds of refrigerant oils.
• Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture absorption.
• Do not spill the refrigerant oil on the vehicle, because it may damage painted surfaces. If refrigerant oil contacts the paint, wash it off with water immediately.
• Be careful not to damage the radiator fins when installing the A/C compressor and the A/C condenser fan shroud.
• To avoid damage to the radiator, cover it with cardboard after removing the fan shroud.
• Charge the system with the specified amount of refrigerant.
