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.

1. 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.

2. Recover the refrigerant with a recovery/recycling/charging station (see page 21-80).

3. Remove the drive belt (see page 4-30).

4. Remove the A/C condenser fan shroud (see page 10-13).

5. Disconnect the A/C compressor clutch connector (A).

Remove the bolts and the nut, then disconnect the suction hose (B) and the discharge hose (C) from the A/C compressor. Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.

6. Remove the mounting bolts and the A/C compressor


6. Remove the mounting bolts and the A/C compressor (A), Be careful not to damage the radiator fins when removing the compressor.

7. Install the A/C compressor in the reverse order of


7. Install the A/C compressor in the reverse order of removal, and note these items: • Inspect the A/C lines for any signs of contamination.

• If you're installing a new A/C compressor, you must calculate the amount of refrigerant oil to be removed from it (see page 21-6). A new A/C compressor comes with a full charge of oil.

• Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the correct O-rings for HFC-134a (R-134a) to avoid leakage.

• Use only PAG refrigerant oil (DENSO ND-OIL 8) for HFC-134a A/C systems.

• To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other 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; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately.

• Be careful not to damage the radiator fins when installing the A/C compressor and the A/C condenser fan shroud.

• Charge the system (see page 21-81).
