A/C COMPRESSOR REMOVAL/INSTALLATION [LF, L3]
1. Disconnect the negative battery cable.
2. Discharge the refrigerant. (See REFRIGERANT CHARGING.)
3. Remove the splash shield.
4. Remove the A/C drive belt.
5. Detach the two wiring harness clamps.
6. Disconnect the magnetic clutch connector.
7. Remove the A/C compressor protector.
8. Disconnect the cooler hose (LO) and cooler hose (HI). Do not allow remaining compressor oil in the refrigerant line to spill.

CAUTION: If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and abnormal noise or other malfunction could occur. Always plug open fittings immediately after removing any refrigeration cycle parts.

9. Remove the compressor protector.

10. Remove in the order indicated in the table. Do not allow remaining compressor oil in the A/C compressor to spill.

CAUTION: If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and abnormal noise or other malfunction could occur. Always plug open fittings immediately after removing any refrigeration cycle parts.

11. Install in the reverse order of removal.
12. Perform the refrigerant system performance test. (See REFRIGERANT SYSTEM PERFORMANCE TEST. See: Heating and Air Conditioning > Component Tests and General Diagnostics > Refrigerant System Performance Test)

A/C Compressor Installation Note

CAUTION: Due to the high moisture-absorption characteristics of the compressor oil, it may absorb moisture if left over a long period of time thereby negatively affecting A/C operation. Drain the compressor oil and refill within 10 min. of each other.

1. Rotate new A/C compressor shaft six to eight revolutions while collecting refrigerant oil in a clean measuring device. Use this refrigerant oil to refill new compressor. Do not allow refrigerant oil to become contaminated.
2. Rotate old A/C compressor shaft six to eight revolutions while collecting refrigerant oil in a separate, clean measuring device.
3. Compare those oil amounts. The amount of the oil drained from the new A/C compressor should be greater than the old one.

4. Pour the same amount oil of drained from the old A/C compressor back into the new A/C compressor.
