9. Remove bolts B.
10. Remove the A/C compressor. Do not allow compressor oil to spill..
11. Install in the reverse order of removal.
12. Perform the 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 the new A/C compressor shaft six to eight revolutions while pouring refrigerant oil in a clean measuring container. 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 pouring refrigerant oil in a separate, clean measuring container.
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 drained from the old A/C compressor back into the new A/C compressor.
