A/C Compressor Installation Note

Scheme 15

1. Rotate new A/C compressor shaft six to eight revolutions while draining new 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 draining old 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. A/C compressor oil type DH-PR A/C compressor oil sealed volume (approx. quantity) 130 ml {130 cc, 4.39 fl oz}

Scheme 16

1. Remove the battery cover.
2. Disconnect the negative battery cable. (See «BATTERY REMOVAL/INSTALLATION [LF]»(ref-244448-S25513985422006092400000).)
3. Discharge the refrigerant from the system. (See «REFRIGERANT CHARGING»(ref-244471-S09026287512006092400000).)
4. Remove the splash shields.
5. Remove the under cover.
6. Remove the cooling pipe installation bolts.
7. Do not allow remaining compressor oil in the condenser and pipes to spill, and remove in the order indicated in (Scheme 16). 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.
8. Install in the reverse order of removal.
9. Perform the refrigerant system performance test. (See «REFRIGERANT SYSTEM PERFORMANCE TEST»(ref-244471-S34192899222006092400000).)

Condenser Installation Note

1. When replacing the new condenser, add compressor oil to the refrigeration cycle. Supplemental amount (approx. quantity) 20 ml {20 cc, 0.7 fl oz}
