Rear A/C Unit Installation Note

  1. When installing a new rear A/C unit or rear evaporator, add a supplemental amount of DENSO OIL 8 compressor oil into the refrigerant cycle. Supplemental amount (approx. quantity) 40 ml {40 cc, 1.4 fl oz}

Scheme 21

Scheme 21: REAR A/C UNIT DISASSEMBLY/ASSEMBLY
  1. Disassemble in the order indicated in the table.
  2. Assemble in the reverse order of disassembly.

A/C Compressor Installation Note

CAUTIONDue 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.

Scheme 22

Scheme 22
  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. A/C compressor oil type DENSO OIL 8 A/C compressor oil sealed volume (approx. quantity) 160 ml {160 cc, 5.41 fl oz}

Scheme 23: CONDENSER REMOVAL/INSTALLATION
  1. Disconnect the negative battery cable.
  2. Discharge the refrigerant. (See REFRIGERANT CHARGING article.)
  3. Drain the engine coolant. (See «ENGINE COOLANT REPLACEMENT [MZI-3.7]»(ref-663017-S17886152422014101600000) article.)
  4. Remove the air cleaner and fresh air duct component. (See «INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7]»(ref-663036-S20639303202014101600000) article.)
  5. Remove the cooling fan component. (See «FAN MOTOR INSPECTION [MZI-3.7]»(ref-663017-S10011863382014101600000) article.)
  6. Disconnect the ATF oil cooler hose from the radiator.
  7. Remove the radiator. (See «RADIATOR REMOVAL/INSTALLATION [MZI-3.7]»(ref-663017-S10301572142014101600000) article.)
  8. Remove the nut and disconnect front cooler pipes No. 3 and No. 4. (See «REFRIGERANT LINE REMOVAL/INSTALLATION»(ref-663011-S25515470512014101600000) .)
  9. Remove the front cooler pipe No. 3 bracket. (See «REFRIGERANT LINE REMOVAL/INSTALLATION»(ref-663011-S25515470512014101600000) .)
  10. Remove the bolts and two condenser brackets.
  11. Remove in the order indicated in the table. 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.
