Scheme 81: LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT
  1. Before connecting recovery/recycling recharging equipment to vehicle, check recovery/recycling recharging equipment gauges. No refrigerant pressure should be displayed. If NG, recover refrigerant from equipment lines.
  2. Connect recovery/recycling recharging equipment to vehicle. Confirm refrigerant purity in supply tank using recovery/recycling recharging equipment and refrigerant identifier. If NG, refer to " «CONTAMINATED REFRIGERANT»(ref-282599-S25744937572008040500000) ".
  3. Confirm refrigerant purity in vehicle A/C system using recovery/recycling recharging equipment and refrigerant identifier. If NG, refer to " «CONTAMINATED REFRIGERANT»(ref-282599-S25744937572008040500000) ".
  4. Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure lubricant discharged into the recovery/recycling equipment.
  5. Drain the lubricant from the old (removed) compressor into a graduated container and recover the amount of lubricant drained.
  6. Drain the lubricant from the new compressor into a separate, clean container.
  7. Measure an amount of new lubricant installed equal to amount drained from old compressor. Add this lubricant to new compressor through the suction port opening.
  8. Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant to new compressor through the suction port opening.
  9. If the liquid tank also needs to be replaced, add another 5 m l (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant at this time. Do not add this 5 m l (0.2 US fl oz., 0.2 Imp fl oz.) of lubricant when replaces the compressor only.

  1. Remove condenser. Refer to " «REMOVAL AND INSTALLATION OF CONDENSER»(ref-282599-S19663640252008040500000) ".
  2. Remove refrigerant pressure sensor from condenser.
CAUTIONWhen working, be careful not to damage the condenser.

Installation is basically the reverse order of removal.

CAUTIONApply compressor oil to O-ring of refrigerant pressure sensor when installing it.
  1. Remove low-pressure pipe 2 and high-pressure pipe 3. Refer to " «REMOVAL AND INSTALLATION OF LOW-PRESSURE PIPE 2 AND HIGH-PRESSURE PIPE 3»(ref-282599-S35846778252008040500000) ". CAUTION: Cap or wrap the joint of evaporator, low-pressure pipe 2 and high-pressure pipe 3 with suitable material such as vinyl tape to avoid the entry of air.
  2. Slide evaporator, and then remove it from heater & cooling unit assembly.
  3. Remove intake sensor from evaporator, and then remove evaporator.

Installation is basically the reverse order of removal.

CAUTIONReplace O-rings of low-pressure pipe 2 and high-pressure pipe 3 with new ones, and then apply compressor oil to it when installing it. Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping straight in axial direction. Insert piping securely until a click is heard. After piping connection is completed, pull male-side piping by hand to make sure that connection does not come loose. O-rings are different from low-pressure pipe 1 (high-pressure pipe 2) and low-pressure pipe 2 (high-pressure pipe 3). Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sensor can be located in the same position. When recharging refrigerant, check for leaks. Low-pressure pipe 1 bracket mounting bolt : 5.5 N.m (0.56 kg-m, 49 in-lb)
  1. Remove evaporator. Refer to " «REMOVAL AND INSTALLATION OF EVAPORATOR»(ref-282599-S28543036892008040500000) ".
  2. Remove mounting bolts, and then remove expansion valve.
CAUTIONCap or wrap the joint of evaporator with suitable material such as vinyl tape to avoid the entry of air.

Installation is basically the reverse order of removal.

CAUTIONReplace O-rings of evaporator with new ones, and then apply compressor oil to it when installing it. O-rings are different from low-pressure pipe 1 (high-pressure pipe 2) and low-pressure pipe 2 (high-pressure pipe 3). When recharging refrigerant, check for leaks.
