  Q: How to replace the A/C Compressor assembly on Scion xB?

  A:

  The w/pulley compressor assembly replacement process requires draining refrigerant from the refrigeration system through Special Service Tool: 07110-58060 (07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080). Reset refrigeration system by draining its refrigerant with Special Service Tool: 07110-58060 (07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080). After removing the engine under cover and fan and generator V belt disconnect cooler refrigerant discharge hose No.1 using a bolt and O-ring removal followed by vinyl tape-based opening sealing to stop moisture and foreign matter intrusion. Operate by unfastening the bolt from the suction hose sub-assembly while also replacing the O-ring before applying vinyl tape for closing the system openings. Disconnect the w/pulley compressor assembly connector then remove its four bolts to perform the removal. The compressor oil must be properly drained from the new w/pulley compressor assembly before installation at a volume of 60 + 15 cc (3.0 + 0.5 fl. oz.) below the present oil level of the removed compressor by using ND-OIL 8 for compressor oil. Mount the new w/pulley compressor assembly by fastening 4 bolts with 25 Nm (255 kgf.cm, 221 in.lbf) torque and then join the connector. Begin with the suction hose sub-assembly where you need to remove vinyl tape before applying compressed oil onto a fresh O-ring followed by bolt attachment. The installation of cooler refrigerant discharge hose No.1 requires removal of the vinyl tape followed by installation of oil-coated O-ring and secure bolt torqued to 9.8 Nm (100 kgf.cm, 87 in.lbf). The technician should install the fan and generator V belt afterwards adjust its position and fill the system with refrigerant through Special Service Tool: 07110-58060 (07117-58060, 07117-58070, 07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080) until the system reaches 380 plus or minus 30 g (13.9 plus or minus 1.1 oz.) before engine warming and leak inspection.

  Q: How to install the A/C Compressor on Scion xB?

  A:

  The first step to install the HVAC compressor for the 2AZ-FE involves oil level adjustment by draining appropriate oil from indicated vents after helium inert gas service valve discharge. This process should match the total oil quantity of a new compressor (90 (+15) cc (3 (+0.51) fl.oz.)) minus the amount still inside the removed compressor unit. ND-OIL8 or equivalent compressor oil must be used while taking care against overfilling because excessive oil can result in refrigeration breakdown. The compressor assembly installation requires use of a "TORX" socket wrench (E8) to torque the 2 stud bolts to 9.8 Nm (100 kgf-cm, 87 in-lbf) then completion with 2 bolts and 2 nuts torqued to 25 Nm (255 kgf-cm, 18 ft-lbf). This must be done according to the specified tightening sequence. When assembling the discharge hose between the compressor and discharge hose you must first remove the vinyl tape and apply compressor oil to both the O-ring and fitting surface before installing the O-ring onto the discharge hose while using a bolt with torque set at 9.8 Nm (100 kgf-cm, 87 in-lbf). The installation method must be performed again on the suction hose sub-assembly. The fan and generator V belt as well as rear engine under cover RH followed by No. 1 engine under cover and center transmission under cover assembly need to be installed next. End the process by charging the refrigerant system then heating the engine before conducting refrigerant leak testing.
