• Q: How to install the A/C Compressor on 2008 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.
