Compressor Assembly

You should begin by adjusting the compressor oil through gentle helium inert gas valve drain followed by venting the correct amount of oil from specified ports until the oil difference equals the 90 (+15) cc (3 (+0.51) fl.oz.) contained in the new unit and the leftover oil in the old compressor. A compressor oil of Equivalent to ND-OIL8 is recommended while operators need to watch for excessive oil buildup that could result in refrigeration system failure. Connect the compressor assembly with a "TORX" socket wrench (E8) using 2 stud bolts that need tightening to 9.8 Nm (100 kgf-cm, 87 in-lbf). Finish by attaching 2 bolts and 2 nuts with a torque of 25 Nm (255 kgf-cm, 18 ft-lbf) following the provided sequence. The discharge hose sub-assembly installation requires users to remove the vinyl tape followed by applying compressor oil to the fitting surface and new O-ring then securing the O-ring and fitting the hose to the compressor with a bolt tightened to 9.8 Nm (100 kgf-cm, 87 in-lbf). The installation process for the suction hose sub-assembly requires compressor oil on a new O-ring before its placement. The maintenance process requires installation of components that include the fan V belt together with the generator V belt and the rear engine under cover RH followed by the No. 1 engine under cover and ending with the center transmission under cover assembly. Finish the process by loading refrigerant into the system followed by engine heating and leak inspection procedures.

The first task before removing the 2AZ-FE engine HVAC compressor requires performing a refrigerant recovery process from the refrigeration system. Start by taking off the rear engine under cover RH and the No. 1 engine under cover from the vehicle. Next disconnect the fan and generator V belt. The suction hose sub-assembly requires removing its bolt along with its O-ring before securing the openings with vinyl tape as moisture and foreign material prevention. The discharge hose sub-assembly requires removal of its bolt and O-ring followed by opening closure with vinyl tape across both sections. The compressor assembly removal process requires disconnecting the connector and taking out the two bolts and two nuts while using a "TORX" socket wrench (E8) to extract the two stud bolts and the compressor.

Disconnect the connector, remove the 2 bolts and 2 nuts, and use a "TORX" socket wrench (E8) to remove the 2 stud bolts and the compressor.

Adjust the compressor oil level by discharging inert gas (helium) from the service valve and draining the appropriate amount of oil from the indicated vents.

Use ND-OIL8 or an equivalent for compressor oil.

Use ND-OIL 8 or equivalent for compressor oil.

Remove the engine under cover on the right-hand side and the V-ribbed belt.
