  Q: How to remove the A/C Compressor on Toyota Matrix?

  A:

  A proper HVAC compressor removal for 2AZ-FE engines starts by recovering refrigerant from the refrigeration system. The first step requires removal of both the right-hand side engine under cover along with the V-ribbed belt. Remove the bolt to disconnect the suction hose sub-assembly from the compressor assembly with pulley before taking out the O-ring from the No.1 cooler refrigerant suction hose. Properly tape all opened sections with vinyl to block entry of moisture and foreign matter. Disconnection of the discharge hose sub-assembly starts with bolthook removal and pulley separation from the compressor assembly after which the O-ring from the discharge hose sub-assembly needs removal before opening sealing. To remove the compressor assembly with pulley start by disconnecting the connector and afterward removing the bolts and nuts followed by using a "TORX" socket wrench (E8) to detach the stud bolts together with the compressor assembly.

  Q: How to install the A/C Compressor on Toyota Matrix?

  A:

  The installation of an HVAC compressor for the 2AZ-FE requires first step-by-step reduction of inert gas (helium) from the service valve and then draining the correct amount of oil from the specified vents before reinstalling the drain bolt and washer. The total oil capacity for the new compressor ranges between 90 + 15 cc (3.04 + 0.51 fl.oz.) however the needed oil removal amount is determined by subtracting the current oil volume inside the original compressor. The system will fail if too much oil enters the refrigeration system so ND-OIL 8 or an equivalent compressor oil should be used carefully. Install the compressor assembly with pulley by using a "TORX" socket wrench (E8) then attach it with 2 stud bolts at 9.8 Nm (100 kgf-cm, 87 in-lbf) torque followed by attaching 2 bolts and 2 nuts at 25 Nm (255 kgf-cm, 18 ft-lbf) then tighten in the specified order. First remove the vinyl tape from the discharge hose sub-assembly then apply compressor oil to a new O-ring and the fit surface before installing the O-ring and fastening it with a bolt at 9.8 Nm (100 kgf-cm, 87 in-lbf). Perform this installation method again when connecting the suction hose sub-assembly. Complete the procedure by installing the V-ribbed belt before checking it and attaching the engine under cover RH and filling the system with refrigerant and allowing the engine to warm up and performing a refrigerant leak inspection.
