• Q: How to replace the A/C Compressor Assy on 2004 Toyota Prius?

  A: The repair of Electric Inverter Compressor Assy requires first removing Rear Floor Board No.2 together with Deck Floor Box Rear and Rear Floor Board No.3. Remove the service plug grip after disconnecting the battery negative terminal. The process of removing refrigerant from the refrigeration system requires Special Service Tool: 07110-58060 (07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, and 07117-88080). Disconnect the discharge hose sub-assy by removing its bolt along with O-ring and then secure openings with vinyl tape to block moisture and foreign matter. Seal the openings of the suction hose sub-assy before removing the Electric Inverter Compressor Assy by releasing the green-lock and disconnecting the connector. You must also remove the three clamps and bolts. Check the compressor oil while properly draining the necessary quantity from the new compressor unit before assembly under safe oil level and types conditions. Use two bolts to temporarily secure the Electric Inverter Compressor Assy while fully tightening both bolts to 25 Nm (255 kgf.cm, 18 ft.lbf) according to the specified order. The wire harness requires connection after proper adherence to the green lock location. Mount the suction hose sub-assy after installing its new O-ring and adding ND-OIL 11 or equivalent compressor oil while tightening the bolt to 9.8 Nm (100 kgf.cm, 87 in.lbf). Complete this procedure twice on the discharge hose sub-assy. Reinstall the service plug grip before you reconnect the battery negative terminal and place the rear floor components in their correct positions. Charging of refrigerant through Special Service Tool (07110-58060 and others) must reach 450 plus or minus 30 g (15.87 plus or minus 1.05 oz.) before warming up the compressor to check for any refrigerant leakage.
