  Q: How to remove and install the A/C Compressor on Scion tC?

  A: The first step for removing the HVAC compressor requires refrigerant discharge from the refrigeration system followed by waiting 90 seconds to disconnect the negative battery terminal cable and disable Air Bags and pretensioners. You must disconnect the No.1 cooler refrigerant suction hose while removing its bolt and O-ring and use vinyl tape to seal the openings to keep moisture along with foreign matter from entering. The same procedure should be used to disconnect the No.1 cooler refrigerant discharge hose. The first step involves removing the engine under cover RH, the fan as well as generator V belt followed by disconnecting the connector and removing the four bolts from the cooler compressor assembly. The cooler compressor assembly requires four bolts for installation at 25 N.m torque strength (255 kgf.cm, 18 ft.lbf). Reconnect the connector afterwards. For installing the No.1 cooler refrigerant discharge hose first remove its vinyl tape then apply compressor oil (ND-OIL 8 or equivalent) to a new O-ring and the fitting surface before installing the O-ring and securing the hose with a bolt torqued to 9.8 N.m (100 kgf.cm, 7 ft.lbf). You should follow the same installation sequence for the No.1 cooler refrigerant suction hose. Finally reconnect the cable to the negative battery terminal while you reattach the generator V belt and fan as well as the engine under cover RH. Multiple systems need initialization following a battery reconnection procedure. The refrigerant charging process requires engine warming and full refrigerant leak inspection.
