Compressor Assembly

The first step to remove the 2AZ-FE engine air conditioning compressor and pulley demands a discharge of refrigerant substance from the refrigeration system. Before putting away the cable from the negative battery terminal maintain a minimum wait time of 90 seconds to stop Air Bag and seat belt pretensioner activation. Separate the No. 1 cooler refrigerant suction hose by unfastening its bolt and O-ring while minimizing foreign material ingress by covering exposed areas with vinyl tape. The procedure is repeated for removing the No. 1 cooler refrigerant discharge hose. Remove the engine under cover for No. 1 before taking out the V belt in sections from the fan and generator. You must disconnect the cooler compressor connector and separate the 4 bolts when there is no stud bolt but if there is you should detach the 3 bolts and nut to remove the cooler compressor.

The air conditioning compressor and pulley installation requires adjusting the compressor oil through refrigerator gas service valve discharge and manual oil drainage from new components that totals 130 + 15 cc (4.6 + 0.51 fl.oz.) and includes remaining oil from previous components. The procedure of checking the compressor oil requires safe handling of coolers during removal and installation because both excessive or insufficient oil will affect the refrigerant's operation. The oil system requires ND-OIL 8 as its specific product or any approved substitute as compressor fluid. To install the cooler compressor assembly either without or with a stud bolt you should tighten four bolts to 24.5 Nm (250 kgf-cm, 18 ft-lbf) or use three bolts with a nut following the same torque setting. Installation of the No. 1 discharge hose starts by removing vinyl tape, applying compressor oil to both the fitting surface and new ring before installation with a bolt tightened to 9.8 Nm (100 kgf-cm, 7 ft-lbf). Repetition of this installation method should occur for the No. 1 cooler refrigerant suction hose. The procedure requires installation of the fan and generator V belt alongside the No. 1 engine under cover and connecting the cable to the negative battery terminal. The last step includes charging the refrigerant while allowing the engine to warm during an examination for leaking refrigerant.

Install it with the appropriate bolts, tightening them to a torque of 24.5 N.m (250 kgf.cm, 18 ft.lbf) in the specified order, and reconnect the connector.
