The installation of the 2AZ-FE engine's air conditioning compressor and pulley requires helium discharge from the service valve to adjust oil level followed by draining specified oil amounts from designated vents while using ND-OIL 8 or equivalent as the compressor oil. The new compressor along with magnetic clutch demands 160 + 15 cc (5.4 + 0.51 fl. oz.) of standard oil but you need to calculate any leftover oil from components for proper refrigeration performance. You must install the compressor and pulley after fitting the engine wire harness bracket while tightening four bolts to 25 Nm (255 kgf-cm, 18 ft-lbf) torque values that use the detailed tightening procedure. Install the No. 1 cooler refrigerant suction hose by removing the vinyl tape then applying compressor oil to a new O-ring and fitting surface before fastening it with a bolt at 9.8 Nm (100 kgf-cm, 87 in-lbf). Applicatoin of correct oil followed by the specified torque must be done for both the No. 1 cooler refrigerant discharge hoses. The piping clamp should be installed to both hoses before installing the generator assembly and V-ribbed belt and front fender apron seal RH and finally attaching the radiator hose outlet equipped with its clip. The battery negative terminal connection process must be finished before engine coolant addition and leak inspection takes place to avoid overheating the compressor when charging with refrigerant with the A/C system off. Installing the engine under cover RH and front wheel RH completes the procedure by following refrigerant charging then warming the engine for leak detection.
