Q: How to remove the A/C Compressor and pulley on Toyota Camry?
A: The first step for removing the air conditioning compressor and pulley from 2AZ-FE engines requires extracting refrigerant from the refrigeration system. You must disconnect the refrigerant lines but should wait for 90 seconds past when you disconnect the cable to stop Air Bag activation. The first step requires draining engine coolant followed by front right wheel removal together with engine under cover right and front fender apron seal right. The following steps include generator assembly removal after V-ribbed belt detachment. Use pliers to detach radiator hose outlet by sliding off the clip claws. Disconnect the piping clamp of the No. 1 cooler refrigerant discharge hose and suction hose using proper tools. The technician must disconnect the No. 1 cooler refrigerant discharge hose by removing both a bolt and an O-ring before sealing the openings with vinyl tape to block moisture and foreign matter. Repetitive steps should also be carried out on the No. 1 cooler refrigerant suction hose. The last step includes unfastening both connector and four bolts to separate engine wire harness bracket with compressor and pulley.
Q: How to replace the A/C Compressor and its magnetic clutch in a refrigeration system on Toyota Corolla?
A: The first step to replace the compressor and magnetic clutch requires exhausting refrigerant from the refrigeration system by using Special Service Tool: 07110-58060 (07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080). The procedure for removing Cleaner cooler refrigerant suction hose No.1 requires users to remove its bolt and o-ring and cover both openings with vinyl tape to stop moisture and foreign matter from entering. The second task involves removing the discharge hose sub-assy through bolt removal and O-ring extraction and sealing the exposed ends using vinyl tape. The procedure starts by removing the engine under cover RH and fan and generator V belt then proceeding to disconnect compressor and magnetic clutch connectors while removing three bolts. You should place the compressor in a vise clamp before removing the bolt with vise pliers while taking off the hub along with the washer from the magnet clutch assembly. The snap ring expander lets you extract both the snap ring and rotor before you uninstall the connector and remover the snap ring and starter. Move on to uninstall the components of the cooler compressor. The installation process for the magnet clutch assembly starts with part matching according to the visuals followed by starter installation and utilization of a snap ring expander to put in the new snap ring with the chamfered side facing upwards. After installing the screw and connector, add the rotor together with another new snap ring that has its chamfered side facing upward and then attach the washer and hub maintaining the original magnet clutch washer arrangement. Use a 18 Nm (183 kgf.cm, 13 ft.lbf) torque value to fasten the hub by bolt. An inspection of the magnetic clutch requires a dial indicator during which you should connect the battery leads to the magnet clutch connector while measuring the clearance within 0.35 - 0.60 mm (0.013 - 0.023 in.) range. Use three maximum number of magnet clutch washers to reposition the clearance when it exists the recommended range. To replace the compressor and magnetic clutch drain the necessary oil amount by subtracting the remaining oil amount from the new unit oil capacity which equals 120 + 15 cc (4.0 + 0.5 fl.oz.). Use ND-OIL8 for compressor oil. You should torque the compressor and magnetic clutch with three bolts to 29 Nm (295 kgf.cm, 21 ft.lbf) after installation then connect the connector. The discharge hose sub-assy installation requires compressor oil application onto the new O-ring and fitting surface before torquing the bolt to 9.8 Nm (100 kgf.cm, 87 in.lbf). Rephrase and tighten the bolt connecting cooler refrigerant suction hose No.1 with 9.8 Nm (100 kgf.cm, 87 in.lbf) after applying compressor oil to its new O-ring and fitting surface. Finish the charging of refrigerant by using Special Service Tools: 07117-48130, 07117-48140, 07110-58060 (07117-58060, 07117-58070, 07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080) and 490 plus or minus 30 g (17.28 plus or minus 1.06 oz.) of specified amount while engine heating and checking for refrigerant leaks.
Q: How to remove the A/C Compressor and pulley on Toyota RAV4?
A: 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.
