2004 Toyota Celica Parts Questions & Experts Answers

• Q: How to service and repair the A/C Clutch on 2004 Toyota Celica?

  A: The first step to maintain the compressor clutch requires allowing the engine to operate at idle speed with the A/C on for ten minutes followed by stopping the engine and removing the negative cable from the battery terminal. Remove the drive belt from the system after discharging the refrigeration system refrigerant. The service requires removal of the cruise control actuator during the 1ZZ-FE engine work and the air pump assembly removal during the 2ZZ-GE engine tasks. Removing the 2 bolts from discharge and suction hoses enables capping the open fittings to stop moisture or dirt from entering the system. Uninstalling the compressor requires disconnecting its connector and wire harness clamp together with removing 3 bolts. Follow these instructions to install the compressor: first fasten it with the 3 bolts at 25 N.m (250 kgf.cm, 18 ft.lbf) torque setting then restore the connector linkage. Set up the discharge and suction hoses through the compressor oil lubricating process of 2 new O-rings which should be installed to their hose positions before tightening 2 corresponding bolts to 10 N.m (100 kgf.cm, 7 ft.lbf torque). Cruise control actuators should be installed with the 1ZZ-FE engine but air pump assemblies need installation with the 2ZZ-GE engine. Reinstall and check the drive belt after which you should connect the negative (-) terminal cable to the battery. Evacuate the refrigeration system followed by the installation of specified refrigerant amount at 430 plus or minus 30 g (15.17 plus or minus 1.06 oz.). An inspection of refrigerator leakage with a gas leak detector should be performed and a torque check for loose fitting joints should be conducted when any leakages are detected as part of the A/C inspection process.
