• Q: How to replace the Fuel Injector Assembly on 2003 Toyota Camry?

  A: Before replacing the Fuel Injector Assy (2AZ-FE) you must establish methods to stop gasoline leakage. Start by removing the air cleaner cap and air cleaner hose and proceeding to uninstall the engine cover sub-assy No. 1. Disconnect all fuel tube sub-assy components before you remove the fuel delivery pipe together with its injector but keep all items secure as you work to prevent dropping the injectors. Start the procedure by removing the ventilation hose No. 2 before disconnecting the four injector connectors from each injector. The delivery pipe removal process begins by unfastening the two clamps then dissembling the wire harness before Moving on to disconnect the two bolts securing the delivery pipe and installers. The final removal items are the two head spacers. A technician should pull the four injectors from the delivery pipe to remove the fuel injector assembly. New insulators need to be installed followed by spreading spindle oil or gasoline on fresh O-rings before fitting them onto each injector while applying a light coat of spindle oil or gasoline at the delivery pipe O-ring interface. When installing the four injectors into the delivery pipe by rotating them clockwise and counterclockwise seek to avoid twisting the O-ring while verifying smooth rotation of each injector; replace the injector if it fails to rotate properly. Position the injector connector downward. The procedure for installing the delivery pipe with injectors requires users to install first two spacers onto the cylinder head followed by placing the delivery pipe with four injectors into position before using temporary bolts to secure the pipe on the head. A proper inspection of the injector movement should take place before proceeding; the O-ring requires replacement if injector smoothness is not detected. The two bolts securing the delivery pipe to the cylinder head must be tightened to 20 N.m (204 kgf.cm, 15 ft.lbf) while keeping the injector connector in an outward position. Examine the system for fuel leaks as the last check.
