• Q: How to replace the fuel injector on 2006 Toyota Avalon?

  A: The first step for fuel injector replacement includes preventing fuel leakage while disconnecting the negative battery terminal cable. The technician will drain engine coolant before taking out the FR wiper arm and blade assembly LH and RH followed by cowl top ventilator louver RH and windshield wiper motor and link assembly and cowl top panel outer. The V-bank cover sub-assembly comes out by first taking off air cleaner cap with air cleaner hose which requires disconnecting all vacuum hoses and ventilation hose No.1 and air flow meter connector, fuel vapor feed hose No.1 and untightening hose clamp bolt then removing all 3 clamps. Start by detaching all the components of the intake air surge tank through the process of removing 2 water bypass hoses and the vapor feed hose and throttle w/ motor body assembly connector and clamp along with ventilation hose No.2 and union to check valve hose and next dissassembling 4 bolts using a 5 mm socket hexagon wrench then continuing with 2 nuts 2 bolts and gasket removal. Eliminate the fuel tube sub-assembly through the removal of fuel pipe clamp No.2 followed by careful extraction of the fuel pipe but maintain the connector free from dirt contamination. Following connection removal of the 6 fuel injector connectors the technician will detach the fuel delivery pipe which contains the 6 fuel injectors, enabled by removing 5 bolts before removing 6 insulators from the intake manifold to separate the fuel injectors. The first step for injector installation includes applying a small amount of spindle oil or gasoline to new O-rings followed by their placement onto each injector where the fuel injector connector must point to the exterior. The first step requires installation of 6 new insulators to the intake manifold followed by placing the fuel delivery pipe with 6 fuel injectors onto the intake manifold along with temporary bolt installation. Install the 6 fuel injector cables and fasten all 5 bolts with torque at 21 N.m (214 kgf.cm, 15 ft.lbf). Install the fuel pipe clamp No.2 after pushing the tube connector until it establishes a click. A new surge tank gasket should be installed for securing with 4 bolts torqued to 18 N.m which equals 184 kgf.cm or 13 ft.lbf while 2 nuts and 2 bolts need to be installed at specified torques. Proceed with reinstallation of all intake air surge tank and air cleaner cap linked hoses together along with clamps making sure each junction is secure. The technician will first reinstall cowl top panel outer followed by windshield wiper motor & link assembly and cowl top ventilator louver RH along with FR wiper arm & blade assemblies. After filling engine coolant, reconnect the negative battery terminal to check for leaks before engaging the 3 clips to properly install the V-bank cover sub-assembly. The systems need initialization following disconnection of the battery terminal.
