2008 Toyota Avalon Fuel Injector Parts Q&A

• Q: How to install the fuel injector assembly on 2008 Toyota Avalon?

  A: The first step to install the fuel injector assembly for the 2GR-FE engine includes applying spindle oil or gasoline to new O-rings before installing them to each injector then applying spindle oil or gasoline to the area where the fuel delivery pipe meets the O-ring. Insert the fuel injector into the fuel delivery pipe by turning it in both directions while maintaining the connector outside. After setting the injector in position ensure it turns smoothly before installing; otherwise replace it with a new O-ring. You will now install 6 new insulators to the intake manifold before mounting the fuel delivery pipe with its 6 fuel injectors onto the intake manifold but always avoid dropping the injectors. Apply temporary bolts to fasten the fuel delivery pipe to the intake manifold before tightening five bolts to 21 Nm (214 kgf-cm, 15 ft-lbf) for installation and then connect the six fuel injector connectors. When installing the fuel tube sub-assembly, push tube connector onto pipe until it generates the clicking sound while checking that connected parts are safe from damage and foreign objects. Additionally you should check connection stability through a pull test. Attach the No. 2 fuel pipe clamp onto position. The intake air surge tank installation should bypass bolt lubrication and instead use new gaskets and a 5 mm hexagon socket wrench to tighten 4 bolts to 18 Nm (184 kgf-cm, 13 ft-lbf) while securing the tank with 2 nuts and 2 bolts at 16 Nm (163 kgf-cm, 12 ft-lbf) and 21 Nm (214 kgf-cm, 15 ft-lbf). The procedure requires fitting the connector then applying 5.4 Nm (55 kgf-cm, 48 in-lbf) torque to the vacuum hose clamp before uniting the check valve hose to its union. Finally, install the throttle connector to the motor body assembly by conducting the following steps: clamping the vapor feed hose and connecting both water by-pass hoses to the throttle with assembly. The air cleaner cap requires installation using three clamps followed by tightening the bolt at 5.0 Nm (51 kgf-cm, 44 in-lbf) torque to connect the air flow meter connector with ventilation hose No. 1 and three vacuum hoses along with the fuel vapor feed hose No. 1. The installation order includes cowl top panel outer followed by windshield wiper motor along with link assembly followed by cowl top ventilator louver RH and finally windshield wiper arm and blade assemblies for both right-hand side and left. The coolant addition must be followed by attaching the negative cable terminal and system initialization procedures may be required after reconnecting. The installation of V-bank cover requires users to engage 3 clips starting with A and progressing to B. Users should also inspect coolant and fuel leakages.
