OEM 2009 Toyota Avalon Fuel Injector

2009 Toyota Avalon Parts Questions & Experts Answers

• Q: How to install the fuel injector assembly and related components on 2009 Toyota Avalon?

  A: Start by applying a light coat of spindle oil or gasoline to the new O-rings before installing one to each injector. At the same time use a light coat of spindle oil or gasoline to apply to the O-ring contact point between the fuel delivery pipe. Place the fuel injector inside the delivery pipe before rotating it several times because the connector needs to face outward. Pay attention to avoid twisting the O-ring and confirm that the injector moves without resistance after installation because another O-ring might be required if the injector does not turn properly. The next step requires installation of six new insulators to the intake manifold while carefully inserting the fuel delivery pipe along with six fuel injectors onto the manifold. Avoid dropping any of the injectors. Secure the fuel delivery pipe to the intake manifold with its temporary 6 bolts before securing the 5 bolts at 21 Nm (214 kgf-cm, 15 ft-lbf). Afterwards, attach the 6 fuel injector connectors. The process for the fuel tube sub-assembly requires pushing tube connectors onto pipes until they click and inspecting both points for damage or foreign materials before securing the No. 2 fuel pipe clamp. Installation of the intake air surge tank should avoid applying oil to bolts because you should use a 5 mm hexagon socket to correctly torque the 4 bolts to 18 Nm (184 kgf-cm, 13 ft-lbf) before completing installation with 2 nuts and 2 bolts torqued to 21 Nm (214 kgf-cm, 15 ft-lbf) and 16 Nm (163 kgf-cm, 12 ft-lbf). The repair process requires installation of the connector followed by vacuum hose clamp bolt tightening to 5.4 Nm (55 kgf-cm, 48 in-lbf) and union connection to check valve hose then ventilation hose No. 2 insertion before clamp installation and throttle connection with motor body assembly. Next, connect the vapor feed hose and attach water by-pass hoses to throttle with motor body assembly. The air cleaner cap with air cleaner hose installation requires 3 clamps followed by tightening the hose clamp bolt to 5.0 Nm (51 kgf-cm, 44 in-lbf) before connecting the air flow meter connector alongside ventilation hose No. 1, 3 vacuum hoses and the fuel vapor feed hose No. 1. Once all previous components are in place, install the cowl top panel outer followed by the windshield wiper motor and link assembly then place the cowl top ventilator louver RH before putting the windshield wiper arm and blade assemblies for RH and LH. Attach the engine coolant while connecting the negative battery terminal cable before checking for coolant and fuel leakage. Complete assembly of the V-bank cover sub-assembly should start by inserting the clips from Point A to Point B.
