  Q: How to install the fuel injector assembly on Toyota Venza?

  A:

  The first step for installing new O-rings on fuel injectors requires a thin petroleum layer to lubricate them before putting each ring into position. Work with a thin layer of gasoline or spindle oil both on the fuel delivery pipe area that touches the fuel injector O-ring and on the O-ring itself before installing the fuel injectors onto the pipe while confirming the O-ring remains intact and undamaged. A broken fuel injector will become stiff to rotate so you must replace the O-ring. When installing the fuel delivery pipe sub-assembly begin with mounting 4 new injector vibration insulators to the cylinder head followed by the 2 fuel delivery spacers which have a longer protrusion on the cylinder head side. Secure the fuel delivery pipe with its 4 fuel injectors onto the cylinder head while maintaining the installation of 2 temporary bolts to achieve this step before checking for dropped injectors. Verify that the fuel injector moves easily before tightening the 2 bolts by applying torque to 21 Nm (214 kgf-cm, 15 ft-lbf). The 2 wire harness brackets should be installed using 2 bolts that reach 10 Nm torque (102 kgf-cm, 7 ft-lbf) whereas the 3 connectors and 4 fuel injector connectors should be connected after which the 2 clamps should be installed to join the wire harness. Squeeze the tube connector onto the pipe framework to secure attachment while also verifying there are no foreign objects or damages on either connecting piece. Test the connection by trying to disassemble the components. Fasten the fuel tube sub-assembly along with the No. 1 fuel pipe clamp onto the fuel hose clamp. Follow the installation procedure for the air cleaner cap sub-assembly and the No. 1 vacuum switching valve assembly and the No. 1 engine cover sub-assembly and the outer cowl top panel. After mounting the windshield Wiper Motor and link assembly, connect the cable to the negative battery terminal while checking if initializations are necessary upon completion of reconnection. Finally, inspect for fuel leaks.

  Q: How to remove the fuel injector on Toyota Venza?

  A:

  A proper first step for removing a fuel injector involves discharging the fuel system pressure. After negative battery cable disconnection you should note that select systems need initialization following reinstallation of the cable. Start by removing the windshield Wiper Motor assembly together with the link before proceeding with the outer cowl top panel. The technician should disconnect both the No. 1 engine cover sub-assembly and the No. 1 vacuum switching valve assembly. The fuel tube sub-assembly requires removal by unclamping the No. 1 position pipe followed by disconnecting the tube connector from the pipe while inspecting for foreign objects which should be cleaned from the connector area. Do not use tools on connector and pipe separation while also refraining from applying force through bending or hose twisting. When connector and pipe do not disconnect easily you should turn the connector carefully while pinching it until separation and place them both in a plastic bag to protect them from damage. The wiring harness separation involves unclasping the 4 fuel injector connectors and 3 supplementary connectors and 2 bolts together with detaching the 2 wire harness brackets followed by unclasping the 2 fuel delivery pipe clamps. First detach the vacuum switching valve assembly followed by disconnecting the fuel delivery pipe sub-assembly through the removal of its 2 bolts and extraction of the fuel delivery pipe with its 4 fuel injectors while being attentive to not allow the injectors to fall. Finish the process by removing both fuel delivery spacers along with the four injector vibration insulators from the cylinder head before extracting the four fuel injectors from the pipeline.
