• Q: How to remove the fuel injector on 2008 Toyota Sienna?

  A: The first step to remove the fuel injector from a 2GR-FE engine starts with discharging fuel system pressure while disconnecting the negative battery terminal cable. The next step requires users to detach the No. 1 engine under cover followed by draining the engine coolant from the system. Start by taking off the wiper arm head cap from the front followed by right and left front wiper arm removal then move onto the cowl top ventilator louver sub-assembly. Begin by removing the windshield wiper motor and link assembly and proceed to extract the No. 1 cowl top to cowl brace inner by uninstalling its 2 bolts. You need to start by removing the cowl top panel sub-assembly outer front through a process of wire harness clamp disconnection and fuel pump resistor connector detachment and 7 bolt removal. Your task begins with taking out the V-bank cover sub-assembly and then moving to the air cleaner cap sub-assembly where you must disconnect 3 vacuum hoses and remove the No. 2 ventilation hose and air cleaner hose band then release the EVAP vacuum hose and remove 2 bolts. To remove the intake air surge tank assembly use a 5 mm socket hexagon wrench which first requires removing four bolts then two nuts and two bolts afterward followed by the gasket removal. Disconnect the fuel tube sub-assembly by unclamping the No. 2 fuel pipe and drawing out the fuel pipe until completion without allowing dirt to penetrate the quick connector. To remove the fuel injector assembly, first disconnect the 6 fuel injector connectors then remove 5 bolts that let go of the fuel delivery pipe sub-assembly along with its 6 fuel injectors while keeping an eye out for drops. Wrap up the process by taking away the 6 injector vibration insulators from the intake manifold and extracting the fuel injectors from the fuel delivery pipe sub-assembly followed by removing the 6 O-rings from the fuel injectors.
