Question 1

How to remove the fuel injector on Toyota Sienna?

Accepted Answer

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.

Question 2

How to service and repair fuel injectors on Toyota Sienna?

Accepted Answer

The initial steps for servicing the fuel injectors begin by taking out three components: outer front cowl top panel assembly together with air cleaner cap and hose as well as air intake chamber assembly. Safely disconnect each injector connector and remove air assist tubings and pipe by separating the air assist pipe from its bracket on the first fuel pipe and removing hoses from the intake manifold. Caring for leaking fuel requires disconnecting the fuel inlet pipe from the filter after which you should position a container to collect any spills. The delivery pipes together with six injectors and fuel pipe can be extracted by dismantling five bolts before removing four spacers from the intake manifold. Remove six delivery pipe injectors before taking off their pair of O-rings together with pair of grommets for each injector. Begin by preparing each injector with fresh grommets and new insulators followed by application of spindle oil or gasoline thinly on both fresh O-rings which need to be installed onto each injector. Place spindle oil or gasoline on the delivery pipe area next to the injector O-ring then while rotating the injector move it into the delivery pipes for complete installation of all six components with their connectors facing outward. Install the four spacers onto the intake manifold while coating the injector O-ring areas with spindle oil or gasoline before placing delivery pipes with a fuel pipe containing six injectors on the intake manifold. Test install the delivery pipe and fuel pipe fasteners with O-rings first to verify injector rotation before exchanging rubber gaskets that affect smooth operation. The four delivery pipe bolts should be tightened to 10 Nm torque and the fuel pipe bolt requires 19.5 Nm torque. Apply two new gaskets to the fuel filter where the fuel inlet hose connects while securing the union bolt with 29 Nm (300 kg.cm, 22 ft.lb) torque. Fasten the end of the air assist hoses to their positions on the intake manifold followed by mounting the air assist pipe onto the bracket positioned near the No.1 fuel pipe. I will complete the procedure by attaching the injector connectors while installing the air intake chamber assembly followed by the air cleaner cap with hose and outer front cowl top panel assembly before verifying for fuel leaks.
