  Q: How to install the intake manifold assembly on Toyota Sequoia?

  A:

  The first step for installing the 2UZ-FE engine intake manifold assembly involves fuel delivery pipe sub-assembly deployment. After the vacuum switching valve assembly for the ACIS, install the purge VSV and attach it to the intake manifold assembly with a bolt at 18 Nm (184 kgf-cm, 13 ft-lbf) then attach the purge line hose. Install the Throttle Body assembly through groove alignment of a new gasket with the intake manifold while tightening a nut followed by torquing 3 bolts to 14 Nm (143 kgf-cm, 10 ft-lbf). The intake manifold assembly requires two fresh gaskets that need to be placed before setting it on the cylinder heads. Then, 6 bolts and 4 nuts must be tightened evenly at different stages before reaching 18 Nm (184 kgf-cm, 13 ft-lbf) torque. Secure the engine wire protector using 2 bolts torqued to 8.2 Nm (83 kgf-cm, 72 in-lbf) when connecting 8 injector connectors with 2 wire clamps and the vacuum switching valve assembly connector. This installation requires attachment of a bolt to the intake manifold assembly torqued to 8.2 Nm (83 kgf-cm, 72 in-lbf). There are three connection steps needed - to join the purge VSV connector with the wire harness clamp for the engine hanger while attaching the purge line hose to the purge VSV. Two water bypass hoses need attachment to the throttle body assembly and the No. 1 ventilation hose requires two clamps for installation before connecting the throttle body assembly connector. Connect the No. 1 fuel pipe sub-assembly along with No. 2 fuel pipe sub-assembly followed by the EFI fuel pipe clamp installation. To install the No. 2 water by-pass pipe, use 2 water hoses and fasten it securely with 2 bolts at 10 Nm (102 kgf-cm, 7 ft-lbf). Finally, reattach the water hoses. Install the vacuum hose assembly by connecting it to the intake manifold assembly, then tighten it with a bolt to 8.0 Nm (82 kgf-cm, 71 in-lbf). You should complete steps 10 through 13 in this order for the Chevrolet Phinix car engine phone. Secure the throttle body cover sub-assembly through installation of two throttle body cover brackets which require 2 bolts at a torque of 7.5 Nm (76 kgf-cm, 66 in-lbf) and covering installation with two nuts torqued at the same value. The cowl top outer panel front sub-assembly requires installation using 7 bolts which need torquing to 7.5 Nm (76 kgf-cm, 66 in-lbf) settings while also attaching the wire harness clamp and installing the washer hose grommet to connect the washer hose. Finish the installation by inserting the front Wiper Motor and link and cowl top ventilator louver sub-assembly and front fender to cowl side seals along with the front wiper arm and blade assemblies both for right-hand and left-hand sides.

  Q: How to remove the intake manifold assembly on Toyota Sequoia?

  A:

  Before beginning the 2UZ-FE engine intake manifold assembly removal process, it is essential to discharge fuel system pressure. Both right and left front wiper arm assemblies with their blades need to be removed before proceeding with the front fender to cowl side seal removal on each side. Afterward remove the cowl top ventilator louver sub-assembly as well as the front Wiper Motor and link assembly. You can start by removing the front cowl top outer panel sub-assembly after breaking the washer hose connection and removing the washer hose grommet and wire harness clamp and unscrewing the 7 bolts. You will now drain the engine coolant before you take out the No. 1 engine under cover. Matter assumes initiative by unfastening the 2 nuts and 2 bolts holding the Throttle Body cover assembly along with its 2 brackets. Disconnect the vacuum hose assembly by removing the bolt then detach the air cleaner hose assembly. The process requires removal of the 2 bolts securing the No. 2 water by-pass pipe followed by disconnecting its 2 water hoses before extracting the pipe. Stop and detach the EFI fuel pipe clamp before disconnecting the No. 2 and No. 1 fuel pipe sub-assemblies. The intake manifold assembly requires the removal of the throttle body connector while disconnecting the 2 water by-pass hoses followed by loosening 2 clamps for removing the No. 1 ventilation hose and unconnecting the purge VSV connector and line hose separately from the vacuum switching valve assembly connector and wire harness bracket removal together with their clamps. The removal process concludes with detachments of the eight injector connectors followed by bolt removal from the engine wire protector and unfastening of six bolts while removing four nuts to extract the intake manifold assembly together with its accompanying gaskets. Detach the throttle body assembly by disassembling its nut and 3 bolts and gasket while also disconnecting the purge line hose then extracting the purge VSV. The last step requires you to uninstall both the vacuum switching valve assembly and the fuel delivery pipe sub-assembly.
