2009 Toyota Sequoia Air Injection Pump Parts Q&A

• Q: How to install the air injection pump on 2009 Toyota Sequoia?

  A: First install the No. 1 air pump bracket then secure the pump with 3 air pump insulators attached by a clamp. First place the No. 1 air injection system hose along with the air pump inlet through 2 bolts which need a torque of 8.0 Nm (82 kgf-cm, 71 in-lbf) while verifying the insert hose reaches the stoppers completely. The installation of Bank 2 air pump assembly requires slotting the component over the stud and bracket tab followed by bolting with 2 nuts and a single bolt which needs torquing to 18 Nm (184 kgf-cm, 13 ft-lbf) for the bolt and 12 Nm (122 kgf-cm, 9 ft-lbf) for the nuts. Connect the air pump assembly connector to the No. 2 air injection system hose and secure it with two clamps followed by fender apron installation with two clips. Deal with the front fender liner installation by applying 9 clips followed by installing the air pump bracket with three insulators and three collars using three bolts torqued to 10 Nm. The Bank 1 installation requires the air pump assembly with (2 bolts and 2 nuts) that need 16 Nm (163 kgf-cm, 12 ft-lbf) torque before connector attachment. The process to install the No. 1 air injection system hose requires the application of a new O-ring to the water by-pass pipe sub-assembly where soapy water aids installation before securing the sub-assembly with a bolt torqued to 18 Nm (184 kgf-cm, 13 ft-lbf) and connecting the connector clamp. Install the intake manifold and add the fuel main tube as well as the fuel return tube to the system. The air cleaner hose assembly must be installed first followed by connecting the vacuum hose assembly then removing the No. 2 water by-pass pipe. The system will receive engine coolant before technicians check for any fluid leakage. The last installation steps include adding the No. 1 engine under cover together with throttle body cover sub-assembly as well as front cowl top outer panel sub-assembly, front wiper motor and link assembly, cowl top ventilator louver sub-assembly, front fender to cowl side seals (both RH and LH), and front wiper arm and blade assemblies (both RH and LH).
