  Q: How to remove the Air Injection Pump on Toyota Sequoia?

  A:

  The first step to remove the Air Injection Pump requires discharging fuel system pressure. The next step includes removing the front wiper arm and blade assembly from both right and left sides together with both front fender to cowl side seals. You must remove both the cowl top ventilator louver sub-assembly and the front Wiper Motor together with the link assembly. The first step requires eliminating both the front cowl top outer panel sub-assembly and the No. 1 engine under cover from the vehicle. Engine coolant drainage needs to occur before removing the throttle body cover sub-assembly along with the air cleaner hose assembly and vacuum hose assembly and the No. 2 water by-pass pipe. The Intake Manifold needs removal after both fuel return tube and fuel main tube disconnect. The procedure to remove the water by-pass pipe sub-assembly includes disconnecting the connector clamp before removing the bolt and pulling out the assembly to detach the O-ring. The next step involves removing the No. 1 air injection system hose by unclipping its 2 retention devices. The Bank 1 air pump assembly requires disconnecting its connector followed by removal of two bolts and two nuts. The air pump bracket can be removed after extracting all 3 bolts together with the 3 collars and 3 insulators. Ninth retainers must be removed from the front fender liner on the right side before proceeding. The installation of the No. 2 air injection system hose requires a clip remover tool to remove two clips and flipping the fender apron seal before disconnecting the air pump assembly connector and releasing two clamps and finally extracting the hose. Block out the removing process for the Bank 2 air pump assembly which consists of one bolt combined with two nuts. Finish the air pump inlet work by unbolting the 2 screws before disconnecting the No. 1 air injection system hose and No. 1 air pump bracket and removing its 3 insulators from the bracket.

  Q: How to install the Air Injection Pump on Toyota Sequoia?

  A:

  First install the No. 1 air pump bracket before attaching the pump to its position through 3 air pump insulators and a clamp. Mount two bolts for the No. 1 air injection system hose and air pump inlet according to 8.0 Nm (82 kgf-cm, 71 in-lbf) torque specifications before ensuring that the insert hose reaches its complete stoppers position. The Bank 2 air pump assembly requires users to insert the slot onto the stud and bracket tab before tightening two nuts, a bolt, and torquing to 18 Nm for the bolt and 12 Nm for the nuts. Following the step at connect the air pump assembly connector install the No. 2 air injection system hose and secure it with 2 clamps before placing the fender apron seal using 2 clips. After installation of the front fender liner RH using 9 clips install the air pump bracket with 3 insulators and 3 collars secured by 3 bolts which need to be torqued to 10 Nm (102 kgf-cm, 7 ft-lbf). The Bank 1 air pump assembly must be fastened with 2 bolts and 2 nuts with torque set to 16 Nm (163 kgf-cm, 12 ft-lbf) and with the air pump assembly connector attached. Follow hose installation with the application of soapy water on a fresh O-ring for the water by-pass pipe sub-assembly before pushing it in using a bolt which will be torqued to 18 Nm (184 kgf-cm, 13 ft-lbf) and followed by connector clamp attachment. Perform Intake Manifold and fuel main tube and fuel return tube installation before extracting the No. 2 water by-pass pipe. Start the process by connecting the vacuum hose assembly and installing the air cleaner hose assembly before adding engine coolant for leak inspection. The procedure ends with the installation of the No. 1 engine under cover alongside the throttle body cover sub-assembly and 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 (RH and LH), and front wiper arm and blade assemblies (RH and LH).
