• Q: How to remove the Air Injection Pump on 2008 Toyota Sequoia?

  A: Before removing the Air Injection Pump operating personnel must conduct a fuel system pressure discharge. Start by taking out the front wiper blades and arms from right and left sides then perform the removal of front fender to cowl side seals from both sides. The procedure continues with front wiper motor and link assembly separation followed by removal of the cowl top ventilator louver sub-assembly. The Air Injection Pump requires removal after taking out both front cowl top outer panel sub-assembly and the No. 1 engine under cover. After coolant drainage the technician should remove throttle body cover sub-assembly, air cleaner hose assembly, vacuum hose assembly, and No. 2 water by-pass pipe. The removal process of the intake manifold starts by disconnecting both the fuel main tube and fuel return tube. The process to remove the water by-pass pipe sub-assembly starts with disconnecting the connector clamp followed by bolt removal and sub-assembly and O-ring extraction. The removal of Bank 1 air pump assembly requires agents to remove the 2 clips from the No. 1 air injection system hose before disconnecting the air pump assembly connector and taking out 2 bolts and 2 nuts that secure the assembly. The removal of the air pump bracket requires users to disassemble its 3 bolts, 3 collars along with 3 insulators. To access the right side front fender liner you must first remove 9 clips before using a clip remover to remove 2 clips attaching the No. 2 air injection system hose. Afterward, fold back the fender apron seal while disconnecting the air pump assembly connector and removing the air injection system hose. The air pump assembly removal for Bank 2 demands the unfastening of its bolt and two nuts. End the air pump inlet procedure by removing two bolts and unclamping the No. 1 air injection system hose before extracting all three air pump insulators and the air pump assembly from the No. 1 air pump bracket.
