  Q: How to install the spark plugs and related components on Toyota Sequoia?

  A: A 16 mm plug wrench should be used to bolt in the 8 spark plugs for the 2UZ-FE engine with a torque of 18 Nm (178 kgf-cm, 13 ft-lbf). Position the 8 Ignition Coil assemblies with the help of 8 bolts which need to be torqued to 7.5 Nm (76 kgf-cm, 66 in-lbf). Afterward, connect the 8 ignition coil assembly connectors. Next install the Bank 2 air switching valve assembly before attaching both the Bank 2 air tube and No. 2 air injection system hose. Proceed to connect the No. 1 water by-pass pipe before installing the front fender apron seal right-hand side. The technical sequences includes installing the air switching valve assembly for Bank 1 and the No. 3 air tube and the No. 2 air hose then putting on the front fender apron seal LH. To finish the installation place the throttle body cover assembly together with the air cleaner hose assembly.
