2008 Toyota Sienna Parts Questions & Experts Answers

• Q: How to install the ignition coil and spark plugs on 2008 Toyota Sienna?

  A: The proper installation of spark plugs for a 2GR-FE engine entails using 18 Nm torque for 6 spark plugs. First connect the 6 ignition coil connectors and then install the 6 ignition coils using their 6 bolts with initial torque at 10 Nm (102 kgf-cm, 7 ft-lbf). Begin by installing the bolt to the No. 1 surge tank stay before tightening it to 21 Nm (214 kgf-cm, 15 ft-lbf). Follow this step by installing two bolts and two clamps and their nut with 8.3 Nm (84 kgf-cm, 73 in-lbf) torque. You should install the intake air surge tank assembly followed by the air cleaner cap sub-assembly while performing engine coolant addition. Verify that the engine remains leak-free during the inspection of coolant leaks. Then connect a cable to the negative battery terminal. The maintenance process includes installation of the V-bank cover sub-assembly and cowl top panel sub-assembly outer front followed by addition of the No. 1 cowl top to cowl brace inner. The final installation steps include windshield wiper motor link assembly installation together with front wiper arm installation for left-hand and right-hand sides.
