2007 Toyota Sienna Ignition Coil Parts Questions & Experts Answers

• Q: How to service the ignition coil on 2007 Toyota Sienna?

  A: Application of servicing procedures begins by disconnecting the cable from the negative battery terminal followed by draining engine coolant. Service begins with removing the front wiper arm head cap then moving to right and left front wiper arms and continuing with the cowl top ventilator louver subassembly followed by the windshield wiper motor and link assembly. The service begins with removing the No. 1 cowl top to cowl brace inner and cowl top panel sub-assembly outer front and No. 1 engine under cover and V-bank cover sub-assembly while also removing the air cleaner cap sub-assembly and intake air surge tank assembly with its No. 1 surge tank stay by first removing the 2 bolts and nut and disconnecting the 2 harness clamps before removing the bolt and No. 1 surge tank stay. To achieve ignition coil assembly removal begin by disconnecting 6 ignition coil connectors then move to take out 6 bolts along with 6 ignition coils followed by eliminating 6 spark plugs. The first step is to mount the 6 spark plugs using 18 Nm torque (183 kgf.cm, 13 ft. lbs.) before installing the ignition coil assembly through a bolt torque of 10 Nm (102 kgf.cm, 7 ft. lbs.) while connecting all 6 ignition coil connectors. Start by attaching the No. 1 surge tank stay without lubricating its bolt before tightening it to 21 Nm (214 kgf.cm, 15 ft. lbs.). The assembly requires two bolts and two clamps together with the nut which needs to be torqued to 8.3 Nm (84 kgf.cm, 73 in. lbs.) after the bolt reaches its specified torque. Afterward, install the intake air surge tank assembly before putting on the air cleaner cap sub-assembly followed by engine coolant addition then reconnecting the negative battery cable. Debugging requires a leak check on engine coolant before installing the V-bank cover sub-assembly and cowl top panel sub-assembly outer front and No. 1 cowl top to cowl brace inner and windshield wiper motor and link assembly, along with the front wiper arms.
