Installation of the 4
Spark Plugs on the 2AZ-FE engine control must be done with 19 Nm (194 kgf-cm, 14 ft-lbf) of torque after which installation of the 4 ignition coils begins using 4 bolts with 9.0 Nm (92 kgf-cm, 80 in-lbf) torque followed by connecting the 4 ignition coil connectors. Install 4 ignition coils to their mounting place with 4 bolts while tightening to 9.0 Nm (92 kgf-cm, 80 in-lbf) and link all 4 ignition coil connectors. Installing the last part involves fixing the No. 1 engine cover sub-assembly.
