Ignition Coil

The first step for replacing ignition coil and spark plug components of the 2GR-FE engine starts with battery cable removal from the negative terminal. Additionally, extract all engine coolant from the system before the work begins. First detach the wiper arm head caps followed by extraction of front wiper arms from both right and left sides and finally the cowl top ventilator louver sub-assembly. Begin by removing the windshield wiper motor together with its link assembly and the No. 1 cowl top to cowl brace inner and the cowl top panel sub-assembly outer front. The service procedure requires front wiper arm head cap removal before proceeding to take off the V-bank cover sub-assembly, air cleaner cap sub-assembly, No. 1 engine under cover, and intake air surge tank assembly. The process for No. 1 surge tank stay removal requires first removing 2 bolts and a nut followed by disconnecting 2 harness clamps before taking out the bolt and No. 1 surge tank stay. After 6 ignition coil connector detachment and removal of the 6 bolts and ignition coils the system will be ready for removing the 6 spark plugs.

The installation of the 6 spark plugs for the 2GR-FE engine requires placing them in position and tightening them to 18 Nm (183 kgf-cm, 13 ft-lbf). Use the 6 bolts to install the 6 ignition coils while torquing them at 10 Nm (102 kgf-cm, 7 ft-lbf) and then fit the 6 ignition coil connectors. First install the No. 1 surge tank stay with 21 Nm (214 kgf-cm, 15 ft-lbf) torque on its specified bolt. Then implement 2 bolts, 2 clamps and a nut secured with 8.3 Nm (84 kgf-cm, 73 in-lbf). The technician should install the intake air surge tank assembly followed by the air cleaner cap sub-assembly before adding engine coolant. After cable connection to the negative terminal check for engine coolant leakage during inspection. Begin by putting in place the V-bank cover sub-assembly followed by the cowl top panel sub-assembly outer front and finally the No. 1 cowl top to cowl brace inner. You must install the windshield wiper motor along with its link assembly and then assemble the front wiper arm for LH and RH positions.

Remove the ignition coil assembly by disconnecting the 4 ignition coil connectors.

Remove the No. 1 engine cover.

Connect the cable to the negative battery terminal.

Reconnect the cable to the negative battery terminal.

Remove the luggage trim service hole cover.

Install the No. 1 engine cover sub-assembly.

Remove the 4 bolts and the 4 ignition coils.

First, remove the engine under cover assembly and the No. 1 engine under cover.

Begin by installing the 6 spark plugs with a torque of 18 Nm (183 kgf-cm, 13 ft-lbf).

Disconnect the cable from the negative battery terminal and wait at least 90 seconds to prevent airbag and seat belt pretensioner activation.

Begin by installing the 4 ignition coils with the 4 bolts, ensuring a torque of 9.0 N.m (92 kgf.cm, 80 in.lbf), then connect the 4 ignition coil connectors.

Install the 4 ignition coils using the 4 bolts, applying a torque of 10 Nm (102 kgf-cm, 7 ft-lbf), and connect the 4 ignition coil connectors.

Disconnect the cable from the negative battery terminal and wait at least 90 seconds to prevent airbag and seat belt pretensioner activation.

Inspect for engine coolant leaks.

Use a 16 mm spark plug wrench to remove the 4 spark plugs.

Continue by removing the intake air surge tank assembly and the No. 1 surge tank stay, which involves removing 2 bolts and a nut, disconnecting 2 harness clamps, and then removing the bolt and No. 1 surge tank stay.

Use a spark plug wrench to install the 4 spark plugs with a torque of 25 Nm (254 kgf-cm, 18 ft-lbf).

Install the 6 spark plugs with a torque of 18 Nm (183 kgf-cm, 13 ft-lbf).

Remove the No. 1 engine cover sub-assembly.
