Ignition Coil

Start ignition coil servicing by first removing the engine cover before disconnecting its electrical connectors between the ignition coil electrical connector and radio ignition interference capacitor connector. After pulling the spark plug wires from the ignition coil maintain a proper wire connection to the coil terminal to protect the system function. Proceed by unfastening the bolts which maintain the ignition coil in place and extract the coil unit. Check the ignition coil to determine whether carbon tracks exist and if it shows any signs of harm. The installation process requires performing the opposite steps used for removal to finish the operation.

Service work and repairs on the ignition coil begin by disconnecting the ground cable of the battery. Begin by taking out the cowl panel grille then disconnect the windshield wiper motor electrical connector. Remove the bolts for the cowl lower panel before reinstalling them tightly at 6 Nm (53 lb-in). Start by disconnecting the ignition coil electrical connector then twist each spark plug wire boot before pulling it upwards as a protection method against wire damage. Lastly check the wire positions to match the correct ignition coil terminal. Detach the six spark plug wires from the ignition coil before you remove its securing bolts which need to be tightened to 7 Nm (62 lb-in) after installation. The installation should end by following the reverse steps of the removal process.

A proper start for servicing or repairing ignition coils calls for cowl removal. First disconnect the ignition coil electrical connector and then carefully disconnect the spark plug wires by twisting pull-up to avoid damage to the spark plug wire. Unfasten the ignition coil bolts before extracting the coil from its position. Perform the opposite method of removal to install everything correctly.

A service operation on an ignition coil starts with the removal of the battery ground cable. You must uninstall the cowl panel grille before you disconnect the windshield wiper motor electrical connector. The bolts that secure the cowl top panel need removal before reinstallation when you should torque them to 6 Nm (53 lb-in). The ignition coil electrical connector must be disconnected while guiding the spark plug wire boots upward to protect the wires from damage and verifying proper connector placement on the correct coil terminal. Begin by detaching six spark plug wires from the ignition coil. After that remove the three bolts holding it until they reach a torque of 7 Nm. Tighten them another 7 Nm before reinstalling. The setup process ends with the execution of the reverse removal steps.

Start the ignition coil servicing process by removing the battery ground cable first. Start by removing the wiper motor followed by its pivot assembly before disconnecting the electrical connector from the ignition coil. The technician should twist the spark plug wire boots during upward pull to safeguard the wires before properly identifying the coil terminals by noting the wire positions. The process requires disconnecting six spark plug wires from the ignition coil followed by removal of three bolts securing the ignition coil which should be tightened to 7 Nm (62 lb-in) torque specification. The installation process ends by executing the reverse order of removal.

Remove the bolts and ignition coils.

Reverse the removal procedure to complete the installation.

Apply silicone brake caliper grease and dielectric compound to the inside of the spark plug wire boots to ensure proper function.

Begin by disconnecting the ignition coil electrical connector.

Twist the spark plug wire boots while pulling upward to prevent damage to the spark plug wires.

Begin by disconnecting the battery ground cable and the ignition coil electrical connector.

Disconnect the spark plug wires from the ignition coil, using a slight twisting motion to break the seal and ease removal.

Inspect the coils for cracks, carbon tracking, and dirt.

Reverse the removal procedure to install the ignition coil, applying silicone dielectric compound to the inside of the spark plug wire boots.

Disconnect the accelerator cable retaining clamp from the ignition coil stud bolt, then remove the bolts securing the ignition coil and take out the coil itself.

By twisting while pulling upward.

Reverse the removal procedure, ensuring to use a small, clean tool to coat the entire interior surface of the boot with silicone brake caliper grease.

Disconnect the heater hose support from the stud.

Remove the three bolts securing the ignition coil.

Reverse the removal procedure to complete the installation.
