Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Engine Cover (if applicable)

Locate the engine cover on top of the engine.
Use a socket set to remove any bolts securing the engine cover.
Carefully lift the cover off and set it aside.

3. Access the Ignition Coil

Identify the ignition coils located on top of the engine, typically adjacent to the spark plugs.
If necessary, remove any components obstructing access (e.g., air intake duct).

4. Remove the Ignition Coil

Disconnect the electrical connector from the ignition coil by pressing the release tab and pulling it off.
Remove the bolt securing the ignition coil using a socket or wrench.
Gently pull the ignition coil straight out of the cylinder head.

5. Install New Ignition Coil

Apply a small amount of dielectric grease to the inside of the new ignition coil boot.
Insert the new ignition coil into the cylinder head until it is fully seated.
Reinstall the securing bolt and tighten to the manufacturer's specified torque (typically around 7.5 lb-ft).
Reconnect the electrical connector until it clicks into place.

6. Reassemble and Test

If removed, reinstall any components that were taken off to access the ignition coil.
Reinstall the engine cover and secure with bolts.
Reconnect the negative battery terminal.
