Solution

1. Preparation

Tools Needed:
- Socket set
- Torque wrench
- Multimeter
- Screwdrivers
Safety Warnings:
- Disconnect the battery before beginning work to prevent electrical shock or short circuits.

2. Remove Engine Cover (if applicable)

Locate the retaining bolts or clips securing the engine cover.
Use a socket or screwdriver to remove them.
Carefully lift the engine cover off and set it aside.

3. Remove Ignition Coil

Identify the ignition coil(s) to be replaced (usually at the top of the engine, above the spark plugs).
Disconnect the electrical connector from the ignition coil by pressing the tab and pulling it off.
Remove the mounting bolt(s) securing the ignition coil using a socket.
Gently pull the ignition coil out of the spark plug well.

4. Install New Ignition Coil

Apply a small amount of dielectric grease to the rubber boot of the new ignition coil to ensure a good seal.
Insert the new ignition coil into the spark plug well until it is fully seated.
Reinstall the mounting bolt(s) and torque them to the manufacturer’s specifications (usually around 10-15 ft-lbs, but verify with the service manual).
Reconnect the electrical connector to the ignition coil until it clicks into place.

5. Reassemble Engine Components

If applicable, replace the engine cover by aligning it and securing it with the previously removed bolts or clips.
Reconnect the battery terminals.
