Solution

1. Preparation

Tools Required: Socket set (10mm and 12mm), ratchet, spark plug socket, torque wrench, extension bar, anti-seize compound, dielectric grease.
Parts Required: New spark plugs (check owner's manual for specifications).
Ensure the engine is cool to avoid burns.

2. Remove Engine Cover

Locate the engine cover and remove any bolts or clips securing it.
Gently lift off the cover and set it aside.

3. Remove Old Spark Plugs

Locate the ignition coil on top of the spark plug.
Disconnect the electrical connector by pressing the clip and pulling it out.
Remove the ignition coil bolt using a 10mm socket and lift the coil out.
Use a spark plug socket to carefully unscrew and remove the old spark plug.

4. Install New Spark Plugs

Apply a small amount of anti-seize compound to the threads of the new spark plugs (avoid getting it on the electrode).
Hand-tighten the new spark plug into the cylinder head.
Use a torque wrench to tighten the spark plug to the manufacturer’s specified torque (typically around 13 lb-ft but check the manual for exact specifications).

5. Reinstall Ignition Coils and Engine Cover

Insert the ignition coil back into place and secure it with the bolt.
Reconnect the electrical connector to the ignition coil.
Repeat the process for all spark plugs.
Finally, place the engine cover back on and secure it with bolts or clips.

6. Reconnect Battery

Reconnect the negative battery terminal.
Ensure all tools are cleared from the engine bay before starting the vehicle.
