Solution

1. Preparation

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

2. Remove Engine Cover (if applicable)

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

3. Access Spark Plugs

Locate the ignition coils or spark plug wires leading to each spark plug.
If equipped with ignition coils, disconnect the electrical connectors and remove the bolts using a socket wrench.
Carefully pull the ignition coils out to expose the spark plugs.

4. Remove Old Spark Plugs

Use a spark plug socket and ratchet to unscrew the old spark plugs from the engine.
Inspect each plug for wear and carbon buildup.

5. Install New Spark Plugs

Apply a small amount of anti-seize compound to the threads of the new spark plugs (if recommended).
Hand-tighten each spark plug into the cylinder head, then use a torque wrench to tighten to the manufacturer's specified torque (typically around 15-20 lb-ft).

6. Reinstall Ignition Components

Replace the ignition coils back into their respective positions and secure them with bolts.
Reconnect the electrical connectors to the ignition coils.

7. Reattach Engine Cover

Place the engine cover back and secure it with the bolts removed earlier.

8. Reconnect Battery

Reconnect the negative battery terminal.
