Solution

1. Preparation

Tools Required: Spark plug socket, ratchet, extension, torque wrench, dielectric grease, compressed air (optional), and a vacuum cleaner.
Disconnect the negative battery terminal to prevent any electrical short.
Ensure the engine is cool to avoid burns.

2. Access the Spark Plugs

Sub-steps:
1. Remove any plastic engine cover by unscrewing the fasteners.
2. If necessary, remove the intake manifold or other components that obstruct access to the spark plug wells.

3. Remove Old Spark Plugs

Sub-steps:
1. Use compressed air to blow out any debris from around the spark plug wells to prevent contamination.
2. Using the spark plug socket and ratchet, carefully unscrew each spark plug. Turn counterclockwise until loose.
3. Remove the spark plug from the well and inspect for wear or damage.

4. Install New Spark Plugs

Sub-steps:
1. Check the gap on the new spark plugs and adjust if necessary according to manufacturer specifications.
2. Apply a small amount of dielectric grease to the threads of the new spark plugs to facilitate easier future removal.
3. Hand-thread the new spark plugs into the wells to avoid cross-threading.
4. Tighten each spark plug with a torque wrench to the specified torque (typically around 13-15 lb-ft).

5. Reassemble Components

Sub-steps:
1. Reinstall any components or covers that were removed to access the spark plugs.
2. Ensure all fasteners are securely tightened.

6. Reconnect Battery and Test

Sub-steps:
1. Reconnect the negative terminal of the battery.
2. Start the engine and let it idle; listen for any abnormal sounds and ensure it runs smoothly.
