Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool to avoid burns.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Access the Spark Plugs

Tools Required: Socket set, extension, torque wrench.
Remove the engine cover by unscrewing any bolts or clips securing it.
Carefully lift off the cover and set it aside.

3. Remove Spark Plugs

Tools Required: Spark plug socket, ratchet, torque wrench.
Locate the spark plugs on the engine.
Use the spark plug socket and ratchet to unscrew each spark plug from the cylinder head, turning counterclockwise.

4. Inspect Spark Plugs

Examine each spark plug for wear indicators:
- Check for carbon deposits on the electrode.
- Look for excessive wear or cracks in the ceramic insulator.
- Measure the gap with a feeler gauge; it should match the specifications in the owner's manual (typically around 0.028 - 0.031 inches).
If any spark plugs show significant wear or damage, they should be replaced.

5. Install New Spark Plugs (if needed)

If replacing, insert the new spark plugs by hand to avoid cross-threading.
Tighten the spark plugs to manufacturer specifications using a torque wrench (usually around 20-30 Nm, check the manual for exact value).
Reinstall the engine cover and secure it with bolts or clips.

6. Reconnect Battery

Reconnect the negative terminal of the battery.
Ensure all tools are removed from the engine bay.
