Solution

1. Preparation

Tools Required: Spark plug socket, ratchet, extension bar, torque wrench, gap gauge, dielectric grease.
Ensure the work area is clean and organized to avoid losing small parts.

2. Inspect the Spark Plugs

Sub-steps:
1. Examine the spark plugs for any signs of wear, such as excessive carbon buildup, oil fouling, or corrosion on the electrodes.
2. Check the ceramic insulator for cracks or damage.
3. Measure the gap between the electrodes using a gap gauge; it should match the specifications listed in the owner's manual.

3. Clean or Replace Spark Plugs

Sub-steps:
1. If the plugs are simply dirty, clean them using a wire brush or a specialized spark plug cleaner.
2. If they are worn or damaged, replace them with new spark plugs that meet the manufacturer’s specifications.
3. Apply a small amount of dielectric grease to the threads of the new spark plugs to ease future removal.

4. Reinstallation

Sub-steps:
1. Install the spark plugs by hand to avoid cross-threading, then tighten them to the manufacturer’s specified torque using a torque wrench (typically around 12-15 lb-ft).
2. Reconnect the spark plug wires or ignition coils, ensuring a secure connection.
3. Reinstall the engine cover if it was removed.

5. Reconnect Battery

Reconnect the negative battery terminal securely.
