2
Disconnect the negative battery terminal to prevent electrical shock.
3
Remove engine cover (if applicable) to access the spark plugs.
4
Inspect the existing spark plugs for wear and carbon buildup.

Solution

1. Preparation

Tools Required: Socket set, ratchet, spark plug socket, torque wrench, extension bar, dielectric grease.
Parts Required: New spark plugs (check specifications for correct type), possibly new spark plug wires or coils if damaged.
Disconnect the negative battery terminal using a wrench.

2. Remove Engine Cover

If equipped, remove any screws or clips holding the engine cover in place.
Carefully lift the cover off and set it aside.

3. Remove Old Spark Plugs

Locate the spark plug wires or ignition coils on top of the spark plugs.
If using wires, gently pull them off the spark plugs; label them if necessary to ensure correct reinstallation.
For ignition coils, remove the bolts holding the coils in place and disconnect the electrical connectors.
Use the spark plug socket and ratchet to carefully unscrew and remove each old spark plug. Turn counterclockwise until they are free.

4. Install New Spark Plugs

Apply a small amount of dielectric grease to the threads of the new spark plugs to ensure easy removal in the future.
Hand-tighten each new spark plug into the cylinder head, then use the torque wrench to tighten them to the manufacturer's specification (typically around 13-16 lb-ft).

5. Reinstall Ignition Coils or Wires

If using ignition coils, reconnect the electrical connectors and secure them with the bolts.
If using spark plug wires, reconnect them ensuring they are seated properly over the new plugs.

6. Reassemble Engine Cover

Place the engine cover back on and secure it with screws or clips as necessary.
Reconnect the negative battery terminal.
