Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to ensure safety.

2. Remove Engine Cover

Remove any engine cover if equipped, by unscrewing any retaining bolts or clips.
Carefully lift off the cover and set it aside.

3. Remove Spark Plug Wires or Ignition Coils

If equipped with spark plug wires, carefully disconnect each wire from the spark plugs. Label them for easier reinstallation.
If equipped with ignition coils, remove the bolts securing the coils and lift them off the spark plugs.

4. Remove Spark Plugs

Use a spark plug socket and ratchet to remove the spark plugs from the cylinder head.
Turn counterclockwise to loosen and remove each spark plug carefully.

5. Inspect and Install New Spark Plugs

Inspect the old spark plugs for wear patterns.
Set the gap on the new spark plugs according to manufacturer specifications using a feeler gauge.
Apply a small amount of anti-seize lubricant on the threads of the new spark plugs (if recommended).
Install the new spark plugs by hand to avoid cross-threading, then tighten with the spark plug socket to the specified torque (usually around 13-15 ft-lbs).

6. Reinstall Components

Reattach the ignition coils or spark plug wires, ensuring they are connected securely.
Replace the engine cover if removed, securing it with the appropriate bolts or clips.
Reconnect the negative battery terminal.
