Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Remove Engine Cover (if applicable)

Locate all fasteners securing the engine cover.
Use a socket set to remove the fasteners.
Carefully lift off the engine cover and set it aside.

3. Remove Old Spark Plugs

Identify the spark plug wires or ignition coils.
Disconnect the spark plug wires or remove the ignition coils, noting their positions.
Use a spark plug socket and ratchet to carefully unscrew and remove each spark plug.

4. Inspect and Replace

Inspect the old spark plugs for signs of wear (e.g., electrode wear, carbon deposits).
Compare the old spark plugs to the new ones for correct specifications.
Apply anti-seize lubricant to the threads of the new spark plugs.
Hand-tighten the new spark plugs, then torque to manufacturer specifications (usually around 12-15 lb-ft).

5. Reassemble

Reconnect the ignition coils or spark plug wires in their original positions.
Reinstall the engine cover and secure it with the fasteners.
Reconnect the battery.
