Solution

1. Preparation

Tools Required: Socket set, torque wrench, ratchet, extension bar, spark plug socket, anti-seize compound, dielectric grease.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool completely before beginning work.
Remove any engine covers obstructing access to the spark plugs.

2. Remove Old Spark Plugs

Locate Spark Plugs: Identify the location of the spark plugs on the engine.
Disconnect Ignition Coils: Carefully disconnect the electrical connectors from the ignition coils.
Remove Ignition Coils: Unbolt and remove the ignition coils using a socket and ratchet. Keep track of the order for reinstallation.
Remove Spark Plugs: Use a spark plug socket with an extension to carefully unscrew each spark plug. Avoid damaging the cylinder head.

3. Inspect and Prepare New Spark Plugs

Inspect New Spark Plugs: Ensure that the new spark plugs are the correct type and gap them according to the manufacturer's specifications.
Apply Anti-Seize Compound: Lightly coat the threads of the new spark plugs with anti-seize compound to prevent galling during future removal.

4. Install New Spark Plugs

Install Spark Plugs: Insert each new spark plug into the cylinder head and hand-tighten.
Torque Spark Plugs: Using a torque wrench, tighten the spark plugs to the manufacturer's specified torque (typically around 13-15 ft-lbs). Be careful not to over-tighten.
Reinstall Ignition Coils: Position the ignition coils back onto the spark plugs and bolt them down securely.
Reconnect Ignition Coils: Reconnect the electrical connectors to the ignition coils, ensuring a snug fit.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and listen for any irregularities.
