Solution

1. Preparation

Tools Required: Socket set, torque wrench, ratchet extension, spark plug socket, anti-seize compound, dielectric grease, clean cloth.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shock.

2. Remove Engine Cover

Sub-steps:
1. Use a socket wrench to remove the bolts securing the engine cover (if applicable).
2. Carefully lift off the engine cover and set it aside.

3. Access Spark Plugs

Sub-steps:
1. Locate the ignition coil packs on top of the engine where the spark plugs are situated.
2. Disconnect the electrical connectors from each ignition coil by pressing the release tab and pulling them off.

4. Remove Ignition Coils

Sub-steps:
1. Remove the bolts securing each ignition coil using the appropriate socket.
2. Gently pull each coil straight out of the spark plug well to avoid damaging them.

5. Remove Old Spark Plugs

Sub-steps:
1. Using a spark plug socket and ratchet, carefully unscrew each spark plug from the cylinder head.
2. Inspect the old spark plugs for signs of wear or fouling.

6. Install New Spark Plugs

Sub-steps:
1. Apply a small amount of anti-seize compound to the threads of the new spark plugs (if recommended).
2. Carefully screw in the new spark plugs by hand to avoid cross-threading, then torque to manufacturer specifications (typically around 13 ft-lbs).
3. Ensure the spark plugs have the correct gap as specified by the manufacturer.

7. Reinstall Ignition Coils

Sub-steps:
1. Place each ignition coil back into its respective spark plug well.
2. Secure each coil with its retaining bolt and reconnect the electrical connector.

8. Reinstall Engine Cover

Sub-steps:
1. Place the engine cover back on and secure it with the previously removed bolts.

9. Reconnect Battery

Reconnect the negative battery terminal and ensure it is tight.
