Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

Tools Required:

Socket set
Torque wrench
Spark plug socket
Feeler gauge
Ratchet and extensions
Anti-seize lubricant (optional)

2. Remove Engine Cover

Locate the screws or bolts holding the engine cover in place.
Use the socket set to remove these screws/bolts.
Gently lift off the engine cover and set it aside.

3. Remove Old Spark Plugs

Identify the correct spark plug locations.
Use the spark plug socket attached to the ratchet to unscrew and remove each spark plug.
Carefully pull the spark plug wire or coil pack off of each spark plug if applicable.

4. Inspect and Prepare New Spark Plugs

Check the gap of the new spark plugs using a feeler gauge and adjust as necessary to the manufacturer's specifications.
Optionally, apply a small amount of anti-seize lubricant to the threads of the new spark plugs to prevent seizing.

5. Install New Spark Plugs

Insert each new spark plug into the cylinder head by hand to avoid cross-threading.
Use the torque wrench to tighten each spark plug to the manufacturer's specified torque (usually around 20-25 Nm for most spark plugs, check the service manual for specifics).
Reconnect the spark plug wires or coil packs ensuring they click into place.

6. Reinstall Engine Cover

Place the engine cover back onto the engine.
Secure it using the screws or bolts previously removed.

7. Reconnect Battery

Reattach the negative battery terminal and ensure it is tightened securely.
