Solution

1. Preparation

Tools Required: Socket set, torque wrench, spark plug gap tool, dielectric grease, anti-seize compound.
Disconnect the negative battery terminal to prevent electrical shock.
Allow the engine to cool if it has been running.

2. Remove Engine Cover (if applicable)

Tools Required: Socket set.
Remove any screws or bolts securing the engine cover using the appropriate socket.
Carefully lift the engine cover off and set it aside.

3. Remove Old Spark Plugs

Tools Required: Spark plug socket, ratchet, extension.
Locate the spark plug wires or coils and carefully disconnect them.
- For plug wires, gently twist and pull to avoid damage.
- For coil packs, remove the retaining screws and lift off the coil.
Use the spark plug socket and ratchet to unscrew the old spark plugs from the engine block.
Inspect the removed spark plugs for signs of wear or damage.

4. Install New Spark Plugs

Apply a small amount of anti-seize compound to the threads of the new spark plugs.
Check the gap on the new spark plugs and adjust to manufacturer specifications using the spark plug gap tool.
Carefully insert the new spark plugs into their respective holes and hand-tighten them to avoid cross-threading.
Use the torque wrench to tighten the spark plugs to the manufacturer's specified torque (typically around 13-15 lb-ft).

5. Reconnect Components

Reattach the spark plug wires or coil packs ensuring they click into place securely.
If applicable, reinstall the engine cover and secure it with the original screws or bolts.

6. Reconnect Battery

Reconnect the negative battery terminal.
Start the engine and listen for smooth operation.
