Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to avoid any electrical shorts.
Allow the engine to cool down completely before beginning work.

2. Remove Engine Cover (if applicable)

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

3. Access the Spark Plugs

Tools Required: Ratchet and extension
Locate the ignition coils on top of the engine, typically there will be one coil for each spark plug.
Disconnect the electrical connectors from each ignition coil by pressing the tab and pulling them off.

4. Remove Ignition Coils

Tools Required: Ratchet with appropriate socket
Unbolt the ignition coils using the ratchet and socket.
Gently pull each ignition coil out of its respective spark plug hole.

5. Remove Old Spark Plugs

Tools Required: Spark plug socket and ratchet
Use the spark plug socket to carefully unscrew the old spark plugs from the engine.
Inspect the old spark plugs for condition and compare them to new ones to confirm they need replacement.

6. Install New Spark Plugs

Tools Required: Spark plug socket and torque wrench
Apply a small amount of anti-seize compound on the threads of the new spark plugs.
Hand-tighten each new spark plug into the hole and then use a torque wrench to tighten to the manufacturer’s specified torque (typically around 13-15 lb-ft).

7. Reinstall Ignition Coils

Tools Required: Ratchet and socket
Insert each ignition coil back into position over its respective spark plug.
Re-bolt each ignition coil securely.
Reconnect the electrical connectors to each ignition coil.

8. Reinstall Engine Cover (if applicable)

Place the engine cover back onto the engine and secure it with the previously removed screws or bolts.

9. Reconnect Battery

Reconnect the negative terminal of the battery.
