Solution

1. Preparation

Gather tools and parts needed for the replacement.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down before starting the work.

2. Remove Engine Cover

Use a socket set to remove the screws securing the engine cover.
Carefully lift the engine cover off and set it aside.

3. Access Spark Plugs

Locate the ignition coils on top of the engine.
Disconnect the electrical connectors from each ignition coil.
Remove the bolts securing the ignition coils using a socket wrench.

4. Remove Old Spark Plugs

Using a spark plug socket and ratchet, carefully unscrew each spark plug from the cylinder head.
Inspect the old spark plugs for wear and carbon buildup.

5. Install New Spark Plugs

Check the gap of the new spark plugs using a feeler gauge; adjust as necessary to meet manufacturer specifications (typically around 0.032 to 0.036 inches).
Apply a small amount of anti-seize lubricant to the threads of the new spark plugs.
Hand-tighten each spark plug into the cylinder head, then use a torque wrench to tighten them to the manufacturer’s specified torque (usually around 15-20 lb-ft).

6. Reinstall Ignition Coils

Reattach each ignition coil over the new spark plugs and secure them with the bolts.
Reconnect the electrical connectors to each ignition coil.

7. Reattach Engine Cover

Position the engine cover back on the engine and secure it with the previously removed screws.

8. Reconnect Battery

Reconnect the negative battery terminal and ensure it is secured.
