Solution

1. Preparation

Tools Required: Spark plug socket, ratchet, torque wrench, gapping tool, extension bar, and a vacuum or compressed air.
Disconnect the negative battery terminal to prevent electrical shorts while working.
Ensure the engine is completely cool before starting the procedure.

2. Remove Engine Cover

Locate the fasteners securing the engine cover (typically bolts or clips).
Use the appropriate socket or tool to remove the fasteners.
Carefully lift off the engine cover and set it aside.

3. Access Spark Plugs

Identify the spark plug wires or ignition coils on the engine.
If equipped with ignition coils, disconnect the electrical connector from each coil.
Remove the bolts securing the ignition coils using the socket and ratchet, then gently pull them out to access the spark plugs.

4. Remove Old Spark Plugs

Before removing the spark plugs, use a vacuum or compressed air to clean around the spark plug area to prevent debris from entering the cylinder.
Use a spark plug socket and ratchet to carefully unscrew each spark plug from the cylinder head.
Inspect the old spark plugs for signs of wear or damage.

5. Install New Spark Plugs

Check the gap on the new spark plugs using a gapping tool, adjusting as necessary to meet manufacturer specifications.
Apply a small amount of anti-seize lubricant to the threads of the new spark plugs to ensure easy future removal.
Carefully thread each new spark plug into the cylinder head by hand to avoid cross-threading, then tighten them to the specified torque using a torque wrench.

6. Reinstall Ignition Coils and Engine Cover

Reinsert the ignition coils and secure them with bolts, ensuring they are tight.
Reconnect the electrical connectors to each ignition coil.
Replace the engine cover, securing it with the fasteners removed earlier.
Reconnect the negative battery terminal.
