Solution

1. Preparation

Tools Required: Socket set, torque wrench, ratchet, extension bar, spark plug socket, dielectric grease.
Safety Warnings: Disconnect the negative battery terminal before starting work.

2. Access Spark Plugs

Remove the engine cover (if applicable) by unscrewing any bolts or clips.
Locate the spark plug wires or ignition coils on each cylinder.
Carefully disconnect the spark plug wires or remove the ignition coils by unscrewing the mounting bolts.

3. Remove Old Spark Plugs

Use a spark plug socket with an extension to reach the plugs.
Turn counterclockwise to remove each spark plug from the cylinder head.
Inspect each old spark plug for wear, deposits, or damage.

4. Install New Spark Plugs

Apply a small amount of dielectric grease to the threads of the new spark plugs.
Hand-tighten each new spark plug into the cylinder head.
Use a torque wrench to tighten the spark plugs to the manufacturer's specified torque (usually around 13-15 ft-lbs).

5. Reassemble Components

Reconnect the ignition coils or spark plug wires, ensuring they are seated properly.
Replace the engine cover if it was removed, securing it with bolts or clips.
Reconnect the negative battery terminal.
