Solution

1. Preparation

Tools Required: Ratchet and socket set, torque wrench, spark plug gap tool, dielectric grease, compressed air (optional).
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool completely before starting.

2. Remove Engine Cover

Locate and remove any screws or clips securing the engine cover.
Lift the engine cover off carefully and set it aside.

3. Remove Old Spark Plugs

Use the ratchet and socket to loosen and remove the spark plug wires or ignition coils (if applicable).
Carefully remove the spark plug boots, taking care not to damage them.
Using the ratchet and socket, unscrew each spark plug from the cylinder head.

4. Inspect and Prepare New Spark Plugs

Compare the old spark plugs with new ones to ensure proper size and type.
Check and adjust the gap of the new spark plugs to the manufacturer's specifications (typically between 0.028 and 0.032 inches).
Apply a small amount of dielectric grease to the inside of the spark plug boots.

5. Install New Spark Plugs

Carefully thread each new spark plug into the cylinder head by hand to avoid cross-threading.
Use the torque wrench to tighten the spark plugs to the manufacturer's specified torque (usually around 13-15 lb-ft).
Reinstall the spark plug wires or ignition coils, ensuring they are seated properly.

6. Reinstall Engine Cover

Place the engine cover back onto the engine and secure it with screws or clips.

7. Reconnect Battery

Reconnect the negative battery terminal.
