Solution

1. Preparation

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

2. Remove Engine Cover (if applicable)

Remove any screws or clips holding the engine cover in place.
Carefully lift off the engine cover and set it aside.

3. Remove Old Spark Plugs

Using a socket wrench with an appropriate size spark plug socket, carefully loosen and remove each spark plug.
Inspect the removed spark plugs for wear patterns and damage.

4. Install New Spark Plugs

Apply a small amount of anti-seize compound to the threads of the new spark plugs (if recommended).
Hand-tighten the new spark plugs into the cylinder head.
Use a torque wrench to tighten the spark plugs to the manufacturer’s specification (typically around 13-20 lb-ft, but verify with a repair manual).

5. Reassemble Components

Reattach the ignition coils or wires to the new spark plugs.
Replace the engine cover and secure it with screws or clips.
Reconnect the negative battery terminal.

6. Test Engine Function

Start the engine and let it idle to ensure smooth operation.
Check for any engine warning lights on the dashboard.
