    Steps to Change Spark Plugs in a 2002 Nissan Xterra

    1. Make sure the engine is cool before starting the spark plug replacement process.

    3. Remove the spark plug wire or ignition coil from the first spark plug by gently pulling it straight out.
    4. Using the appropriate spark plug socket and a ratchet or spark plug wrench, loosen and remove the old spark plug by turning it counterclockwise.
    5. Inspect the old spark plug for any signs of damage or wear. If necessary, replace it with a new spark plug of the same type and heat range.
    6. Apply a small amount of anti-seize compound to the threads of the new spark plug to prevent it from seizing in the cylinder head.
    7. Insert the new spark plug into the spark plug socket and carefully thread it into the cylinder head by hand. Make sure not to cross-thread the spark plug.
    8. Tighten the spark plug with the spark plug socket and ratchet or spark plug wrench. Be careful not to overtighten, as this can damage the spark plug or cylinder head.
    9. Reinstall the spark plug wire or ignition coil onto the new spark plug.
    10. Repeat the above steps for each remaining spark plug.

    By following these steps and using the correct spark plug socket size, you can successfully change the spark plugs in your 2002 Nissan Xterra. Regularly replacing spark plugs can help maintain the performance and fuel efficiency of your vehicle.
