    Steps to Replace Spark Plugs in a 2002 Mazda Protege

    1. Start by ensuring the engine is cool and the ignition is turned off.
    2. Locate the spark plug wires or ignition coils, depending on your engine type. They are typically connected to the top of the engine.
    3. Remove the spark plug wire or ignition coil from the first spark plug by gently pulling it straight out. Be careful not to damage the wire or coil.
    4. Using the 16mm spark plug socket, attach it to a ratchet or extension and carefully loosen the spark plug by turning it counterclockwise.
    5. Once the spark plug is loose, continue turning it by hand until it can be completely removed from the engine.
    6. Inspect the old spark plug for any signs of damage or wear. If necessary, replace it with a new spark plug of the same size and type.
    7. Apply a small amount of anti-seize compound to the threads of the new spark plug to prevent it from seizing in the engine.
    8. Insert the new spark plug into the engine and tighten it by hand until it is snug.
    9. Using the spark plug socket and ratchet or extension, tighten the spark plug an additional 1/16 to 1/8 of a turn.
    10. Reattach the spark plug wire or ignition coil to the spark plug.
    11. Repeat the above steps for each remaining spark plug.

    By following these steps and using the correct 16mm spark plug socket, you can easily replace the spark plugs in your 2002 Mazda Protege. Regularly replacing spark plugs can help maintain engine performance and fuel efficiency. If you have any further questions or concerns, consult your vehicle’s owner manual or contact a professional mechanic.
