Steps to Change the Spark Plug

  1. Ensure the engine is cool to prevent burns. Disconnect the spark plug wire by pulling on the boot, not the wire itself, to avoid damage.
  2. Use the spark plug socket and ratchet wrench to remove the old spark plug. Turn counterclockwise to loosen.
  3. Inspect the old spark plug for signs of wear or damage. This can provide insight into the engine's condition.
  4. Apply a small amount of anti-seize compound to the threads of the new spark plug if desired. This helps prevent the plug from seizing in the cylinder head.
  5. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten to the manufacturer's specifications.
  6. Reconnect the spark plug wire, ensuring it is securely attached to the new spark plug.
