Steps to Change the Spark Plug
- Preparation: 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.
- Remove the Old Spark Plug: Use the spark plug socket wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is free.
- Check the Gap: Use a gap tool to measure the gap on the new spark plug. Refer to your owner's manual for the correct gap measurement. Adjust if necessary.
- Install the New Spark Plug: Apply a small amount of anti-seize compound to the threads of the new spark plug if desired. Carefully screw the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the socket wrench to snug it up, but do not over-tighten.
- Reconnect the Spark Plug Wire: Push the spark plug wire boot back onto the new spark plug until it clicks into place.
