Steps to Change the Spark Plug
- Ensure Safety: Make sure 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 Spark Plug Gap: Before installing the new spark plug, use a gap tool to ensure the gap is set to the specifications in your owner's manual. This is crucial for proper engine performance.
- Install the New Spark Plug: If desired, apply a small amount of anti-seize compound to the threads of the new spark plug. Carefully screw it into the engine by hand to avoid cross-threading, then tighten with the socket wrench. 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.
