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 and ratchet wrench to carefully unscrew the old spark plug. Turn counterclockwise until it is free.
- Check the Spark Plug Gap: Use the gap tool to measure the gap on the new spark plug. Adjust it to the specifications found in your owner's manual if necessary.
- Apply Anti-Seize Compound: Lightly coat the threads of the new spark plug with anti-seize compound to prevent it from seizing in the cylinder head.
- Install the New Spark Plug: Carefully thread the new spark plug into the cylinder head by hand to avoid cross-threading. Once hand-tight, use the spark plug socket and ratchet to tighten it securely, but do not over-tighten.
- Reconnect the Spark Plug Wire: Push the spark plug wire boot onto the new spark plug until it clicks into place.
