Steps to Change the Spark Plug

  2. Remove the Spark Plug Cap: Gently pull the spark plug cap off the plug. Be careful not to damage the wire.
  3. Remove the Old Spark Plug: Use the spark plug socket wrench to turn the plug counterclockwise until it is loose. Remove it from the engine.
  4. Check the New Spark Plug: Before installation, check the gap on the new spark plug using a gap tool. Adjust if necessary to match the specifications in your owner's manual.
  5. Install the New Spark Plug: If desired, apply a small amount of anti-seize compound to the threads of the new plug. Carefully thread 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.
