Steps to Change the Spark Plug

  1. Locate the Spark Plug: The spark plug is located on the engine's top side. Remove any covers or components that may obstruct access.

  3. Remove the Old Spark Plug: Use the spark plug socket and ratchet wrench to unscrew the old spark plug. Turn counterclockwise until it is free.
  4. Prepare the New Spark Plug: If desired, apply a small amount of anti-seize compound to the threads of the new spark plug. This helps prevent seizing in the future.
  5. Install the New Spark Plug: Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten it to the manufacturer's specifications.
  6. Reconnect the Spark Plug Wire: Push the spark plug wire boot onto the new spark plug until it clicks into place.
