Steps to Change the Spark Plug

  2. Remove the Spark Plug Cap: Gently pull the spark plug cap off the spark plug. Be careful not to damage the cap or the wire.
  3. Remove the Old Spark Plug: Use the spark plug socket wrench and ratchet to unscrew the old spark plug. Turn counterclockwise until it is free.
  4. Inspect the Old Spark Plug: Check the old spark plug for signs of wear or damage. This can provide insight into the engine's condition.
  5. Install the New Spark Plug: Insert the new spark plug into the socket and carefully thread it into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten it to the manufacturer's specifications (typically 18-22 ft-lbs).
