Step-by-Step Guide
Step 1: Preparation
Ensure the engine is cool to prevent burns. Disconnect the spark plug wire by pulling the boot off the plug. Avoid pulling on the wire itself to prevent damage.
Step 2: 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 loose enough to remove by hand. Inspect the old plug for any signs of wear or damage, which can indicate engine issues.
Step 3: Install the New Spark Plug
Apply a small amount of anti-seize compound to the threads of the new spark plug. This will make future removal easier and prevent thread damage. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the torque wrench to tighten the spark plug to the manufacturer's specified torque setting.
Step 4: Reconnect the Spark Plug Wire
Firmly push the spark plug wire boot back onto the new spark plug until you feel it click into place. Ensure the connection is secure to prevent misfires.
