Wondering why your vehicle is having troubles while starting? Your gut instinct may say it’s the battery. However, that might not always be the case. There might be another culprit to blame.
Spark plugs create a spark of electricity that ignites fuel and drives a car’s pistons, ultimately starting the car. With regular wear and tear, spark plugs tend to burn out
Let’s see how we can replace spark plugs.
- Gather all the tools and wires that you may need for the procedure. It is a good practice to disconnect the positive terminal on your battery when working on anything electrical.
- Thoroughly clean the area around your spark plugs. You can use compressed air to blow the area clean, or a cleaner/degreaser spray and shop towels to loosen and remove any grime around the spark plug. Be sure to wear eye protection while doing so.
- Now is the time to start the actual replacement process. Keep everything orderly by removing a single spark plug wire from one spark plug at a time. This prevents reconnecting the wrong wire to the wrong plug when it’s time to button everything back up.
- Fit the necessary combination of extensions and swivels to the spark-plug socket to comfortably fit the tool to the spark plug.
- Once the spark plug is out, take the new spark plug and use the spark plug gap tool to check that there is a proper gap between the outer (hook-shaped) ground electrode and the center electrode. If any adjustment is needed, gently open or close the gap until the tool just fits at the correct gap.
- Now, carefully insert the plug into the open hole by hand. Tighten the plug down with the spark plug socket.
- With the spark plug securely re-installed, reattach the plug wire by twisting slightly as you push the boot back down onto the exposed tip of the plug until you hear and feel a firm click.
Don’t forget to mark down the vehicle’s current mileage in your maintenance notebook, so you’ll know when you need to change your spark plugs again. And you’re done!
