Need A Tune Up? Change Your Spark Plugs At Home

If you've noticed that your car is running a bit hesitant or that it's been having a rough start when you turn on the ignition, it may be time to replace your spark plugs. Clean spark plugs can improve your car's overall performance and can help you get better gas mileage per gallon. Here are the steps you'll need to take if you've decided to replace your spark plugs on your own at home.

Preparation

Before you begin, make sure you've got enough room to work. Gather up the tools you'll need including the new replacement plugs, a pair of needle-nose pliers, a ratchet and socket set, and a few rags to help you clean up. It's always a good idea to wear gloves when working on your vehicle to prevent any cuts or injuries. You will also need a spark plug puller tool, swivel socket, gap gauge, and a torque wrench. Open the hood and clear your engine of any leaves and debris. Make sure the ignition coils are as clean as possible so that nothing falls into the engine's cylinders. Compressed air can help you blast out any excess dirt or gunk.

Remove The Coil And Plugs

First, you will need to twist the ignition coil at about a quarter turn to break the o-ring seal loose; then just pull it up and out. Make sure you disconnect the ignition coil's electrical connector. You can do this by pushing down or pulling up the tab. Now you can take out the entire engine coil and its attached assembly. Most come with a rubber boot and a spring that should be easily removed along with the coil. Use your pliers if you need extra help getting it out. Blow extra debris from your spark plugs before you remove them, and then, using your swivel socket, begin unscrewing the spark plug. Remove the plugs one at a time and put them to the side.

Replace The Plugs

In order to ensure that the new plugs are installed correctly, you must use the correct torque. Be cautious to use the correct specifications for your torque wrench to avoid injury. If you don't apply enough torque it could damage the threads, and if you apply too much it could bend the spark plug. Take your time to ensure that each spark plug is installed snugly with just the right amount of pressure. Once all plugs have been replaced, lube each of the spark plug boots with a special grease designed for plugs. You can find this grease at most auto parts stores. The grease helps to prevent engine misfires, and it will also make changing your spark plugs and boots easier in the future. Now, reinstall the ignition coil and you will have a better running vehicle with a brand new set of spark plugs.
