How to Replace your Spark Plugs

Spark plugs help create the energy that power most gas powered cars. It ignites a vehicle's fuel by channeling the electrical current by essentially setting off small controlled explosions. Of course over time the spark plugs will begin to burn out and will no longer work. Once that happens you know it’s time to get them replaced. The question now is how can it be done.

The job is relatively easy to get done. However, it depends on the type of vehicle you have. Certain models may be difficult to work with because of having to remove portions from your engine to reach your spark plugs. If that’s your case it might be best to take it to a mechanic to fix to avoid any possible problems. But if you have easy access to the rear bank of the engine you can easily continue doing this job yourself.

Step 1: Locate your Spark Plugs

If you’re not sure spark plugs are made up of about 4-8 wires that all lead to different points of an engine. Depending on the type of vehicle you have they will be located in different spots. It would be best to refer to your vehicle's owner manual to easily locate them.

Once you’ve located the spark plugs it would be best to let the car cool down before attempting to remove them. This would be a good time to prepare the tools you’ll need for this job. Tools include a ratchet socket drive wrench, an extension bar, spark plug socket and a spark gap gauge.

Step 2: Removing the Spark Plugs

It’s now time to carefully remove each of your old spark plugs. You have to be sure you don’t pull hard from the wrong spot on the plug. It’s best to keep your grip close to the bottom while gently pulling the plug out. You’ll then want to fit your socket wrench with the extension and use it slowly to remove the spark plug from its placement.

Once all the plugs have been properly removed it would be wise to measure the gap of the spark plug. Doing this will allow you to see if some of the spark plugs you removed can be potentially reused with an adjustable gap plug.

Step 3: Get the Right Replacement Spark Plugs

Finding the proper replacement shouldn’t be tough but it’s definitely something you want to take your time with. You don’t want to rush ahead and purchase the wrong parts or else you’ll have nothing but a headache. The best thing you can do would be to look into your car's owner manual or contact your local auto parts store.

Step 4: Installing the New Spark Plugs

Now that you have your new spark plugs it's time to begin installing them into your engine. Before going ahead though now would be a good time to do some cleaning. It would be wise to check up on some wires to make sure everything is in good shape and that everything is clean.

We also recommend that you lubricate the spark plugs before you insert them. Doing this will help prevent any type of reaction with aluminum engines. When you’re done with that it's time to go ahead with your ratchet and insert the new spark plugs, tightening them into place. Be sure you don’t tighten them too much as it might damage the head of the plug. Make sure you work gently and insert each plug with caution. As soon as you're done you’re all set to go.

Although the process might sound scary, it's actually a lot simpler when you go in. It just takes some time ad care but doing this work yourself will help save you money in the long run.
