Change Your Own Spark Plugs and Spark Plug Wires

Changing your cars spark plugs may seem like a really intimidating task, but it’s not as complicated as you might think. Almost anyone can change spark plugs with little or no problem and you only need a couple of tools.

Over time spark plugs become covered with carbon deposits, these deposits look like black soot. Carbon can cause your car to lose the power it once had, misfire and can greatly increase gas consumption.

There are some car repairs that are better left to a professional, but there are many things that you can do yourself to save on the costly expense of garage maintenance.

You should never try to work on your car while the engine is hot, especially when your working on anything that is electrical. No matter how careful you are one little slip could result in a serious burn.

A ratchet and a socket are the only tools you will really need, but you can buy a special tool to remove the plugs wires. You don’t really need a tool to remove the wires as long as your careful and don’t pull on the wire itself.

The socket will need to be a deep one, there are sockets especially for spark plugs. It will either be a 13/16 or 5/8, depending on the size of plugs needed for your car.

Just concentrate on one spark plug at a time, never remove all of the wires at once. The spark plug wires have to be in a certain order to each cylinder of your motor, if they’re put back on the wrong plug your car may not start at all.

When you pull the plug wires off make sure to hold the boot of the wire. The boot is the part closest to the plug where it is the thickest, pulling on the wires can break or damage them.

Once you’ve gotten the wire off look around the plug to see if there’s any dirt or debris. You want to be very careful to not let anything fall down inside the motor. If there is anything around the plug you can use a small brush to sweep it out.

After you’ve got it cleaned use the ratchet to remove the plug, you will need to turn it counter clockwise to remove it. Insert the new plug into the hole taking care to keep it straight with the slant of the hole.

Twist the plug in with your fingers as far as you can and then use the ratchet to tighten it. The spark plugs need to be tight, but if you tighten them to much they can break. Once you’ve got the new spark plug in place all that’s left to do is to replace the spark plug wire.

Then just repeat the same steps until you’ve changed all of the plugs. You can of course, just change the spark plugs. But, if your plugs are getting old and worn out then chances are your wires need replaced to.

If you’re changing both the spark plugs and the spark plug wires, you can easily change both at the same time. Just remove the wire from the spark plug and follow it to the back of the motor, pull it loose and replace it with the new wire. Just remember to only do one at a time!

Having your car worked on by a professional is usually pretty expensive. Even a small job such as changing the spark plugs and spark plug wires can cost quite a bit. You can save a lot of money just by doing some of the simpler jobs yourself!
