Replacing Your Vehicle’s Ignition Wires & Spark Plugs

For those unfamiliar with what makes your car run, hearing that you have a spark plug issue like a cylinder misfire or a wiring problem is frustrating news. The parts aren’t expensive but, if you don’t know how to do it yourself, you can end up shelling out more than you want to have a professional fix the problem. Good news, changing spark plugs is something you can tackle yourself.

What You Need

As far as supplies, you can choose to get grease to apply to the new spark plugs or ignition wires to make its parts easier to remove next time and a wire pulling tool, but as long as you’re careful you will be fine. However, if you are replacing the spark plugs you will need a socket wrench and an extension that fits snugly around the spark plug. If you aren’t the strongest person, another great tool is a strong friend to help make sure everything is tight.

Replacing the Ignition Wires

Plenty of people have learned the hard way, when it comes to replacing ignition wires it matters which one goes to each cylinder because they go in a specific firing order. Replace one wire at a time or, if you want more room to work with, take good pictures to document which wires go where. The next part is pretty easy, gently ease the plugs from their ports and put the correct replacement wire in its place. Make sure you hear the end boot click into place on the distributor.

Changing the Spark Plugs

Start by removing the old one with the socket wrench. Then, put in the new one. Make sure it is sitting straight in its chamber because if the threading is off the electricity won’t ignite properly. To check this you can put your finger in and if it feels uneven just reinstall it.

  1. I think my husband has learned the hard way about having to replace his spark plug. He tried to leave for work this morning and his car wouldn’t start, so I ended up having to take him. I’m hoping that I’ll be able to take his car into an auto repair service soon. That way I don’t have to drink him to work tomorrow.
