Tips for DIY Vehicle Spark Plug Replacement

Spark plugs are a vital component in most car engines and they will need to be replaced from time to time. The difficulty of this task will vary wildly based on the type of vehicle, yet it still remains a relatively simple DIY job which you can accomplish within a few hours.

Before you get started on any kind of work, you need to be informed regarding the spark plugs and all the information can be found in the vehicle's manual. Here you will learn where the spark plugs are located on your car, how many there are and what you need to do in order to remove them. After you have this information you can then go and purchase the correct spark plugs you need plus any extra tools you might require to get the job done. Afterwards here are the steps to replacing your old spark plugs with new ones.

  • Prepare the vehicle. You will want the car to be parked somewhere with a roof in case it starts raining while you are working. Be warned that you should wait several hours after the engine was on before working on the spark plugs because they get really hot.

  • Find the distributor cables for the spark plugs. These wires are usually red or black in color and they are the same number as the spark plugs. They will also be divided equally on both sides of the engine. The cables will need to be removed, but afterwards will need to be placed back in the same spots so it is best to number them instead of trying to remember which cable goes where. Once this is done, the cables can be removed by twisting and pulling on the caps.
  • Clean the area. While you are here, this is a good opportunity to use compressed air or a simple brush and clear the plugs of dirt, dust and any other debris.
  • Replace old spark plugs. Usually, a socket wrench is all that is needed in order to remove the old spark plugs and fit in the new ones. Make sure not to tighten them too much.
  • Put back the cables. The distributor cables need to be fitted again, making sure to put each one back in its original place.
  • Start the engine. If everything went right, the engine should start now good as new.
