Removing Your Old Spark Plugs the Right Way


The first step in changing your spark plugs would be to remove the old ones. To prevent turning this task into an all-weekend project, remove one spark plug at a time, inspect it, wash it, and – if it’s salvageable – gap it. Then replace it before you decide to move on to the following spark connect cylinder sequence order.

To maintain the proper firing order, each spark-plug wire must range from the spark source for the proper spark plug. Therefore, only remove the wire from a single plug at any given time, and don’t disconnect both ends of the wire! By doing this, you won’t ever get into trouble – unless a second wire comes off accidentally.

Follow these steps to remove each spark plug:


1Gently grasp a spark plug wire by the boot (the place where it connects for the spark plug), twist it, and pull it straight out.

Never yank about the wire itself (you can harm the wiring). The shiny thing sticking out of your engine block after you get rid of the wire through the spark plug is the terminal of the spark plug. This figure teaches you all the elements of a spark plug, such as the terminal.

2Use a soft, clean rag or a small paintbrush to clean the area where spark plug enters the block.

Additionally you can blow the dirt away by using a soda straw. Cleaning the area keeps loose junk from falling along the hole into the cylinder whenever you remove the plug.

3Place your spark plug socket (the large one with all the rubber lining) over the spark plug; exert some pressure while turning it slightly to be sure that it’s all the way down.

Don’t be afraid to work with some strength. But utilize it in a controlled manner. In the event you bang or jerk things, you can damage them.

4Stick the square end of your ratchet handle into the square hole from the spark plug socket.

Adding a couple of extensions between the handle and the socket may help you move the handle freely from side to side without hitting anything.


5Loosen the spark plug by turning it counterclockwise.

To obtain the proper leverage, place your free hand over the head of your wrench, grasping the head firmly, and pull the handle, hitting it gently using the palm of the hand to get it going, as shown here.

Be sure your socket is securely over the plug and this the ratchet is at the same angle as the plug to avoid stripping the threads about the plug or even in the spark plug hole in the engine head.

You might have some difficulty loosening a spark plug the first time. , and also other junk might have caused the plug to stay in place, particularly when it’s been a long time since it was changed.Grease and sludge If it feels stuck, try a little spray lubricant.

6When the ratchet turns freely, finish the job by removing the ratchet handle and turning the socket manually until the plug is free from your engine.

After you remove the spark plug in the engine, remove the plug through the socket. But don’t go on to the next plug until you’ve gapped and replaced it.
