How to take a broken spark plug out?


Taking out a broken spark plug can be a daunting task, but with the right tools and techniques, it can be done safely and effectively. In this article, we will discuss the step-by-step process of removing a broken spark plug and offer tips to make the job easier.

Gather the necessary materials

Before starting the removal process, it is essential to have the right tools and materials on hand. Here are the materials you will need:

Materials used:
– Porcelain bridges or porcelain pullers
– Needle-nose pliers
– Penetrating oil
– Socket wrench set
– Spark plug socket
– Extension bar
– Ratchet handle
– Rubber hose
– Safety glasses
– Work gloves

Inspect the spark plug

Before attempting to remove the broken spark plug, inspect it to assess the severity of the damage. Look for any signs of cracks, damage to the porcelain, or other issues that may affect the removal process. If the spark plug is severely damaged or broken off deep inside the engine, it may be necessary to seek professional help.

Apply penetrating oil

To make the removal process easier, apply a generous amount of penetrating oil to the area around the spark plug. Allow the oil to penetrate and loosen any rust or debris that may be causing the spark plug to stick.

Remove the broken spark plug

Now that you have prepared the spark plug, it’s time to remove it. Follow these steps:

Step 1: Disconnect the battery – Before starting any work on the engine, disconnect the battery to prevent any accidental sparks.

Step 2: Remove the spark plug wire – Carefully remove the spark plug wire from the spark plug. Use a twisting motion while pulling to avoid damaging the wire.

Step 3: Remove debris – Use compressed air or a small brush to remove any debris or dirt around the spark plug. This will prevent any contaminants from falling into the engine when the broken spark plug is removed.

Step 4: Attach the spark plug socket – Attach the spark plug socket to the extension bar and ratchet handle. Ensure that the socket is the correct size for your spark plug.

Step 5: Loosen the spark plug – Insert the spark plug socket into the spark plug well and turn it counterclockwise to loosen the broken spark plug. Be cautious not to apply excessive force to avoid damaging the threads.

Step 6: Remove the broken spark plug – Once the spark plug is loose, carefully remove it from the engine using the socket, extension bar, and ratchet handle. If the spark plug is stuck, you can try using a rubber hose to create a vacuum and pull it out.


Removing a broken spark plug requires patience, the right tools, and proper technique. By following the steps outlined in this article, you can safely and effectively remove a broken spark plug from your engine. Remember to take your time and exercise caution throughout the process to avoid causing further damage.
