Step-by-Step Guide for Removing Stuck Spark Plugs

To maintain the car’s proper functioning, it is essential to provide it with regular care and maintenance. It not only protects your vehicle from expensive damages but also adds to its durability. Moreover, it also greatly adds to the performance of the car. Therefore, sending the vehicle for professional service once a month is the routine of most car owners.

Regular care and maintenance of the car involve thorough inspection, detection, repairing, and replacing defective parts to ensure stress-free traveling. However, the most important step of this routine is to remove a spark plug that is stuck. It’s crucial to avoid engine ignition problems and protection from accidents.

What is A Spark Plug?

A spark plug is one of the most crucial components of the car engine system. It ignites the spark to start the engine. They need to be replaced after a specific duration to ensure a safe drive and avoid massive problems. Their durability and life span depend on the type and quality. Usually, an iridium spark plug with 100,000 miles life span is more durable than a platinum spark plug with 50,000 mikes lifespan.

What Causes a Spark Plug To Stuck?

Spark plugs are very crucial and sensitive components of the car engine system. They can be easily seized and damaged or stuck. Many reasons can cause a spark plug stuck including;


One of the most common reasons for a stuck plug is fouling. It has two electrodes that receive and supply the spark to perform its job effectively. However, when deposits start building on electrodes they become stuck. This process is known as fouling.


As we mentioned earlier, spark plugs need a spark to ignite the engine. However, when they start missing fire they become stuck. It is crucial to replace such tools ASAP to avoid further damage.


Corrosion is one of the most common reasons for a stuck spark plug. When dust, deposits, and oil start accumulating on electrodes and around the plug is called co-corrosion.

How To Remove A Stuck Spark Plug?

The removal of a spark plug is a simple and easy task that most people can even perform at home safely. However, getting a stuck spark plug out is a tough job that consumes a lot of time. It required a professional approach and tools.

Are you looking for an effective way to get rid of a stuck plug? Or tried various methods but can’t get a spark plug out? Don’t fret, we are here to help you. All you need is to follow these step-by-step instructions carefully.

Tips and Tricks for Dealing with Stuck Spark Plugs

1. Find The Position of the Spark Plug

The very first step is finding the exact location of the spark plug. They may be present in the head, side, and bottom. In the case of side and bottom locations, it’s quite hard to access them and may need a lift.

2. Pull the Wire Off

The next step to remove a stuck plug is pulling its cap and to wire off the plug.

3. Spray Penetrating Oil

Rust or corrosion is the most important cause of a stuck spark plug. Therefore, the next step is spraying a barrel with oil. It will loosen the corrosion and dust present around.

4. Allow Oil Penetration

Oil penetration is crucial to soften the corrosion present around. After spraying the oil, leave it for 20 minutes or half an hour.

5. Tighten The Spark Plug

Before removing the spark plug, tightening it to a specific time frame is essential. You can use a wrench or a screw to move it clockwise and then anticlockwise. It will greatly loosen the corrosion and deposits.

6. Soak With Oil

If you are still facing difficulties in removing a stick then soaking with penetrating oil is the next step. You can leave it overnight to ensure the loosening of the stocking material.

7. Turn the Engine On

The second last step is turning on the car engine and allowing it to warm. It not only helps the oil to penetrate deeply but also loosens the gunk present around the stuck spark plug.

8. Repeat steps 1-4

Repeat steps 1-4 until the damaged or stuck plug is removed completely.


After going through this guide, you are well aware of how to tell if a spark plug is bad, the spark plug extractor, and the right way to remove it safely. Therefore, make sure to replace your stuck, ceased, and broken plug as soon as possible. You can also hire the services of a professional mechanic to ensure the safe and quick removal of a stuck spark plug.
