How to Remove Broken Head Bolt from Engine Block
Imagine losing your car keys just as you're running late for an important meeting. The frustration and inconvenience are palpable. Removing a broken head bolt from an engine block is similar – it can be a daunting task that grinds your project to a halt. But fret not! With the right tools, techniques, and a dash of patience, you can conquer this challenge and get your engine running smoothly again.
Understanding the Dilemma
Broken head bolts are a common headache for mechanics and DIY enthusiasts alike. They can snap due to excessive torque, wear and tear, or corrosion. Removing them can be a nightmare, especially if they're flush with the engine block's surface. Without proper extraction, you risk damaging the engine beyond repair.
Step-by-Step Removal Guide
- Safety First: Wear safety glasses and gloves. Disconnect the battery to prevent electrical shocks.
- Assess the Damage: Determine the extent of the breakage and the location of the bolt. If it's flush with the block, you'll need to drill it out.
- Drill it Out: Use a drill bit smaller than the bolt's diameter and drill straight down into the bolt's center. Avoid drilling too deep or you might damage the engine block.
- Use an Extractor: Insert an extractor tool into the drilled hole and turn it counterclockwise. If the bolt doesn't budge, apply penetrating oil and let it soak for a few hours.
- Heat It Up: If the bolt is still stuck, apply heat to the area using a heat gun or torch. This will expand the bolt and make it easier to remove.
- Pry it Out: Once the bolt is loose, use a crowbar or pry bar to carefully remove it from the block. Be gentle to avoid damaging the threads.
Wrapping Up
Removing a broken head bolt from an engine block can be a challenging task, but with the right tools, techniques, and patience, it's achievable. Remember to assess the damage, drill carefully, use an extractor, apply heat when necessary, and pry the bolt out gently. By following these steps, you can restore your engine to its former glory and get back on the road with confidence.
How to Remove a Broken Head Bolt from an Engine Block
Introduction
Broken head bolts are a common problem for engines, and they can be a real pain to remove. The good news is that it is possible to remove a broken head bolt yourself with the right tools and techniques. Here is a step-by-step guide on how to remove a broken head bolt from an engine block.
Safety First
Before you begin, it is important to make sure that you are taking the proper safety precautions. Wear safety glasses and gloves, and work in a well-ventilated area. Disconnect the battery and allow the engine to cool before beginning.
Determine the Broken Head Bolt Location
The first step is to determine which head bolt is broken. This can be done by visually inspecting the head bolts or by using a wrench to try to loosen them. If a bolt is broken, it will not loosen.
Remove the Surrounding Head Bolts
Once you have identified the broken head bolt, you need to remove the surrounding head bolts. This will make it easier to access the broken bolt and remove it. Be careful not to overtighten the remaining head bolts.

Drill a Hole in the Broken Head Bolt
Using a drill, drill a small hole in the center of the broken head bolt. This will help to create a starting point for the EZ-Out or other bolt removal tool.
EZ-Out
The EZ-Out is a type of bolt removal tool that is specifically designed to remove broken bolts. The EZ-Out is a tapered tool that is screwed into the drilled hole. As the EZ-Out is tightened, it will grip the broken bolt and allow you to remove it.
Reverse Drill Bit
Another option for removing a broken head bolt is to use a reverse drill bit. A reverse drill bit is a specially designed drill bit that is used to remove broken bolts. The reverse drill bit will drill in a counterclockwise direction, which will help to loosen the broken bolt.
Penetrating Oil
If the broken head bolt is still not coming out, you can try using a penetrating oil such as WD-40 or Liquid Wrench. Spray the penetrating oil on the broken bolt and let it sit for a few minutes. The penetrating oil will help to loosen the rusted bolts.
Heat
Another option for removing a broken head bolt is to use heat. Apply heat to the broken bolt using a torch or heat gun. The heat will help to expand the broken bolt and make it easier to remove.
Caution!
It is important to use caution when using heat to remove a broken head bolt. Do not overheat the bolt, as this could damage the engine block.
Conclusion
Removing a broken head bolt from an engine block can be a challenging task, but it is possible with the right tools and techniques. By following these steps, you can safely and effectively remove a broken head bolt and get your engine running again.
