If you work on your car yourself, it is no surprise that there are things that tend to go wrong. One of these things is when you break engine block bolts accidentally.
Engines are a very important part of your vehicle. If it isn’t properly maintained or in top shape, the vehicle doesn’t perform well.
Broken engine block bolts aren’t the worst problem you can have. It is relatively easy to remove them from your engine block.
1. Spring-loaded Center Punch
One good method to remove the broken bolt is the spring-loaded center punch. It may need a couple of tools to perform.
You want to do the first drill on the center of the bolt. You should use a hardened drill bit for this step.
Using the center punch, look for a grip on the bolt. This is to prevent your drill from wandering.
Then, you can increase the size of the drill bit. Remember to drill slowly and take your time to be able to get the bolt out in one piece.
You can insert and move around a magnetic screwdriver where you drilled your hole from time to time. This is to get any metal particles that the drilling may leave behind.
After completing these steps, you can use a screw extractor or a mole grip to remove the broken bolt. This step should be done as carefully as possible.
Another method you can do is by welding the broken bolt. You need a couple of tools for this one as well.
The first thing to do is ensure that the broken bolt area is well sanitized. It will make the welding process stick a little better.
Next, you will need a washer or nut with the same inside diameter as the broken bolt. The diameter is important because it needs to be a snug fit to the bolt.
Then you can start welding the nut to the broken bolt. Once you see that it is secure, you can begin to try removing the bolt.
Remember to do this carefully to prevent further weld or bolt breaking.
3. Engine Block
The engine block is the mainframe of the engine to which all the pistons and components are attached. Other parts found here are the intake and exhaust passages, crankcases, coolant passages, and other inner components.
Frequently Asked Questions
