The exhaust manifolds keep the car engine cool. Exhaust manifolds play the main role in emitting the engine hit gasses. The exhaust connects with the manifold by bolts.
You may desire to remove the exhaust from the manifold for repair. you have to remove the bolts first to remove the exhaust. But people don’t often remove the exhaust from manifolds. That’s why the bolts get rust. And when people try to remove the bolts, they break them. So, how to remove exhaust manifold bolts?
It will be too hard for you to remove the bolts without breaking if you don’t know the proper steps. Our team researched the bolts removal problem. We have found an effective way to remove exhaust manifold bolts without breaking.
Why Bolt Breaks When We Try To Remove Them From Exhaust Manifold (4 Reasons)
1.Old And Rusty Bolts
Normally, we remove exhaust manifold bolts after a long time. That’s why the exhaust manifold bolts get rusty. Because of that, the patch of the bolts gets diminished. When we try hard to remove those bolts, they break.
2.Broken Bolts
For rust, the exhaust manifold bolts crack. We often see broken bolts when we desire to remove them. It is stressful to remove broken bolts if you don’t know the exact method. Rust makes complexity to remove broken bolts. Inexperienced persons can’t remove the bolts properly because of this reason.
3.Not Knowing The Proper Steps
Inexperienced people don’t know how to remove exhaust manifold bolts properly. That’s why they break the bolts when they try to remove bolts.
4.Incautiousness
Sometimes, experience people break bolts when they try to remove them from the exhaust manifold. It occurs for incautiousness. You have to be patient and careful to remove old and rusty bolts from the exhaust manifold.
Way To Remove Exhaust Manifold Bolts Without Breaking
The simple and effective way to remove bolts without breaking is given below step by step.
Step 1: Remove The Tire
You have to make some space to remove the exhaust manifold. Remove the wheel first. Then remove the tire and inner fender liner.
Step 2: Figure Out What Parts Will Need
Inspect bolts, and figure out what you will need to remove them. Then look at the exhaust and note down what parts are spoilt and missing. It’s better to inspect the exhaust before removing it.
Step 3: Use A Penetrating Spray
Penetrating spray helps to free rusty bolts. You can use this on any tight space to free rusty mechanical parts. You will find many penetrating sprays in markets. Get a good one.
Step 4: Leave It For Some Minutes
Use the spray on every bolt. After spraying penetrating spray on rusty bolts, leave them for some minutes. The bolts will need some time to react. After few minutes, you will see the bolts are loose enough to remove them.
Step 5: Use The Right Wrench
Pick the right wrench according to the bolt’s head. Sometimes people don’t pick the right wrench. As a result, they can’t remove exhaust manifold bolts without breaking.
Step 6: Spin The Wrench Anti-clockwise
You may know how to remove a bolt with a wrench. You have to spin the wrench anti-clockwise. But, be careful. Don’t apply too much force the first time. Slowly remove bolts one by one.
How To Remove A Broken Bolt
We see two types of broken bolts. One is broken from the middle and the other one from the top. You have to use two different methods to remove them.
When Broken From The Middle
Step 1: Drill On The Bolt
Drill on the middle of the bolt and make some space. Try to drill at a 90-degree angle. And don’t drill with a too big or too small drill bit. Chose the drill bit according to the Torx socket size.
Step 2: Put A Torx Socket
Put a Torx socket into the bolt. Take a wrench. And use the Torx socket head as the bolt head. Then remove the bolt.
When Broken From The Head
Step 1: Take A Screw
Take a screw according to the bolt size.
Step 2: Weld The Screw On The Bolt
Place the screw at the top of the broken bolt. And carefully weld the screw with the bolt. Leave them for few minutes to connect properly.
Step 3: Take A Right Wrench
Take the wrench according to the screw. And use the screw as the bolt head. Then slowly remove the bolt.
Final Thoughts
It’s quite hard to remove exhaust manifold bolts without breaking. You have to be careful and patient to remove the bolts without breaking. You can remove exhaust manifold bolts without breaking if you know the exact method.
We tried to show an easy and useful method to remove the bolts without breaking. In addition, we showed two methods to remove a broken bolt. We hope those methods help you to remove bolts without breaking. I hope now you know how to remove exhaust manifold bolts.
