How to Loosen Tight Bolts on a Car’s Engine

1. Gather Your Tools

• Socket wrench or box wrench
• Impact wrench (optional)
• Penetrating oil
• Hammer
• Chisel
• Heat gun (optional)

2. Prepare the Bolt

• Apply penetrating oil to the bolt and let it soak in for at least 15 minutes.
• Use a hammer and chisel to break any rust or corrosion that may be holding the bolt in place.

3. Use the Right Tool

• Choose a socket wrench or box wrench that fits the bolt snugly.
• If possible, use an impact wrench to provide additional torque.

4. Apply Force

• Position the wrench on the bolt and apply downward pressure.
• Turn the wrench slowly and steadily, applying increasing force as needed.

5. Use a Breaker Bar

• If you’re having difficulty loosening the bolt, use a breaker bar to provide additional leverage.
• Insert the wrench into the breaker bar and apply force.

6. Apply Heat

• As a last resort, you can try using a heat gun to heat the bolt.
• Heat can expand the bolt and make it easier to loosen.
• Caution: Do not overheat the bolt, as this can damage the engine.

7. Cut the Bolt

• If all else fails, you may need to cut the bolt off.
• Use a hacksaw or angle grinder to cut the bolt as close to the engine as possible.
• Caution: Be careful not to damage any other components when cutting.

Additional Tips

• Always wear safety glasses and gloves when working on your car.
• If you’re not comfortable loosening the bolts yourself, consult with a mechanic.
• Tightening bolts to the correct torque is important to prevent them from loosening or breaking.
• Regularly inspect your car’s bolts and nuts for signs of corrosion or damage.
