How to Tighten Crankshaft Pulley Bolt Without an Impact Gun
The crankshaft pulley bolt is a critical fastener that holds the crankshaft pulley in place. It’s important to make sure this bolt is properly tightened, as a loose pulley can cause serious damage to your engine.
In this article, we’ll show you how to tighten the crankshaft pulley bolt without an impact gun. We’ll also provide some tips on how to prevent the bolt from coming loose in the future.
What you’ll need:
- Wrench
- Socket
- Extension bar
- Penetrating oil
- Torque wrench
Step 1: Locate the crankshaft pulley bolt
The crankshaft pulley bolt is located on the front of the engine, near the bottom. It’s a large bolt with a hex head.
Step 2: Spray the bolt with penetrating oil
Before you try to tighten the bolt, spray it with penetrating oil. This will help to loosen any rust or corrosion that may be preventing the bolt from turning.
Step 3: Loosen the bolt
Use a wrench to loosen the bolt. You may need to use an extension bar to reach the bolt.
Step 4: Tighten the bolt to the specified torque
Once the bolt is loose, use a torque wrench to tighten it to the specified torque. The torque specification for this bolt is usually between 30 and 40 ft-lbs.
Step 5: Apply thread sealant
After you’ve tightened the bolt, apply a small amount of thread sealant to the threads. This will help to prevent the bolt from coming loose in the future.
Step 6: Reinstall the pulley
Once the bolt is tightened, reinstall the pulley. Make sure the pulley is properly aligned with the crankshaft.
Tips for preventing the bolt from coming loose:
- Use a high-quality thread sealant.
- Make sure the bolt is tightened to the specified torque.
- Inspect the bolt regularly for signs of wear or damage.
- Replace the bolt if it’s damaged or if the torque has loosened.
By following these tips, you can help to ensure that the crankshaft pulley bolt stays tight and your engine stays safe.

How do I tighten a crankshaft pulley bolt without an impact gun?
There are a few ways to tighten a crankshaft pulley bolt without an impact gun. One way is to use a breaker bar and a socket. Another way is to use a torque wrench.
To use a breaker bar and a socket, follow these steps:
1. Locate the crankshaft pulley bolt. The crankshaft pulley bolt is usually located on the front of the engine, near the center of the crankshaft.
2. Put the breaker bar in the socket. The socket should fit snugly over the crankshaft pulley bolt.
3. Place the other end of the breaker bar against a solid object. This could be a piece of wood or a heavy metal object.
4. Turn the breaker bar clockwise to tighten the crankshaft pulley bolt. Apply firm, steady pressure as you turn the breaker bar.
To use a torque wrench, follow these steps:
1. Locate the crankshaft pulley bolt. The crankshaft pulley bolt is usually located on the front of the engine, near the center of the crankshaft.
2. Attach the torque wrench to the crankshaft pulley bolt. The torque wrench should fit snugly over the crankshaft pulley bolt.
3. Turn the torque wrench clockwise to tighten the crankshaft pulley bolt. Turn the torque wrench until it reaches the specified torque setting.
What is the torque setting for a crankshaft pulley bolt?
The torque setting for a crankshaft pulley bolt varies depending on the make and model of your vehicle. The torque setting can usually be found in your vehicle’s owner’s manual.
What can I do if I can’t tighten the crankshaft pulley bolt?
If you can’t tighten the crankshaft pulley bolt, there are a few things you can try.
- Make sure that you are using the correct size socket and breaker bar. The socket should fit snugly over the crankshaft pulley bolt, and the breaker bar should be long enough to provide leverage.
- Apply firm, steady pressure as you turn the breaker bar. Don’t jerk the breaker bar or use excessive force.
- If you are still having trouble, you can try using a cheater bar. A cheater bar is a piece of metal that you can attach to the end of the breaker bar to provide additional leverage.
What should I do if I tighten the crankshaft pulley bolt too much?
If you tighten the crankshaft pulley bolt too much, you could damage the bolt or the crankshaft. If you think you have tightened the bolt too much, you should loosen it and try again.
How often should I tighten the crankshaft pulley bolt?
The crankshaft pulley bolt should only be tightened when it is necessary to remove the crankshaft pulley. This could be for a number of reasons, such as replacing the crankshaft pulley, the crankshaft, or the timing belt.
