Tensioner Pulley Bolt Broke off in Engine
If you’re lucky, you may be able to retrieve the broken bolt from the engine. However, more often than not, the tensioner pulley bolt breaks off inside the engine, making it impossible to remove. In this case, you’ll need to replace the entire tensioner pulley assembly.
The tensioner pulley is a vital component of your engine. It’s responsible for maintaining proper belt tension on the accessories driven by the serpentine belt. If the belt becomes too loose, it can slip off the pulleys and cause serious damage to your engine.
Conversely, if the belt is too tight, it can overheat and break. Either way, a failed tensioner pulley can lead to big problems for your engine. If you suspect that your tensioner pulley has failed, or if you find that your serpentine belt has come off its pulleys, don’t delay in getting it fixed.
A broken tensioner pulley bolt can be a real pain to deal with, but it’s nothing compared to the alternative of having major engine damage caused by a loose or broken serpentine belt.

How Do You Remove a Tensioner Pulley Bolt?
Assuming you are referring to a serpentine belt tensioner:
1. Place a wrench on the bolt in the center of the tensioner.
2. Turn the bolt clockwise to release the tension on the belt.
3. Remove the belt from around all of the pulleys except for the one at the tensioner.
4. Hold onto the belt and pull it away from the pulley as you turn the bolt counterclockwise to loosen it completely.
Be careful not to let go of the belt or it will snap back and possibly injure you.
How Do You Remove a Stripped Idler Pulley Bolt?
If you have a stripped idler pulley bolt, there are a few ways that you can remove it. One way is to use a drill and start drilling out the center of the bolt. This will take some time and patience, but eventually, you will be able to get the stripped idler pulley bolt out.
Another way to remove a stripped idler pulley bolt is by using a chisel and hammer. First, find the end of the bolt that is not stripped. Place the chisel on this end and hit it with the hammer until the chisel goes through the head of the bolt.
Then, turn the chisel so that it is flush with the side of the headless Bolt and hit it again with your hammer. The head of the Bolt should now be loose enough for you to remove by hand.
How Do You Remove a Broken Bolt Without an Extractor?

Finally, if all else fails, you can always drill a hole through the head of the bolt and use a screwdriver to remove it.
How Do You Remove a Broken Bolt from an Engine Block?
If you’re lucky, the broken bolt will be sticking out of the engine block far enough that you can use a wrench to remove it. However, if the bolt is flush with the surface or recessed, you’ll need to use a more creative approach. One method is to weld a nut onto the end of the bolt using a MIG welder.
Once the nut is in place, you can use a socket and ratchet to remove the broken bolt. Another option is to drill a hole into the head of the bolt and then use an extractor tool to remove it. Whichever method you choose, make sure that you are careful not to damage the engine block in the process.

If you have a broken tensioner pulley bolt, don’t worry. You can remove it with a few simple steps. First, use a ratchet to loosen the bolt.
Then, use a pair of pliers to remove the pulley from the bolt. Finally, use a hammer to tap the broken bolt out of the hole.
