If you notice that the tensioner arm on your vehicle is binding, sticking, or grinding, you may need to replace the tensioner. This article will explain the symptoms of a failing tensioner and how to replace it.
So, is the tensioner pulley supposed to move?
No, the tensioner pulley is not supposed to move. The tensioner arm should move smoothly and freely. If you notice a binding, sticking or grinding tensioner arm, the tensioner should be replaced.
Let’s dig into it and see if we can figure it out.
What Causes The Tensioner Pulley To Move?
The tensioner pulley is designed to keep the serpentine belt tight and in proper alignment. However, over time the pulley can become worn or damaged, causing it to move and cause the belt to become misaligned. Common causes of pulley problems include a defective belt tensioner, misalignment of a pulley, or defective bearings.

How Can You Tell If The Tensioner Pulley Is Damaged?
If you’re noticing resistance when you try to move the tensioner pulley with a wrench, it could be a sign that the pulley is damaged. Other signs of damage include a grinding or squeaking sound coming from the engine, or an idler pulley that makes noise when it starts to go bad.
If you notice any of these symptoms, it’s important to have the pulley checked out by a professional to avoid further damage to your engine.

What Are The Symptoms Of A Damaged Tensioner Pulley?
If you notice any of the following symptoms, it’s possible that your tensioner pulley is damaged and needs to be replaced:
1. Rust bleed and cracks 2. Pulley bearing wear 3. Pulley wear 4. Tensioner assembly misalignment 5. Tensioner noise 6. Tensioner arm misalignment
If you suspect that your tensioner pulley is damaged, it’s important to have it checked out by a qualified mechanic as soon as possible. Left unchecked, a damaged tensioner pulley can cause serious problems with your car’s engine, including belt slippage and reduced performance.
If you notice any rust bleed, cracks, wear, misalignment, or noise coming from the tensioner pulley, it may be damaged and needs to be replaced.
How Do You Replace A Damaged Tensioner Pulley?
If your tensioner pulley is damaged, you’ll need to replace it to keep your engine running smoothly. Here’s a quick guide on how to do it:
1. First, locate the damaged pulley. You can usually spot it by looking for damage to the bearing or pulley itself.
2. Once you’ve found the damaged pulley, remove it from the engine.
3. To install the new pulley, simply reverse the process. First, attach the new pulley to the engine, then tighten it down.
4. Finally, check the tensioner pulley to make sure it’s moving freely. If it’s not, you may need to adjust the tensioner itself.
With a few simple tools and a replacement pulley, you can easily replace a damaged tensioner pulley. Just be sure to check the tensioner pulley regularly to ensure it’s moving freely and not causing any damage to the engine.

What Are The Consequences Of Not Replacing A Damaged Tensioner Pulley?
If your vehicle has a damaged tensioner pulley, it is important that you do not drive it. If you do, you risk damaging other accessories that are driven by the belt, as well as causing the engine to overheat. In addition, a failed tensioner pulley can cause the serpentine belt to come off entirely, leading to catastrophic engine failure.

How Do You Know If Your Belt Tensioner Pulley Is Bad?
If you’re hearing grinding or squeaking noises coming from your belt, that’s a pretty good indication that your belt tensioner pulley is bad. You may also notice unusual belt wear, or belt-driven accessories like your alternator failing. If you’re experiencing any of these issues, it’s best to have your belt tensioner pulley checked out by a professional to see if it needs to be replaced.
Is The Belt Tensioner Supposed To Spin?
Yes, the belt tensioner is supposed to spin. Every time you replace the serpentine belt, you should check the tensioner to make sure it spins freely. If you hear grinding or the pulley doesn’t spin freely, replace the tensioner.
What Happens If Tensioner Is Loose?
If a timing belt tensioner becomes loose, it can cause the timing belt to become loose as well. This can then lead to the valve timing becoming thrown off, which will in turn lead to engine performance issues. Therefore, if there is any suspicion that the timing belt tensioner may have failed, it is important to check it and replace it if necessary.
How Do I Know If My Tensioner Pulley Is Too Tight?
If your tensioner pulley is too tight, you may notice that your engine belt is slipping or that your engine is making a squealing noise. You may also notice that your engine is running rough or that your car is vibrating. If you notice any of these symptoms, you should have your tensioner pulley checked by a mechanic.
What Are The Possible Reasons For A Belt Tensioner To Wobble At Idle?
The possible reasons for a belt tensioner to wobble at idle are:
1) A defective belt tensioner.
2) Misalignment of a pulley.
3) Defective bearings.
What Are The Symptoms Of A Tensioner Pulley Failure?
The symptoms of a tensioner pulley failure can include rust bleed and cracks, pulley bearing wear, pulley wear, tensioner assembly misalignment, tensioner noise, tensioner arm misalignment, and belt squealing.
FAQs:
- What Is A Serpentine Belt Tensioner Pulley?: A serpentine belt tensioner pulley is a pulley that is used to keep tension on the engine belts. It is mounted on a spring mechanism or adjustable pivot point. The tensioner guarantees that the belt provides adequate tension while driving, ensuring that the belt can move pulleys that drive components within the engine. If the tensioner or pulley is misaligned, it can throw the serpentine belt’s alignment off, causing the belt to slip or come off entirely.
- How Do You Fix A Tensioner Pulley Noise?: If you’re hearing a squeaky noise coming from your car’s engine, it could be a sign that the serpentine belt tensioner or pulley is misaligned. To fix this, you’ll need to push down on the belt midway between the two uppermost pulleys. If the belt deflects more than one inch, the tensioner is not holding proper tension and will need to be replaced.
- How Do You Replace A Tensioner Pulley?: To replace a tensioner pulley, locate the belt routing diagram, disconnect the battery, remove the old pulley with a 3/8th drive ratchet handle and socket, position the new pulley, and reattach the battery.
Final Word
If you notice that your tensioner arm is binding, sticking, or grinding, it’s time to replace the tensioner. A new tensioner will ensure that your belt is tensioned correctly, and will make sure that your engine runs smoothly.
