Tensioners are effective in the smooth running of the Acura TL vehicle. You can find them on the spring system, and usually, it maintains the belt tension. Despite being effective, sometimes it may emit some noise. The noise is common and affects many users.

Although, you may solve the noise issue by following the recommended steps, then remember to review the manufacturer’s instructions when carrying out the process. Fortunately, the article shows common causes of the noise and how to fix it. However, it offers some signs that will help you know when the tension is terrible, including the FAQs.

Getting rid of the Acura TL tensioner noise

The techniques listed below can assist you in resolving belt noise difficulties.

Tools necessary

1. Squeeze the tensioner

Tighten the Acura TL’s tensioner’s wrench until the entire arm can move in all directions. Take note of the flowing motion as well as the spring tension. A movement that sticks or moves jerkily could indicate a problem with the springs or bearings.

Rotate the arm up and down to see any lateral movement, which could indicate a broken bearing or spring. The vibrations are moderated by various shock-absorbing elements included in some tensioners. Excessive arm motions and chattering are caused by a worn dampener and low spring tension. Tensioners have a finite lifespan because they are wearing parts.

2. Make sure the Acura TL’s pulley is in the right place

Several alignment tools are available to aid in the detection of alignment issues. You’ll have peace of mind knowing that there’s a pulley that’s not in the right place and that you can fix it.

3. Using a spray bottle, saturate the belt tensioner

The process was initially applicable in demonstrating slipping belts or the fact that belt noises vanished after spraying. Because it eliminates Acura TL’s tensioner noise and typically belt-positioning difficulties, this test can be used to separate old pulley bearings. Because oiling the old belts would damage the newer EPDM belts, resulting in more excellent noises, you can utilize only water.

4. Remove the tensioner

If you’re having trouble getting rid of the belt noise, remove it and start the engine. If the noise continues, there could be a problem with the motor or the timing belt. You can inspect the pulleys and belts for any potential concerns with the strap removed.

5. Examine the groove in the Acura TL’s belt

The friction is a result of the belt passing across the pulleys causing the belt to wear out. The grooves in the pulleys wear out as the belt wears, causing the belt to slip.

Acura TL tensioner failure symptoms

Acura TL tensioner failure symptoms

1. A crushing or squealing sound from the belt or tensioner

Belts and tensioner noises are frequently the results of a belt tensioner failure. The problem is most likely a loose tensioner, which would cause the belts to squeak when starting. A bearing or pulley may wear out, resulting in a grinding noise from the pulley.

2. The belt is being worn unusually

If you detect unusual belt wear, it could be a sign of something more serious. If there is an issue with the tensioner pulley, the belt may wear out abnormally quickly. Poorly connected pulleys can cause fraying at the belt’s edges, and in some cases, they can break the straps.

3. Other accessories aren’t working correctly

When the belt tensioner breaks, the belt-driven attachments will surely fail. The alternator, cooling system, and air conditioning system are just a few of the engine accessories that are belt-powered. A blocked or insecure belt tensioner can cause the belt to snap, rendering all linked components useless.

It can lead to issues including overheating, a dead battery, or a faulty AC system. A belt that has collapsed due to the tensioner must usually be fixed to restore the vehicle’s performance.

The Acura TL’s tensioner belting may fail for various causes, including wear and tear or problems with the tensioner. A faulty tensioner may cause the belt and pulley to be triggered, causing the belt to be removed. If you detect a problem with your drive belt tensioner, have it checked out by a qualified mechanic to see if it needs to be repaired.

The Acura TL tensioner’s function

It’s a rubberized belt that links and goes through a series of gears and pulleys. The belt will loosen over time as a result of old age and high temperatures. Loose straps require tight tensioners. Belt tensioners are divided into two types.

1. The hydraulic tensioner is a device that uses hydraulic pressure to maintain tension

It applies steady pressure to the belt to keep it tight and positions the tensioner against the strap so that it can move. You can close the open tensioner or pressure the engine oil.

2. The tensioner is operated manually

It is usually done with a spring. Both the engine and the tensioner grind the spring that anchors the engine and tensioner. During the spring season, the belt is kept taut while it stretches.

Symptoms of a faulty tensioner

Symptoms of a faulty tensioner

Tensioners can fail if they become faulty, resulting in a variety of symptoms.

i. When an Acura TL’s tensioner or pulley fails, the belt and pulleys may make high-pitched chirping and rattling noises owing to a lack of tension. Squealing or grinding noises might occur when a pulley bearing entirely collapses.

ii. The belt must be tight for the tensioner to work. The strap can cause harm to numerous components if it is slack. A slap or a knock could be the result.

iii. Though the most common sign of a damaged belt is a specific noise, it can also result in an engine light. It could suggest that one of the valve controls is malfunctioning.

Frequently asked questions:

  • Why is it a risk to drive with a low belt tensioner of the Acura TL?

Operating with a defective belt tensioner is dangerous because the tensioner is supposed to ensure adequate tension that drives devices. The belt tensioner will ultimately age out, causing the belt to move, excessive sound, and a hazardous degree of temperature along with the auxiliary pulley.

  • When will my Acura TL tensioner be replaced?

So there is no way of knowing how often your Acura TL tensioner is to fail. Belt tensioners that have been damaged can break right away, while others can last for a long time.

Nevertheless, if you believe or know the tensioner is defective, you should drive slowly and change this essential factor as soon as possible. Though changing a broken belt tensioner is costly, it is better than any alternative of your Acura TL failing, steering system failing, air conditioning failing, or other equipment failing.


Because it guarantees that the tensioner is proper and capable of moving the Acura TL’s parts, the automobile tensioner is a vital component. One of the most challenging things is to design a belt system. Many factors have an impact on the system, all of which you must consider.

The belt will eventually be silent, efficient, and endure a century if done right. The belt could also be noisy or cause the engine to function inefficiently. If the belt does break, it can cause a lot of trouble.
