Ways To Detect Early Signs of Serpentine Belt Tensioner Failure in European Cars

The serpentine belt tensioner in your luxury European car plays a leading role in the efficient functioning of certain major components under the hood of your vehicle. In fact, the belt tensioner is responsible for maintaining proper tension on the serpentine belt that helps in the operation of several engine accessories.

However, issues with the functioning of the serpentine belt tensioner in your European car can lead to various problems that will make it difficult for you to drive your car smoothly. In this article, we will discuss the early signs to help detect serpentine belt failure in European cars.

Unusual Squealing or Chirping Sound

One of the leading signs that something is wrong with the functioning of the serpentine belt in your European car is when you hear an unusual squealing or chirping sound coming from under the hood of your car. You are going to come across a very high-pitched squealing or chirping sound that becomes audible during the starting, acceleration, and running of the AC compressor.

This is mostly caused by the tensioner’s inability to apply adequate pressure, which allows the serpentine belt to slip temporarily over one or more of the pulleys. In fact, the sound you hear is caused by the friction of the rubber belt slipping against the metal or plastic pulley surface.

There is no doubt that a failing serpentine belt can also lead to these unusual noises; however, a malfunctioning belt tensioner is the leading cause behind the problem. You must get your high-end car inspected by a certified auto repair shop immediately to help deal with the problem.

Increased Serpentine Belt Wear

The failure of the serpentine belt tensioner is going to take a toll on the integrity of the serpentine belt itself, and conducting a visual inspection of the belt is going to reveal it. That is why you must have a look at the edges of the serpentine belt for signs of fraying, shredding, or glazing that will help determine the extent of the damage.

In addition to that, you must also look for cracks on the ribbed side of the belt or for missing chunks of rubber that indicates a damaged serpentine belt tensioner in your high-end car. Most of the time, it is observed that a misaligned or wobbly tensioner pulley leads to the belt developing cracks on its edges.

Furthermore, the inadequate tension allows the belt to slip, and this leads to a lot of heat that often causes glazing and cracking. Often, it is seen that a seized tensioner does lead to the buildup of too much tension, and stretches the belt, leading to its premature failure.

Erratic or Failing Accessories

The serpentine belt plays a critical role in the optimal functioning of the important components under the hood of your vehicle. Most of the time, it is seen that when the serpentine belt tensioner fails, the accessories dependent on the serpentine belt face issues with their functioning.

During this time, you might face issues with the functioning of the air conditioning system as it will blow out warm air. In addition to that, the power steering system will feel very heavy or inconsistent, and the functioning of the headlights in your car will go for a toss as it might dim or brighten erratically.

In fact, the consistent spinning of the respective pulleys connected to the serpentine belt makes these accessories function efficiently. However, as the belt tensioner is damaged, the serpentine belt won’t be consistent enough, which leads to erratic functioning of these accessories in your European car.

Misaligned Tensioner Pulley

The path of the serpentine belt is something that you must definitely have a look at in order to determine serpentine belt tensioner failure in your European car. While inspecting the serpentine belt, all the pulleys must be in the exact same plane.

However, if the tensioner pulley appears to be tilted forward or backward, then its internal bearing or bushing are damaged and needs to be inspected immediately. Often this misalignment is the major cause behind the shredding of the serpentine belt.
