You may already know this, but the alternator is a vital component in an engine. It is he himself who is responsible for transforming energy of the engine block of this Volvo 460 in Electricity supply in order to recharge the battery. If there is a malfunction, it could therefore usually cause electrical failures. It is therefore important to take care of it. Only, the concern could mainly come from your belt, or even pulleys. We will see through this text where the problems selon le noise that comes out.
Noise alternator belt on a Volvo 460
La alternator belt, also known as the accessory belt, is the essential component involved in the proper functioning of the alternator. It is he who by his convolution carries the alternator and will allow the creation of electricity. However, this is also used to operate different pumps of the engine block. If it ever breaks, it can make damages very important within the engine of the Volvo 460.
A metallic noise on the Volvo 460:
Here is a noise that often comes Cold. The most common cause is that the ridges in the belt will be damaged. However, it could also happen when the pulley is a stick out of gon. If the belt gets damaged it can naturally break. If you can see this sound, the best thing to do is to change the belt and the problem will almost certainly be solved.
A sharp squeal on the Volvo 460:
Indeed, it is the most common problem, but also the least serious. It is often made cold, but will sometimes reappear even hot from time to time. Nevertheless, he suddenly disappears. This problem usually arises when the accessory belt is slack. All you need to do is tighten and it's won. Small warning, when it remains in this situation too long, the belt can deteriorate and cause a more serious problem at the end. This sharp noise also appears sometimes when the damper pulley happens to be damaged, however it is rarer.
A slight hiss or breath on the Volvo 460:
This is the reverse of the previous problem. The belt is certainly excessively tight or even too small. Can you imagine what you are going to have to do!
Alternator noise on a Volvo 460
Assuming it's really the alternator that makes the sound and not the belt, then the hassles are really peculiar. However, the sound emitted may have similarities compared to that of a belt, so a high hiss. Sometimes the problem will come from electrical failure, this remains relatively ordinary. In case the voltage useful for the good activity of this Volvo 460 remains deficient, this is generally seen in the lack of intensity of the warning lights or lights inside your automobile. If ever the intensity gap is evident, it may be that the battery indicator stay on. In order to make a real diagnostic of your problem, it is useful to use a voltmeter to take the tension on the + and - of your battery, the engine obviously on. Assuming that the voltage is less than that recommended by the battery, the problem may in fact come from the alternator. So it usually needs to be changed.
Conclusion:
An alternator sound often comes from the alternator belt, but will sometimes also come from the alternator itself. financially, an alternator belt is relatively cheaper than the alternator. Ask for an estimate at a mechanic rather than attempting work, because you are never sure where the problem comes from. Hope this article has helped you, if so feel free to post a comment. See you soon with your Volvo 460.
