It may not be unknown to you, however the alternator is a vital component within an engine. He himself is responsible for transforming energy the engine of your Toyota Auris in Electricity supply in order to recharge the battery. If there is a malfunction, it could therefore essentially cause electrical failures. It is therefore capital to pay attention. Only, the concern could also come from his belt, or even pulleys. We will see in this post where will be able to come problems according to the noise that comes out.noise-alternator-Toyota-Auris

Noise alternator belt on a Toyota Auris

La alternator belt, also called an accessory belt, is the essential element that contributes to the proper functioning of the alternator. It is this one which thanks to its convolution drives the alternator and will allow electricity to be created. But it also serves to operate other pumps of the motor. In the event that it breaks, it may make damages very serious in your engine of this Toyota Auris.

A metallic noise on the Toyota Auris:

It’s a noise that usually comes Cold. The most common cause is that the streaks on this belt are damaged. But this can also happen if the pulley is a little off-center. If the belt gets loose, it can of course break. If it happens that you identify this sound, the best will be to replace the belt and the problem will be erased almost every time.

A sharp squeal on the Toyota Auris:

Indeed, this is the most ordinary hassle, but also the least dramatic. It usually comes cold, but can come back when you are driving at times. However, it disappears instantly. This noise often comes when the accessory belt is slack. It will suffice tighten and it's done! Small warning, when it remains in this situation too long, the belt may be damaged and cause more serious concern in the long term. This sharp squeak also sometimes occurs in the event that the damper pulley happens to be damaged, however it is rather rare.

A slight hiss or breath on the Toyota Auris:

It's the opposite of the hassle of the last example. Your belt is certainly excessively tight or even too short. You can imagine what you should do!

Alternator noise on a Toyota Auris

If it is really the alternator that creates this sound and not the belt, in this situation the problems are fundamentally different. However, this sound we hear may have similarities to that of a strap, so a high hiss. The malfunction can come from a electrical failure, it is relatively frequent. If it happens that the voltage essential to the proper functioning of the Toyota Auris is insufficient, it is often seen during a lack of alertness of lights or lights within the vehicle. If the alertness is unusual, it is possible that the battery indicator stays on. So as to make a real diagnostic of your malfunction, it is useful to use a voltmeter in order to probe the tension via the + and the least of your battery, with the engine running of course. Assuming that the voltage is lower than that suggested by the battery, the problem will actually come from the alternator. So you usually need to replace it.

Conclusion:

An alternator sound generally comes from the alternator belt, but can also come from the alternator itself. Economically, an alternator belt is much cheaper compared to the alternator.
