It may not be unknown to you, however the alternator is a fundamental element in an engine. He is the one who is responsible for transforming energy of the engine of this Toyota Auris 2 in Electricity supply in order to recharge the battery. In the specific case where there is a problem, this can cause most of the electrical failures. It is therefore crucial to pay attention to it. However, the malfunction can also come from your belt, sometimes pulleys. We will discover through this post where the problems related to noise that comes out.noise-alternator-Toyota-Auris-2

Noise of the alternator belt on a Toyota Auris 2

La alternator belt, also called accessory belt, happens to be the capital component which contributes to the good action of the alternator. It is this which via its convolution drives the alternator and will provide the means to produce electricity. But it also serves to operate other pumps of the motor. If it breaks, it can cause damages rather important within the engine of the Toyota Auris 2.

A metallic noise on the Toyota Auris 2:

This is a hazard that generally comes Cold. The most common reason is that the streaks in the belt are damaged. But it can also happen when the pulley is slightly offset. If the belt breaks up, it can of course break. If you recognize this sound, the ideal thing is to replace the belt and the malfunction will be solved almost every time.

A sharp squeal on the Toyota Auris 2:

Indeed, it is the most frequent hassle, but also the least critical. It usually comes from cold, but can even come back hot sometimes. However, it disappears instantly. This inconvenience often arises as soon as the accessory belt is not tight enough. It is necessary to tighten and it's done.

Alternator noise on a Toyota Auris 2

When it is really the alternator that creates this sound and not your belt, then the problems will be completely different. However, this sound we hear may have similarities compared to that of a belt, a high hiss. The malfunction may come from a electrical failure, this remains rather frequent. In case the voltage essential to the good activity of the Toyota Auris 2 is insufficient, this is often seen in the lack of liveliness of the indicator lights or bulbs inside your automobile. If ever the vivacity is unusual, it happens that the battery indicator either in operation. So as to proceed with a good diagnostic of your malfunction, it is entirely feasible to use a voltmeter to probe the tension via the + and the least of its battery, the ignition on of course. Assuming that the voltage is lower than that recommended on the battery, the malfunction may actually come from the alternator. In this case, it will usually be necessary to replace it.

Conclusion:

A new alternator sound generally comes from the alternator belt, but may also come from the alternator itself. financially, the alternator belt is relatively cheaper than the alternator.
