You may already know this, however the alternator is a vital component in an engine. He is responsible for changing energy of the engine block of this Toyota Aygo in Electricity supply so as to recharge the battery. If there is ever a problem, it could therefore cause most electrical failures. It therefore seems essential to deal with it. Only, the problem could mainly come from its belt, sometimes pulleys. We will see through this post where will be able to come from problems selon le noise which is issued.noise-alternator-Toyota-Aygo

Noise alternator belt on a Toyota Aygo

La alternator belt, also known as an accessory belt, happens to be the capital element which contributes to the good action of the alternator. It is the latter which, via its convolution, takes the alternator and will make it possible to produce electricity. But it also serves to train different pumps of the engine block. If she ever breaks, she can make damages frankly serious within the engine of the Toyota Aygo.

A metallic noise on the Toyota Aygo:

Here is a noise that usually comes Cold. The most common reason is that some of the streaks in the belt turn out to be damaged. But it can also occur as soon as the pulley is a little out of gon. If the belt becomes loose it can of course break. If you ever recognize this sound, the best thing is to change the belt and the problem will almost certainly be erased.

A sharp squeal on the Toyota Aygo:

This remains the most usual hassle, but also the least dramatic. It is usually made cold, but can come back when you are driving sometimes. However, it stops instantly. This inconvenience generally arises as soon as the accessory belt is relaxed. Just the tender and it's over. Be careful, if it stays in this state for a long time, the belt can be damaged and cause a more serious problem in the long term. This acute screeching also sometimes appears in the event that the damper pulley happens to be damaged, however it is rather rare.

A slight hiss or breath on the Toyota Aygo:

It is the opposite of the previous hassle. The belt is probably far too tight or too short. You can imagine what you should do!

Alternator noise on a Toyota Aygo

When it is really the alternator that makes the sound and not the belt, then the concerns will be fundamentally different. However, this sound you hear may have similarities compared to that of a strap, so a high hiss. The malfunction may result from a electrical failure, this remains fairly usual. In case the voltage useful for the proper functioning of the Toyota Aygo is usually insufficient, it is generally seen during a lack of alertness of the indicator lights or bulbs inside the car. In case the alertness is excessive, it happens that the battery indicator stay on. In order to make a voucher diagnostic of this malfunction, it remains entirely feasible to use a voltmeter and to probe the tension via the + and minus of the battery, with the ignition on of course. Assuming that the voltage is found to be lower than that recommended by the battery, the problem could therefore arise from the alternator. So it will usually have to be changed.

Conclusion:

A new alternator sound usually comes from the alternator belt, but can also come from the alternator itself. Economically, the alternator belt costs much less than the alternator. Have a costing done at a mechanic before starting work, simply because we are in no way assured of the cause of the problem. Hopefully this article has served you something, if so we invite you to leave a comment. Have a good trip with your Toyota Aygo.
