It may not be unknown to you, however the alternator is a fundamental component in an engine. It is this one which is responsible for transforming energy of the engine block of this Nissan Micra 3 in Electricity supply in order to recharge the battery. In the specific case where there is a malfunction, it can therefore usually cause electrical failures. It remains essential to pay attention to it. However, the problem may mainly arise from its belt, and even pulleys. We are going to discover in this guide where the problems related to noise that you hear.noise-alternator-Nissan-Micra-3

Noise alternator belt on a Nissan Micra 3

La alternator belt, also called accessory belt, is the essential element which contributes to the good action of the alternator. It is it which through its convolution drives the alternator and will make it possible to produce electricity. However, it also serves to rotate other pumps of the engine block. If it breaks, it can cause damages very important in your engine of this Nissan Micra 3.

A metallic noise on the Nissan Micra 3:

This is a noise that often comes Cold. The most common cause is that some of the streaks on this belt turn out to be damaged. However, it can also occur when the pulley is slightly offset. If the belt is ever torn, it can obviously break. If it happens that you recognize this sound, the best thing to do is to change the belt and the problem will be solved almost every time.

A sharp squeal on the Nissan Micra 3:

This remains the most common hassle, but also the least important. It usually comes from cold, but will sometimes reappear even from time to time. Nevertheless, it stops quickly. This inconvenience usually comes when the accessory belt is not tight enough. It will suffice tighten and it's over. Small warning, if it remains in this state for too long, the belt can be damaged and cause a more serious problem in the long term. This sharp noise also occurs at times when the damper pulley happens to be damaged, however it is rather rare.

A slight hiss or breath on the Nissan Micra 3:

It's the reverse of the hassle before. The belt is probably excessively tight or too short. You know what you have left to do !

Alternator noise on a Nissan Micra 3

If it is indeed the alternator that makes the sound and not your belt, then the malfunctions will be found to be quite divergent. However, the sound emitted may have similarities compared to that of a strap, which means a high hiss. Sometimes the problem will come from electrical failure, it's pretty ordinary. If ever voltage essential to the proper functioning of this Nissan Micra 3 is usually insufficient, it is usually seen in the lack of intensity of the indicator lights or bulbs in the car. If the intensity gap is excessive, it happens that the battery indicator is on. So as to proceed with a good diagnostic of this problem, it is still useful to use a voltmeter in order to probe the tension via the plus and minus of its battery, with the engine running of course. If the voltage is lower than that recommended by the battery, the problem will consequently come from the alternator. In this case, it will generally have to be changed.

Conclusion:

A new alternator sound often comes from the alternator belt, but sometimes will also come from the alternator itself. Economically, an alternator belt is much cheaper than the alternator. Ask the price at a mechanic rather than attempting work, simply because we are in no way assured of the source of the problem. We hope this post served you something, if that's the case don't hesitate to post a comment. Enjoy the road with your Nissan Micra 3.
