It may not be unknown to you, but the alternator is a fundamental part of an engine. It is this one who is responsible for changing energy the engine of your Nissan Micra 4 in Electricity supply in order to recharge the battery. If there is a malfunction, it could therefore mainly cause electrical failures. It is therefore important to take care of it. However, the problem could also stem from its belt, and even pulleys. Thanks to this guide, we are going to discover where the problems related to noise that comes out.noise-alternator-Nissan-Micra-4

Noise alternator belt on a Nissan Micra 4

La alternator belt, also called the accessory belt, turns out to be the essential element which contributes to the good functioning of the alternator. It is this one which through its convolution carries the alternator and will create electricity. But it is also used to make different pumps of the motor. In the event that it breaks, the latter may cause damages rather serious in the engine of the Nissan Micra 4.

A metallic noise on the Nissan Micra 4:

Here is a hazard that generally comes Cold. The most common source is that some of the ridges on the belt turn out to be damaged. But this can also happen when the pulley is very slightly off-center. If the belt breaks, it may naturally break. If you happen to recognize this sound, it will be ideal to replace the belt and the problem will almost certainly be fixed.

A sharp squeal on the Nissan Micra 4:

It is the most recurring problem, as well as the least serious. It often comes cold, but can come back when you are driving from time to time. However, he stops abruptly. This noise usually comes when the accessory belt is slack. All you need to do is tighten and voila. Be careful, when it remains in this situation for too long, the belt may be damaged and cause a more serious incident at the end. This high-pitched screeching also sometimes occurs when the damper pulley happens to be damaged, however it is rarer.

A slight hiss or breath on the Nissan Micra 4:

This is the reverse of the problem in the last example. The belt is probably too tight or too short. You can imagine what you have to do!

Alternator noise on a Nissan Micra 4

In the event that it is really the alternator which creates this sound and not the belt, in this situation the problems will be found to be totally singular. However, the sound you hear may have some similarities to that of a belt, which means a high hiss. The malfunction can come from a electrical failure, it's quite common. If the voltage necessary for the good activity of this Nissan Micra 4 is low, this is usually seen when the intensity of the warning lights or lights within the car is too low. If the lack of intensity is evident, it happens that the battery indicator is on. So as to make a good diagnostic of your malfunction, it is possible to use a voltmeter to probe the tension via the plus and the - of your battery, with the ignition on obviously. Assuming that the voltage turns out to be lower than that recommended by the battery, the problem could therefore come from the alternator. In this situation, it usually needs to be replaced.

Conclusion:

A new alternator sound generally comes from the alternator belt, but can also come from the alternator itself. Economically, the alternator belt is much cheaper compared to the alternator. Ask the price at a auto repairer rather than starting repairs, as you are by no means certain of the cause of the problem. Hope this post has helped you, if so you can leave a comment. Have a good trip with your Nissan Micra 4.
