You may already know this, but the alternator is an essential part of an engine. It is he who is responsible for changing energy of the engine of this Volkswagen Golf 7 Sw R in Electricity supply in order to recharge the battery. If there is a problem, this can lead mainly to electrical failures. It is therefore important to take care of it. However, the problem can also come from the belt, or even pulleys. We will see through this post where will be able to come problems related to noise that comes out.noise-alternator-Volkswagen-Golf-7-Sw-R

Noise of the alternator belt on a Volkswagen Golf 7 Sw R

La alternator belt, also referred to as the accessory belt, is the essential element which contributes to the proper functioning of the alternator. It is this one which, through its convolution, drives the alternator and will allow electricity to be produced. However, this is also used to operate different pumps of the motor. In case it breaks, it can make damages rather important in the engine of the Volkswagen Golf 7 Sw R.

A metallic noise on the Volkswagen Golf 7 Sw R:

Here is a hazard that usually comes Cold. The most common reason is that part of the ridges in the belt have deteriorated. However, it could also occur as soon as the pulley is very slightly off-center. If the belt does fall apart it can naturally break. If you can see this sound, the best thing you can do is replace the belt and the problem will be fixed almost every time.

A high-pitched screeching noise on the Volkswagen Golf 7 Sw R:

This is the most common malfunction, as well as the least important. It usually comes cold, but could reappear when you are driving sometimes. However, it stops instantly. This problem usually arises when the accessory belt is slack. It is necessary to tender and it is done. Small warning, when left in this situation for a long time, the belt can get damaged and cause a more dramatic malfunction in the end. This sharp noise also occurs sometimes in the event that the damper pulley happens to be deteriorated, however it is more rare.

A slight whistling or hissing sound on the Volkswagen Golf 7 Sw R:

This is the reverse of the malfunction before. The belt is certainly too tight or too short. Can you imagine what you are going to have to do!

Alternator noise on a Volkswagen Golf 7 Sw R

Suppose that it is indeed the alternator which makes the sound and not the belt, in this case the malfunctions will be quite unusual. However, this sound emitted may have resemblances to that of a belt, i.e. a high hiss. The concern could arise from a electrical failure, this remains quite frequent. If ever voltage essential for the proper functioning of the Volkswagen Golf 7 Sw R is deficient, this is usually seen when there is a lack of liveliness of the warning lights or lights within the vehicle. If ever the lack of liveliness is out of the ordinary, it happens that the battery indicator can be running. So as to make a good diagnostic worry, it is still quite feasible to use a voltmeter and take the tension via the + and - of your battery, with the engine running of course. If ever the voltage is found to be lower than that recommended by the battery, the problem will in fact come from the alternator. In this specific case, it will usually need to be replaced.

Conclusion:

An alternator sound usually comes from the alternator belt, but could also come from the alternator itself. Economically, the alternator belt costs considerably less compared to the alternator. Get the price from a mechanic rather than launching yourself into work, quite simply because you are never sure of the source of the problem. We hope this post has helped you, if so we invite you to post a comment. Enjoy the road with your Volkswagen Golf 7 Sw R.
