It may not be unknown to you, however the alternator is a critical component in an engine. It is he himself who is responsible for transforming energy of the engine block of this Volkswagen Golf 7 R in Electricity supply so as to recharge the battery. If ever there is a problem, it could therefore usually cause electrical failures. It is therefore important to pay attention to it. However, the problem could also be with your belt, and even pulleys. We are going to discover through this text where the problems related to noise that you hear.noise-alternator-Volkswagen-Golf-7-R

Noise of the alternator belt on a Volkswagen Golf 7 R

La alternator belt, also called the accessory belt, is the essential component which participates in the good action of the alternator. It is the latter which via its convolution carries the alternator and makes it possible to manufacture electricity. However, this is also used to train different pumps of the engine block. In the event that it destroys, this could cause damages frankly important within the engine of the Volkswagen Golf 7 R.

A metallic noise on the Volkswagen Golf 7 R:

This is a noise that generally comes Cold. The most common cause is that part of the ridges in the belt will be damaged. However, this could also occur as soon as the pulley is very slightly out of gon. If the belt gets damaged it could naturally break. If you ever recognize this noise, the best thing to do is change the belt and the problem will be corrected almost every time.

A sharp squeal on the Volkswagen Golf 7 R:

This is the most common concern, but also the least serious. It usually comes cold, but will occasionally come back even hot sometimes. Nevertheless, it quickly disappears. This noise usually comes from when the accessory belt is not tight enough. It will be enough to tighten and it's done !. Be careful, if it remains in this situation for too long, the belt could deteriorate and cause a more serious problem in the long term. This high-pitched screeching also occurs sometimes when the damper pulley is damaged, however it is rather rare.

A slight hiss or breath on the Volkswagen Golf 7 R:

This is the opposite of the previous concern. The belt is probably too tight or too short. Can you imagine what you are going to have to do!

Alternator noise on a Volkswagen Golf 7 R

When it is the alternator that produces this noise and not your belt, in this case the concerns will be fundamentally different. However, this noise that you hear could have similarities compared to that of a belt, that is to say a high hiss. The concern will sometimes arise from a electrical failure, it is quite usual. In case the voltage essential to the proper functioning of the Volkswagen Golf 7 R is weak, it is usually spotted when there is a lack of intensity of the lights or lights inside your automobile. If ever the lack of intensity is excessive, it happens that the battery indicator can be running. In order to proceed with a good diagnostic of this concern, it is quite feasible to use a voltmeter in order to take the tension via the + and the - of the battery, the engine obviously on. Assuming that the voltage is lower than that recommended on the battery, the problem could in fact come from the alternator. So you usually have to change it.

Conclusion:

An alternator noise usually comes from the alternator belt, but will sometimes come from the alternator itself. Economically, the alternator belt is much cheaper compared to the alternator. Request a quote from a mechanic rather than launching into repairs, because you can never be sure of the source of the problem. We hope this guide has been of use to you, if so feel free to leave a comment. Have a good ride with your Volkswagen Golf 7 R.
