You might expect it, but the alternator is an essential part in an engine. It is he himself who is responsible for transforming energy of the engine of this Volkswagen Golf 7 in Electricity supply so as to recharge the battery. In the specific case where there is a problem, it could essentially cause electrical failures. It does seem important to take care of it. However, the malfunction could also come from the belt, and even pulleys. We will see thanks to this text where will be able to come from problems according to the noise that you hear.
Noise alternator belt on a Volkswagen Golf 7
La alternator belt, also called the accessory belt, is the essential element which participates in the good action of the alternator. It is the latter which through its convolution carries the alternator and makes it possible to produce electricity. However, this is also used to train different pumps of the motor. If it destroys, it can make damages frankly important in the engine of the Volkswagen Golf 7.
A metallic noise on the Volkswagen Golf 7:
It's a noise that often comes Cold. The most common reason is that the ridges in the belt are damaged. However, this could also happen when the pulley is a little out of axis. If the belt gets damaged it can obviously break. If you do notice this noise, the best thing to do is to replace the belt and the problem will be corrected almost every time.
A sharp squeal on the Volkswagen Golf 7:
It is the most recurring hassle, as well as the least important. It usually comes cold, but may reoccur when you drive every now and then. However, he suddenly stops. This inconvenience usually arises as soon as the accessory belt is slack. It will suffice to tender and it is done. Be careful, when it remains in this state for too long, the belt may be damaged and cause a more serious problem in the long term. This high-pitched screeching also sometimes occurs when the damper pulley is deteriorated, but it is rather rare.
A slight hiss or breath on the Volkswagen Golf 7:
It is the opposite of the previous hassle. The belt is probably too tight or too short. You can imagine what you have to do!
Alternator noise on a Volkswagen Golf 7
If it is the alternator that is making the noise and not your belt, in this situation the malfunctions will be found to be fundamentally different. However, the noise that we hear may have similarities to that of a belt, i.e. high hiss. The dysfunction may arise from a electrical failure, this remains rather usual. If ever voltage necessary for the good activity of this Volkswagen Golf 7 is usually deficient, it is usually spotted when there is a lack of liveliness of the lights or bulbs inside the vehicle. If ever the lack of liveliness is evident, it is possible that the battery indicator can be running. If you want to make a good diagnostic of this malfunction, it is still quite feasible to use a voltmeter to probe the tension via the + and the minus of its battery, with the ignition on naturally. Assuming that the voltage is lower than that recommended by the battery, the malfunction will in fact come from the alternator. In this situation, you will usually need to replace it.
Conclusion:
An alternator noise often comes from the alternator belt, but could also come from the alternator itself. financially, an alternator belt is much cheaper compared to the alternator. Have a costing done at a mechanic before attempting any work, quite simply because you are never sure of the cause of the malfunction. We hope this post has helped you, if so feel free to write a comment. Enjoy the road with your Volkswagen Golf 7.
