It may not be unknown to you, however the alternator is a vital element in an engine. He himself is responsible for transforming energy the engine of your Volvo S70 in Electricity supply in order to recharge the battery. If there is ever a malfunction, this could consequently lead to a majority of electrical failures. It is therefore essential to resolve the problem. However, the dysfunction could mainly come from its belt, and even pulleys. We will discover through this post where will be able to come from problems related to noise which is issued.
Noise alternator belt on a Volvo S70
La alternator belt, also known as an accessory belt, is the essential component that contributes to the proper functioning of the alternator. It is it which, through its rotation, drives the alternator and creates electricity. But it also serves to rotate different pumps of the motor. If it ever destroys, it can make damages frankly important in the engine of the Volvo S70.
A metallic noise on the Volvo S70:
Here's a noise that usually comes Cold. The most common source is that the streaks in the belt will be damaged. But it can also occur as soon as the pulley is an offset offset. In the event that the belt is stretched, it can of course break. If you ever recognize this noise, it is best to change the belt and the malfunction will be repaired almost without fail.

Alternator noise on a Volvo S70
When it is really the alternator that makes the noise and not your belt, then the problems are really different. However, the noise you hear may have resemblances compared to that of a belt, so a high hiss. The problem may come from electrical failure, it's pretty ordinary. If it happens that the voltage necessary for the good activity of your Volvo S70 remains low, this is often seen in the lack of intensity of the lights or lights inside your automobile. If the insufficient intensity is evident, it is possible that the battery indicator stays in operation. If you want to make a good diagnostic of your problem, it is quite feasible to use a voltmeter to check the tension on the plus and the - of the battery, the engine running of course. Assuming that the voltage is found to be lower than that recommended on the battery, the malfunction will therefore come from the alternator. So you usually need to change it.
Conclusion:
A new alternator noise generally comes from the alternator belt, but may also come from the alternator itself. financially, an alternator belt is much cheaper compared to the alternator.
