You certainly suspect it, but the alternator is a fundamental element in an engine. He is responsible for changing energy of the engine of this Volvo 264 in Electricity supply so as to recharge the battery. If there is ever a malfunction, it can therefore usually cause electrical failures. It therefore seems essential to deal with it. However, the malfunction can also come from your belt, sometimes pulleys. We will discover in this article where the problems selon le noise that comes out.noise-alternator Volvo-264

Noise alternator belt on a Volvo 264

La alternator belt, also called an accessory belt, is the essential element that contributes to the proper functioning of the alternator. It is the latter which, through its convolution, drives the alternator and will provide the means to produce electricity. However, it also serves to train others pumps of the motor. If it breaks, it can cause damages really important in the Volvo 264 engine.

A metallic noise on the Volvo 264:

This is a hazard that usually comes Cold. The most common source is that some of the streaks on the belt turn out to be damaged. However, it can also happen if the pulley is slightly offset. If the belt breaks down, it can of course break. If you distinguish this sound, the ideal remains to change the belt and the malfunction will be repaired almost without fail.

A sharp squeal on the Volvo 264:

This is the most common concern, as well as the least serious. It usually comes from cold, but can reappear even when hot sometimes. However, it suddenly disappears. This inconvenience usually comes when the accessory belt is not tight enough. All you need is tender and voila. Be careful, when it stays in this state for a long time, the belt can be damaged and cause a more dramatic problem in the long term. This acute screeching also sometimes occurs when the damper pulley is damaged, but it is rather rare.

A slight hiss or breath on the Volvo 264:

It is the opposite of the concern of the last example. The strap is probably far too tight or too short. You know what you need to do!

Alternator noise on a Volvo 264

In the event that it is really the alternator which produces this sound and not your belt, then the concerns are fundamentally different. However, this sound you hear can have similarities to that of a strap, i.e. high hiss. The malfunction may result from a electrical failure, this remains quite frequent. If it happens that the voltage necessary for the good activity of the Volvo 264 is usually deficient, it can usually be seen in the lack of intensity of the indicator lights or lights inside your automobile. Assuming insufficient intensity is out of the ordinary, it may be that the battery indicator stays in operation. So as to carry out a real diagnostic malfunction, it is useful to use a voltmeter and check the tension on the + and the least of its battery, the engine running of course. If the voltage is lower than that suggested on the battery, the malfunction will come from the alternator. In this case, it usually needs to be changed.

Conclusion:

A new alternator sound usually comes from the alternator belt, but may also come from the alternator itself. Economically, the alternator belt is much cheaper than the alternator. Ask for an estimate at a mechanic before embarking on repairs, since you are not necessarily certain of the source of the malfunction.
