You certainly suspect it, however the alternator is a fundamental element in an engine. He is the one who guarantees to change energy the engine of your Volvo 123 in Electricity supply in order to recharge the battery. If there is ever a problem, it can especially cause electrical failures. It therefore seems essential to resolve the problem. Only, the concern can also come from the belt, sometimes pulleys. We will find out through this guide where the problems according to the noise which is issued.noise-alternator Volvo-123

Noise alternator belt on a Volvo 123

La alternator belt, also called accessory belt, happens to be the essential component which contributes to the proper functioning of the alternator. It is this which via its convolution drives the alternator and makes it possible to create electricity. However, it also serves to train others pumps of the motor. If it breaks, it could cause damages very important in your Volvo 123 engine.

A metallic noise on the Volvo 123:

This is a hazard that often comes Cold. The most common reason is that some of the streaks in the belt are damaged. However, this can also happen as soon as the pulley is an offset skewer. If the belt deteriorates it could naturally break. If you ever identify this sound, the ideal is to change the belt and the problem will be repaired almost every time.

A sharp squeal on the Volvo 123:

This remains the most recurring concern, as well as the least dramatic. It usually comes from cold, but may reappear when you drive from time to time. However, it stops instantly. This problem often arises as soon as the accessory belt is not tight enough. It is necessary to tender and it's won. Be careful, if it remains in this situation for too long, the belt could deteriorate and cause a more serious malfunction at the end. This sharp screeching also sometimes occurs when the damper pulley is damaged, however it is less frequent.

A slight hiss or breath on the Volvo 123:

It is the reverse of the previous concern. Your belt may be too tight or too short. You can imagine what you are going to have to do!

Alternator noise on a Volvo 123

If it is the alternator that makes the sound and not your belt, then the worries will be quite different. However, this sound that you hear could have resemblances compared to that of a belt, i.e. a high hiss. The concern may arise from a electrical failure, it is quite usual. If it happens that the voltage essential for the good activity of the Volvo 123 is low, it is often seen in the lack of intensity of the lights or bulbs in the car. Assuming that the insufficient intensity is excessive, it happens that the battery indicator can be in operation. So as to achieve real diagnostic worry, it is quite feasible to use a voltmeter to probe the tension on the plus and minus of your battery, with the engine running obviously. Assuming that the voltage is lower than that recommended on the battery, the problem may therefore arise from the alternator. In this situation, it will usually have to be changed.

Conclusion:

A new alternator sound often comes from the alternator belt, but may also come from the alternator itself. Economically, an alternator belt is relatively cheaper compared to the alternator. Have a costing done at a auto repairer before attempting work, since we are in no way sure of the source of the problem. Hope this post helped you, if so you can leave a comment. Enjoy the road with your Volvo 123.
