It may not be unknown to you, however the alternator is an essential component in an engine. It is he himself who is responsible for transforming energy of the engine block of your Volvo 343 in Electricity supply in order to recharge the battery. In the specific case where there is a malfunction, it could cause most of the electrical failures. It is therefore essential to take care of it. However, the problem could also be its belt, sometimes pulleys. We will discover through this post where can come problems selon le noise that you hear.noise-alternator Volvo-343

Noise alternator belt on a Volvo 343

La alternator belt, also referred to as the accessory belt, is the most important component that contributes to the proper functioning of the alternator. It is he who by his rotation carries the alternator and will provide the means to create electricity. However, it also serves to turn other pumps of the engine block. If it destroys, the latter can make damages very serious within the engine of this Volvo 343.

A metallic noise on the Volvo 343:

It’s usually a noise Cold. The most common reason is that some of the ridges on this belt are damaged. However, it could also occur when the pulley is very slightly off-center. If the belt ever breaks it can of course break. If you happen to notice this sound, the best thing to do is replace the belt and the problem will be fixed almost every time.

A sharp squeal on the Volvo 343:

It is the most common hassle, but also the least dramatic. It is usually made cold, but can come even hot sometimes. However, he stops abruptly. This noise usually comes when the accessory belt is not tight enough. It will suffice to tighten and it is done. Small warning, if it remains in this state for too long, the belt may deteriorate and eventually cause a more serious malfunction. This sharp screeching also occurs at times when the damper pulley happens to be damaged, however it is rather rare.

A slight hiss or breath on the Volvo 343:

It is the opposite of the hassle before. Your belt is probably too tight or too short. You can imagine what you have to do!

Alternator noise on a Volvo 343

In the event that it is indeed the alternator which makes the sound and not your belt, in this situation the problems will be fundamentally unique. However, this sound that we hear may have similarities to that of a belt, that is to say a high hiss. The concern can arise from a electrical failure, this remains relatively ordinary. If it happens that the voltage useful for the good activity of the Volvo 343 remains weak, it is generally seen when there is a lack of liveliness of the lights or bulbs inside the car. If ever the lack of liveliness is out of the ordinary, it happens that the battery indicator can be in operation. So as to make a good diagnostic worry, it is useful to use a voltmeter and take the tension via the + and - of the battery, the engine is running of course. If the voltage happens to be lower than that recommended by the battery, the problem could therefore come from the alternator. So it usually needs to be replaced.

Conclusion:

An alternator sound generally comes from the alternator belt, but can also come from the alternator itself. financially, the alternator belt costs considerably less than the alternator. Ask for an estimate at a mechanic before embarking on repairs, quite simply because we are not necessarily sure of the source of the problem. We hope that this post has served you for something, in this case we invite you to leave a comment. Have a good trip with your Volvo 343.
