As you can imagine, the alternator is a determining component within an engine. He is the one who is responsible for transforming energy of the engine of this volvo 850 in Electricity supply in order to recharge the battery. If there is ever a problem, it could actually cause mainly electrical failures. It seems in fact essential to resolve the problem. However, the problem could also come from its belt, sometimes pulleys. We will see in this article where the problems according to the noise which is issued.
Alternator belt noise on a Volvo 850
La alternator belt, also called an accessory belt, proves to be the essential element which contributes to the good action of the alternator. It is this which, thanks to its convolution, drives the alternator and will make it possible to produce electricity. But it also serves to operate different pumps of the motor. In the event that it destroys, it may make damages very important in your Volvo 850 engine.
A metallic noise on the Volvo 850:
It is a hazard that often comes Cold. The most common source is that some of the streaks in the belt turn out to be damaged. But it can also happen when the pulley is slightly out of gon. If the belt breaks up, it can obviously break. If you ever identify this noise, the ideal is to change the belt and the problem will be solved almost every time.
A sharp squeal on the Volvo 850:
Indeed, it is the most common dysfunction, as well as the least serious. It is usually issued cold, but may reappear when you drive from time to time. However, it stops quickly. This annoyance usually comes as soon as the accessory belt is relaxed. It will suffice tighten and it's done! Be careful, if it remains in this state for too long, the belt may be damaged and cause a more serious problem in the long term. This sharp squeak also sometimes occurs when the damper pulley is damaged, however it is rarer.
A slight hiss or breath on the Volvo 850:
It is the opposite of the previous dysfunction. The belt is likely to be far too tight or too small. You can imagine what you have to do!
Alternator noise on a Volvo 850
When it is the alternator that creates this noise and not the belt, the hassle will be truly unique. However, the noise you hear may have similarities compared to that of a belt, a high hiss. The problem may come from electrical failure, this remains rather ordinary. If it happens that the voltage essential to the proper functioning of the volvo 850 remains deficient, it is usually seen during a lack of intensity of the indicator lights or lights inside the vehicle. Assuming that the lack of intensity is out of the ordinary, it may be that the battery indicator can be in operation. If you want to make a good diagnostic of the problem, it is quite feasible to use a voltmeter and take the tension via the + and - of your battery, with the ignition on of course. Assuming that the voltage turns out to be lower than that recommended on the battery, the problem could therefore come from the alternator. In this case, you usually need to change it.
Conclusion:
An alternator noise often comes from the alternator belt, but can also come from the alternator itself. financially, the alternator belt is relatively cheaper compared to the alternator. Ask the price at a mechanic before starting work, simply because we are not necessarily certain of the source of the problem. We hope this post helped you, in which case you can post a comment. See you soon with your volvo 850.
