As you can imagine, the alternator is an essential element in an engine. He himself is the one who guarantees to change energy of the engine block of your Volvo 66 in Electricity supply in order to recharge the battery. In the specific case where there is a concern, it can therefore usually cause electrical failures. It is therefore important to deal with it. However, the concern can mainly come from the belt, sometimes pulleys. We will discover thanks to this text where will be able to come problems according to the noise which is issued.
Noise alternator belt on a Volvo 66
La alternator belt, also called an accessory belt, is the capital element that contributes to the proper functioning of the alternator. It is the latter which, thanks to its convolution, drives the alternator and makes it possible to produce electricity. However, it also serves to spin others pumps of the engine block. If it breaks, the latter will be able to make damages rather important in your engine of this Volvo 66.
A metallic noise on the Volvo 66:
This is a noise that often comes Cold. The most common source is that the streaks on this belt turn out to be damaged. However, it can also happen in the case where the pulley is an offset skewer. If the belt ever runs out, it can obviously break. If you distinguish this sound, the ideal remains to replace the belt and the concern will be solved practically every time.
A sharp squeal on the Volvo 66:
This remains the most ordinary problem, but also the least dramatic. It usually comes cold, but can come back when you drive from time to time. However, it suddenly disappears. This inconvenience generally comes in the case where the accessory belt is not tight enough. It is necessary to tender and it's over. Be careful, when it remains in this situation for too long, the belt may become damaged and cause more serious malfunction over time. This sharp screeching also happens sometimes when the damper pulley happens to be damaged, however it is less common.
A slight hiss or breath on the Volvo 66:
It is the reverse of the previous problem. Your strap is probably far too tight or too short. You can imagine what you should do!
Alternator noise on a Volvo 66
In the event that it is the alternator that produces this sound and not your belt, then the malfunctions will be totally singular. However, this sound that you hear may resemble that of a belt, i.e. a high hiss. The concern may arise from a electrical failure, this is relatively common. If ever voltage essential for the good activity of your Volvo 66 is low, it generally refers to the lack of intensity of the indicator lights or bulbs in your automobile. Assuming the intensity is obvious, it may be that the battery indicator is on. If you want to make a real diagnostic of this concern, it is quite feasible to use a voltmeter in order to take the tension via the plus and the - of the battery, with the engine running naturally. If the voltage is lower than that recommended on the battery, the problem will come from the alternator. In this case, it will usually need to be replaced.
Conclusion:
An alternator sound often comes from the alternator belt, but can also come from the alternator itself. financially, an alternator belt is much cheaper than the alternator. Get a quote from a mechanic rather than starting work, because we are not necessarily sure of the source of the problem. Hoping that this post has served you something, in this case you can leave a comment. Have a good ride with your Volvo 66.
