You can imagine it, but the alternator is a determining element in an engine. This is the one who is responsible for transforming energy the engine block of your Volvo P1800 in Electricity supply in order to recharge the battery. In the specific case where there is a problem, it can therefore mainly cause electrical failures. It therefore seems essential to pay attention to it. However, the concern may also come from its belt, or even pulleys. We will discover through this article where can come from problems selon le noise that you hear.
Noise of the alternator belt on a Volvo P1800
La alternator belt, also known as an accessory belt, is the essential component which contributes to the good action of the alternator. It is this which through its convolution carries the alternator and will allow to produce electricity. However, it also serves to rotate other pumps of the engine block. In the event that it destroys, it could make damages really important in the engine of this Volvo P1800.
A metallic noise on the Volvo P1800:
Here is a noise which generally comes Cold. The most common reason is that some of the streaks on this belt turn out to be damaged. However, this can also happen if the pulley is a little off-center. If the belt becomes loose it could obviously break. If you recognize this sound, the best thing to do is to replace the belt and the problem will be erased almost every time.
A sharp squeal on the Volvo P1800:
Indeed, it is the most usual dysfunction, but also the least important. It is usually made cold, but may return even hot at times. However, it suddenly disappears. This inconvenience generally arises as soon as the accessory belt is relaxed. It will suffice tender and it's done! Small warning, when it remains in this situation for a long time, the belt could be damaged and cause a more serious incident at the end. This sharp screeching also happens sometimes when the damper pulley is damaged, but it is more rare.
A slight hiss or breath on the Volvo P1800:
It is the opposite of the dysfunction of the last example. Your belt is probably too tight or too small. You can imagine what you are going to have to do!
Alternator noise on a Volvo P1800
In the event that it is the alternator that creates this sound and not your belt, in this situation the concerns will be completely divergent. Nevertheless, the sound emitted could have similarities compared to that of a strap, so a high hiss. The malfunction may come from a electrical failure, this remains relatively frequent. If it happens that the voltage useful for the good activity of the Volvo P1800 is usually weak, it is usually seen in the lack of power of the indicator lights or bulbs inside the car. In case the lack of power is out of the ordinary, it is possible that the battery indicator is on. In order to perform a real diagnostic of the malfunction, it is entirely feasible to use a voltmeter and to probe the tension on the + and - of your battery, the ignition on naturally. If the voltage is lower than that recommended on the battery, the problem will actually come from the alternator. In this specific case, it will generally have to be replaced.
Conclusion:
An alternator sound generally comes from the alternator belt, but may also come from the alternator itself. financially, the alternator belt is relatively cheaper than the alternator.
