You may already know this, but the alternator is a determining factor in an engine. He is the one who is responsible for transforming energy of the engine of this Volvo 122 in Electricity supply so as to recharge the battery. In the specific case where there is a malfunction, it can thus cause most of the electrical failures. It is therefore essential to pay attention to it. However, the concern can also come from its belt, or even pulleys. We will discover through this post where will be able to come from problems according to the noise that comes out.
Noise alternator belt on a Volvo 122
La alternator belt, also called accessory belt, is the essential element that contributes to the proper functioning of the alternator. It is this which via its rotation takes the alternator and will create electricity. However, it also serves to rotate other pumps of the motor. In the event that it breaks, the latter may make damages pretty serious within the engine of this Volvo 122.
A metallic noise on the Volvo 122:
Here is a hazard that generally comes Cold. The most common cause is that part of the streaks on this belt will be damaged. However, this could also occur if the pulley is a tantiner out of the gon. If the belt deteriorates, it can naturally break. If you recognize this noise, it is best to change the belt and the problem will be corrected almost every time.
A sharp squeal on the Volvo 122:
This remains the most recurring, and least critical, hassle. It usually comes from cold, but can reappear when you sometimes drive. However, it stops suddenly. This inconvenience generally comes in the case where the accessory belt is not tight enough. Just the tighten and it's won. Warning, when it remains in this state for too long, the belt may deteriorate and cause more serious concern over time. This sharp squeak also occurs sometimes when the damper pulley is damaged, but it is rarer.
A slight hiss or breath on the Volvo 122:
It's the opposite of the hassle of the last example. Your belt is probably far too tight or even too small. You know what you are going to have to do!
Alternator noise on a Volvo 122
When it is indeed the alternator which produces this noise and not your belt, in this case the malfunctions will be entirely different. However, this emitted noise may have similarities compared to that of a belt, i.e. a high hiss. The problem may arise from a electrical failure, this remains fairly usual. If it happens that the voltage essential for the good activity of your Volvo 122 remains insufficient, it is generally seen in the lack of intensity of the indicator lights or lights inside the vehicle. Assuming the lack of intensity is evident, it may be that the battery indicator stays in operation. So as to make a real diagnostic of your problem, it is still possible to use a voltmeter to check the tension on the plus and the - of its battery, with the ignition on obviously. Assuming that the voltage is lower than that suggested by the battery, the problem could therefore arise from the alternator. In this case, it will usually need to be changed.
Conclusion:
A new alternator noise generally comes from the alternator belt, but can also come from the alternator itself. Economically, the alternator belt is much cheaper compared to the alternator. Get the price from a mechanic rather than attempting work, since you can never be sure of the source of the problem. We hope that this text was useful to you, in which case you can leave a comment. See you soon with your Volvo 122.
