It may not be unknown to you, nevertheless the alternator is a determining element in an engine. It is he himself who is responsible for transforming energy of the engine block of this Volvo 164 in Electricity supply so as to recharge the battery. In the specific case where there is a problem, it could therefore mainly cause electrical failures. It is therefore essential to take care of it. Only, the concern could also come from the belt, or even pulleys. We will discover thanks to this post where can come from problems according to the noise which is issued.
Noise alternator belt on a Volvo 164
La alternator belt, also called accessory belt, is the essential element which contributes to the good action of the alternator. It is this one which, thanks to its convolution, drives the alternator and makes it possible to create electricity. But this one also serves to train others pumps of the engine block. In the event that it breaks, it can cause damages rather important in your Volvo 164 engine.
A metallic noise on the Volvo 164:
Here is a hazard that usually comes Cold. The most common reason is that part of the ridges on the belt will be damaged. But it could also occur if the pulley is out of gon a little bit. If the belt gets damaged it can obviously break. If it happens that you recognize this sound, the ideal will be to change the belt and the problem will be almost certainly solved.
A sharp squeal on the Volvo 164:
It is the most common problem, as well as the least critical. It is often cold grown, but can recur when you drive once in a while. Yet it stops promptly. This inconvenience usually arises when the accessory belt is not tensioned enough. All you need to do is tighten and it's over. Small warning, in the event that it remains in this state too long, the belt can be damaged and cause a more serious problem at the end. This high-pitched noise also sometimes occurs when the damper pulley happens to be deteriorated, nevertheless it is less frequent.
A slight hiss or breath on the Volvo 164:
This is the opposite of the previous problem. The belt is probably too tight or too short. You know what to do!
Alternator noise on a Volvo 164
When it is indeed the alternator which makes the sound and not your belt, then the concerns are really different. However, the sound you hear may have some similarities to that of a belt, i.e. a high hiss. The problem may arise from electrical failure, this is still quite common. If the voltage necessary for the good activity of this Volvo 164 remains deficient, this is usually seen when there is a lack of intensity of the warning lights or lights within your automobile. If ever the insufficient intensity is out of the ordinary, it happens that the battery indicator stays on. So as to make a good diagnostic of this problem, it is possible to use a voltmeter to check the tension on the + and - of its battery, the engine obviously running. Assuming that the voltage is lower than that suggested by the battery, the problem could therefore come from the alternator. In this case, it will usually need to be changed.
Conclusion:
A new alternator sound usually comes from the alternator belt, but can also come from the alternator itself. Economically, an alternator belt is much cheaper compared to the alternator. Get the price from a mechanic before attempting any work, since we can never be sure of the origin of the problem. Hope this text has helped you, if so you can post a comment. Have a good ride with your Volvo 164.
