You can imagine it, but the alternator is a determining component in an engine. This is the one who is responsible for changing energy of the engine of this Renault Scenic in Electricity supply so as to recharge the battery. In the specific case where there is a problem, this could therefore essentially cause electrical failures. It is therefore essential to take care of it. However, the malfunction could also be due to the belt, and even pulleys. We will see in this article where the problems according to the noise which is issued.
Noise of the alternator belt on a Renault Scenic
La alternator belt, also called the accessory belt, is the essential component which contributes to the good action of the alternator. It is this one which by its convolution carries the alternator and will provide the means to manufacture electricity. But it also serves to train different pumps of the motor. If it breaks, it can cause damages rather important in the engine of the Renault Scenic.
A metallic noise on the Renault Scenic:
Here is a hazard that generally comes Cold. The most common cause is that the ridges in the belt are damaged. But it could also happen if the pulley is out of gon a little bit. If the belt gets damaged it can obviously break. If you recognize this sound, it is best to replace the belt and the malfunction will be fixed almost certainly.
A high-pitched screeching sound on the Renault Scenic:
This is the most common concern, as well as the least important. It is usually made cold, but could come even hot sometimes. Nonetheless, it stops instantly. This inconvenience usually comes from the case where the accessory belt is not tight enough. All you need to do is tender and voila. Be careful, when it remains in this situation for too long, the belt can be damaged and eventually cause a more dramatic incident. This high-pitched screeching also occurs at times when the damper pulley is damaged, but it is rather rare.
A slight whistling or hissing sound on the Renault Scenic:
This is the reverse of the previous concern. Your belt is probably too tight or too small. You know what you have left to do !
Alternator noise on a Renault Scenic
When it is really the alternator that makes this sound and not the belt, then the issues will be completely divergent. However, this sound emitted may have similarities compared to that of a belt, so a high hiss. The concern could arise from a electrical failure, this remains rather frequent. In case the voltage essential to the good activity of the Renault Scenic is usually weak, this is generally seen when there is a lack of liveliness of the lights or bulbs within the vehicle. In case the lack of liveliness is evident, it is possible that the battery indicator stay on. If you want to do a real diagnostic of this concern, it is possible to use a voltmeter to thus check the tension via the + and - of the battery, with the ignition on of course. Assuming that the voltage is lower than that recommended on the battery, the malfunction could therefore come from the alternator. In this case, it usually needs to be replaced.
Conclusion:
An alternator sound usually comes from the alternator belt, but could also come from the alternator itself. Economically, an alternator belt costs considerably less compared to the alternator. Ask for an estimate at a mechanic before attempting any work, since one is not necessarily sure of the source of the malfunction. We hope this guide has helped you, in this case we invite you to write a comment. See you soon with your Renault Scenic.
