You certainly suspect it, however the alternator is an essential component within an engine. It is this one that is responsible for changing energy of the engine of this Renault Vel Satis in Electricity supply so as to recharge the battery. If there is a problem, it could therefore mainly cause electrical failures. It is therefore important to pay attention to it. Only, the concern could also come from the belt, sometimes pulleys. We will discover through this post where will be able to come problems selon le noise that you hear.noise-alternator-Renault-Vel-Satis

Noise of the alternator belt on a Renault Vel Satis

La alternator belt, also known as an accessory belt, is the essential element which contributes to the good action of the alternator. It is this which by its convolution carries the alternator and makes it possible to create electricity. But it also serves to operate different pumps of the motor. If it ever breaks, the latter could make damages frankly important in the engine of this Renault Vel Satis.

A metallic noise on the Renault Vel Satis:

It's a noise that usually comes Cold. The most common source is that some of the streaks on this belt turn out to be damaged. But this can also happen in the case where the pulley is a little off-center. If the belt deteriorates, it could of course break. If you ever notice this noise, the best thing to do is to change the belt and the problem will be erased almost every time.

A sharp squeal on the Renault Vel Satis:

Indeed, it is the most common concern, as well as the least dramatic. It is usually made cold, but can come back when you drive from time to time. However, it suddenly stops. This problem is usually caused by the fact that the accessory belt is not tight enough. It will suffice tender and it's over. Small warning, in the event that it remains in this state for too long, the belt could be damaged and cause more serious concern in the long term. This sharp screeching also appears at times when the damper pulley is damaged, however it is rather rare.

A slight hiss or breath on the Renault Vel Satis:

It is the opposite of the preoccupation of before. Your belt is likely to be excessively tight or too small. You can imagine what you should do!

Alternator noise on a Renault Vel Satis

Assumed that it is indeed the alternator which creates this noise and not the belt, in this case the problems will be completely divergent. However, the noise you hear could be similar to that of a strap, either high hiss. The problem may arise from a electrical failure, this remains rather frequent. If ever voltage useful for the good activity of the Renault Vel Satis is low, it is generally seen in the lack of intensity of the indicator lights or bulbs inside the vehicle. If the lack of intensity is excessive, it is possible that the battery indicator can be running. So as to make a real diagnostic of your problem, it is quite feasible to use a voltmeter to check the tension on the + and - of the battery, with the ignition on of course. Assuming that the voltage is lower than that recommended on the battery, the concern could consequently come from the alternator. In this case, it should generally be changed.

Conclusion:

Alternator noise usually 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 a quote from a mechanic rather than starting work, since we are in no way sure of the source of the problem. We hope this post helped you, if so don't hesitate to post a comment. Enjoy the road with your Renault Vel Satis.
