As you can probably imagine, the alternator is a vital component in an engine. It is he himself who happens to be the guarantor of change energy of the engine block of your Renault Scenic 3 Xmod in Electricity supply in order to recharge the battery. If ever there is a problem, it can cause mainly electrical failures. It therefore seems essential to pay attention to it. However, the dysfunction can mainly come from its belt, and even pulleys. Thanks to this guide, we will discover where the problems according to the noise that you hear.noise-alternator-Renault-Scenic-3-Xmod

Noise of the alternator belt on a Renault Scenic 3 Xmod

La alternator belt, also called the accessory belt, is the essential element that contributes to the proper functioning of the alternator. It is the latter which, via its rotation, carries the alternator and will make it possible to manufacture electricity. However, this is also used to operate other pumps of the engine block. In the event that it breaks, the latter could cause damages very serious in your engine of the Renault Scenic 3 Xmod.

A metallic noise on the Renault Scenic 3 Xmod:

This is a hazard that often comes Cold. The most common cause is that the ridges in the belt will be damaged. However, it could also happen if the pulley is slightly off-center. If the belt ever deteriorates it could obviously break. If you ever see this noise, the ideal is to replace the belt and the malfunction will be corrected almost every time.

A sharp squeal on the Renault Scenic 3 Xmod:

Indeed, it is the most recurring problem, but also the least dramatic. It is usually issued cold, but will occasionally reappear when you are driving at times. However, it stops abruptly. This inconvenience usually arises when the accessory belt is not tensioned enough. It will be enough to tender and it's won. Warning, when it remains in this state too long, the belt could be damaged and cause a more serious problem in the long term.

A slight hiss or breath on the Renault Scenic 3 Xmod:

This is the opposite of the previous problem. The belt is probably too tight or too short. You can imagine what you have to do!

Alternator noise on a Renault Scenic 3 Xmod

In the event that it is the alternator that makes the noise and not the belt, then the problems will be really divergent. However, the noise emitted could have similarities to that of a belt, so a high hiss. The dysfunction will sometimes come from a electrical failure, this is still quite common. If ever voltage essential to the good activity of this Renault Scenic 3 Xmod is usually weak, this is usually seen in the lack of intensity of the warning lights or bulbs within the car. If the insufficient intensity is unusual, it happens that the battery indicator stay on. If you wish to proceed with a voucher diagnostic malfunction, it is entirely feasible to use a voltmeter and probe the tension via the plus and minus of the battery, with the ignition on of course. Assuming that the voltage is lower than that recommended on the battery, the malfunction may in fact come from the alternator. In this specific case, it will usually need to be replaced.

Conclusion:

An alternator noise often comes from the alternator belt, but will sometimes also come from the alternator itself. Economically, the alternator belt costs much less than the alternator. Have a costing done at a mechanic before attempting repairs, quite simply because we are in no way certain of the origin of the malfunction. We hope this guide has helped you, in which case you can leave a comment. Enjoy the road with your Renault Scenic 3 Xmod.
