It may not be unknown to you, but the alternator is a fundamental component within an engine. It is himself who is responsible for transforming energy of the engine of this Renault Trafic 3 Combi in Electricity supply in order to recharge the battery. If ever there is a malfunction, it can cause especially electrical failures. It is therefore important to deal with it. Only, the concern can also come from your belt, and even pulleys. We will discover through this post where the problems according to the noise that you hear.noise-alternator-Renault-Trafic-3-Combi

Noise of the alternator belt on a Renault Trafic 3 Combi

La alternator belt, also called an accessory belt, proves to be the essential component which contributes to the proper functioning of the alternator. It is this one which thanks to its rotation drives the alternator and makes it possible to produce electricity. However, it also serves to train others pumps of the motor. If it breaks, it can cause damages really important in your engine of this Renault Trafic 3 Combi.

A metallic noise on the Renault Trafic 3 Combi:

This is a noise that generally comes Cold. The most common reason is that some of the streaks on this belt have deteriorated. However, this can also happen when the pulley is slightly offset. If the belt breaks up, it can obviously break. If you distinguish this noise, the ideal is to change the belt and the problem will be solved almost without fail.

A sharp squeal on the Renault Trafic 3 Combi:

This remains the most common problem, as well as the least important. It usually comes cold, but can come back when you are driving sometimes. However, it suddenly disappears. This inconvenience generally comes in the case where the accessory belt is not tight enough. It will suffice tighten and voila. Small warning, when it remains in this state for too long, the belt may deteriorate and cause a more dramatic problem over time. This sharp noise also occurs sometimes when the damper pulley is damaged, but it is rather rare.

A slight hiss or breath on the Renault Trafic 3 Combi:

It is the opposite of the problem of the last example. Your strap is certainly far too tight or too small. You can imagine what you are going to have to do!

Alternator noise on a Renault Trafic 3 Combi

When it is indeed the alternator which produces this noise and not the belt, in this situation the concerns will be really different. However, the noise emitted may have similarities compared to that of a belt, so a high hiss. The problem may arise from a electrical failure, this remains rather usual. If ever voltage paramount to the good activity of your Renault Trafic 3 Combi is insufficient, it is generally seen during a lack of power of the indicator lights or lights in your automobile. If the insufficient power is out of the ordinary, it happens that the battery indicator can be in operation. So as to make a good diagnostic of your problem, it remains entirely feasible to use a voltmeter in order to take the tension on the + and minus of the battery, the ignition on of course. Assuming that the voltage turns out to be lower than that recommended by the battery, the problem will consequently come from the alternator. In this situation, it usually needs to be changed.

Conclusion:

Alternator noise generally comes from the alternator belt, but can also come from the alternator itself. Economically, an alternator belt is much cheaper than the alternator. Ask the price at a mechanic before starting repairs, as you can never be sure of the source of the problem. We hope this guide has helped you, if so we invite you to post a comment. Enjoy the road with your Renault Trafic 3 Combi.
