Noise of the alternator belt on a Renault Trafic 3

La alternator belt, also called accessory belt, happens to be the capital element which contributes to the good action of the alternator. It is the latter which, via its rotation, drives the alternator and will make it possible to produce electricity. However, it also serves to rotate different pumps of the engine block. If it breaks, it could cause damages frankly serious in your engine of this Renault Trafic 3.

A metallic noise on the Renault Trafic 3:

This is a hazard that generally comes Cold. The most common reason is that the streaks on this belt have deteriorated. However it can also happen if the pulley is a tantiner out of gon. In case the belt gets damaged it could obviously break. If it happens that you identify this noise, it is best to change the belt and the problem will be corrected almost every time.

It is the opposite of the dysfunction of before. The belt is probably excessively tight or even too small. You know what you are going to have to do!

Alternator noise on a Renault Trafic 3

When it is really the alternator that is making noise and not your belt, then the hassle will be found to be quite divergent. However, the noise emitted could have similarities to that of a belt, i.e. high hiss. The concern can arise from a electrical failure, it is quite usual. If ever voltage necessary for the proper functioning of the Renault Trafic 3 is insufficient, it is usually seen during a power failure of the indicator lights or bulbs in your automobile. If the power gap is excessive, it happens that the battery indicator can be running. In order to make a real diagnostic of your concern, it is useful to use a voltmeter in order to probe the tension via the + and the least of its battery, with the engine running of course. If the voltage is ever lower than that recommended on the battery, the problem could actually come from the alternator. So, in general, it must be changed.

Conclusion:

A new alternator noise generally comes from the alternator belt, but can also come from the alternator itself. Economically, an alternator belt is much cheaper compared to the alternator.
