It may not be unknown to you, however the alternator is an essential element in an engine. He is responsible for transforming energy the engine of your Smart Fortwo 3 in Electricity supply in order to recharge the battery. If there is ever a problem, it can essentially cause electrical failures. It therefore remains important to resolve the problem. However, the problem may also arise from its belt, and even pulleys. We will see through this article where the problems selon le noise that you hear.
Alternator belt noise on a Smart Fortwo 3
La alternator belt, also known as an accessory belt, is the essential element which contributes to the proper functioning of the alternator. It is this which, through its rotation, drives the alternator and makes it possible to produce electricity. However, it also serves to operate other pumps of the motor. If it destroys, it could cause damages rather serious in the engine of this Smart Fortwo 3.
A metallic noise on the Smart Fortwo 3:
It's a noise that usually comes Cold. The most common source is that the streaks on this belt turn out to be damaged. However, this can also happen when the pulley is slightly out of the gon. In the event that the belt is stretched, it could obviously break. If it happens that you identify this sound, the ideal will be to change the belt and the problem will be repaired almost every time.

Alternator noise on a Smart Fortwo 3
Assumed that it is really the alternator which produces this sound and not the belt, in this case the problems will be found to be totally singular. However, this sound you hear may be similar to that of a strap, which means a high hiss. The concern could come from a electrical failure, this is quite common. In case the voltage essential for the proper functioning of this Smart Fortwo 3 is usually deficient, it is often seen during a lack of intensity of lights or bulbs in your automobile. If the intensity intensity is out of the ordinary, it happens that the battery indicator is on. In order to make a real diagnostic of this concern, it is useful to use a voltmeter in order to check the tension via the + and the minus of the battery, the ignition works naturally. Assuming that the voltage is lower than that recommended by the battery, the problem could therefore come from the alternator. In this case, you usually need to change it.
Conclusion:
A new alternator sound generally comes from the alternator belt, but could also come from the alternator itself. Economically, an alternator belt costs relatively less than the alternator. Get the price from a auto repairer rather than starting work, since we are not necessarily sure of the source of the problem. We hope this article has served you something, in this case do not hesitate to post a comment. Have a good ride with your Smart Fortwo 3.
