You certainly suspect it, however the alternator is a crucial element within an engine. It is this one that is responsible for changing energy of the engine of this Smart For-us in Electricity supply so as to recharge the battery. In the specific case where there is a concern, it can thus generate most of the electrical failures. It is therefore crucial to deal with it. However, the problem may also arise from its belt, sometimes pulleys. Thanks to this guide, we will see where the problems related to noise that you hear.
Alternator belt noise on a Smart For-us
La alternator belt, also called accessory belt, is the capital element which contributes to the proper functioning of the alternator. It is the latter which, via its rotation, drives the alternator and makes it possible to produce electricity. However, it also serves to operate different pumps of the motor. In the event that it destroys, it could cause damages truly serious within the engine of this Smart For-us.
A metallic noise on the Smart For-us:
It is a hazard that generally arises Cold. The most common cause is that the streaks on this belt will be damaged. However, this can also happen when the pulley is slightly out of the gon. In case the belt deteriorates it could of course break. If you recognize this sound, it is best to replace the belt and the problem will be solved almost without fail.
A sharp screech on the Smart For-us:
Indeed, it is the most recurrent dysfunction, but also the least serious. It generally comes from cold, but could return even hot at times. However, it suddenly stops. This inconvenience generally comes when the accessory belt is slack. It will suffice tighten and voila. Small warning, in the event that it remains in this state for too long, the belt could deteriorate and cause a more serious dysfunction in the long term. This sharp noise also appears at times in the event that the damper pulley is damaged, however it is less frequent.
A slight hiss or breath on the Smart For-us:
It is the opposite of the previous dysfunction. Your belt is certainly far too tight or even too small. You can imagine what you are going to have to do!
Alternator noise on a Smart For-us
If it is indeed the alternator that creates this sound and not the belt, then the hassle will be totally different. However, the sound you hear may be similar to that of a strap, either high hiss. The malfunction could come from a electrical failure, it is relatively frequent. In case the voltage essential to the good activity of your Smart For-us is low, it is generally seen during a lack of alertness of the lights or bulbs within the car. If the lack of alertness is excessive, it happens that the battery indicator is on. In order to make a real diagnostic of your malfunction, it is useful to use a voltmeter and check the tension on the + and minus of your battery, the ignition on of course. Assuming that the voltage is less than that recommended by the battery, the problem could therefore come from the alternator. In this specific case, it will generally have to be replaced.
Conclusion:
A new alternator sound usually comes from the alternator belt, but could also come from the alternator itself. financially, an alternator belt is much cheaper than the alternator. Have a costing done at a mechanic before starting repairs, because you can never be sure of the source of the problem. Hoping that this text has helped you, if so we invite you to write a comment. Have a good ride with your Smart For-us.
