It may not be unknown to you, however the alternator is a fundamental component in an engine. He himself is responsible for transforming energy of the engine block of your Toyota Avensis 4 in Electricity supply so as to recharge the battery. In the specific case where there is a malfunction, this can usually cause electrical failures. It therefore seems important to pay attention to it. Only the problem can also come from your belt, and even pulleys. We will see through this guide where will be able to come from problems according to the noise that you hear.

La alternator belt, also called accessories belt, happens to be the essential element that contributes to the proper functioning of the alternator. It is the latter which, through its convolution, carries the alternator and creates electricity. However, it also serves to spin others pumps of the engine block. If it breaks, it will be able to make damages rather important within the engine of this Toyota Avensis 4.
A metallic noise on the Toyota Avensis 4:
Here's a noise that usually comes Cold. The most classic origin is that part of the streaks of this belt are damaged. However, this can also happen when the pulley is slightly out of the gon. If the belt deteriorates, it could obviously break. If you recognize this noise, it is best to change the belt and the problem will be corrected almost every time.

Alternator noise on a Toyota Avensis 4
When it is indeed the alternator which produces this noise and not the belt, then the malfunctions will be totally divergent. However, the noise we hear may have similarities compared to that of a belt, i.e. high hiss. The concern could come from a electrical failure, it's relatively ordinary. In case the voltage necessary for the proper activity of your Toyota Avensis 4 remains insufficient, it usually shows during a lack of intensity of the lights or bulbs inside your automobile. If the insufficient intensity is evident, it is possible that the battery indicator either running. In order to achieve a good diagnostic worry, it is entirely feasible to use a voltmeter to probe the tension on the + and minus of your battery, the ignition on of course. Assuming that the voltage is lower than that recommended by the battery, the problem will actually come from the alternator. In this situation, it will usually need to be changed.
Conclusion:
Alternator noise generally comes from the alternator belt, but could also come from the alternator itself. financially, an alternator belt is relatively cheaper compared to the alternator.
