Noise of the alternator belt on a Toyota Corolla

La alternator belt, also called the accessory belt, is the essential component which contributes to the good action of the alternator. It is this which, thanks to its rotation, drives the alternator and makes it possible to manufacture electricity. But it is also used to train different pumps of the engine block. If it breaks, the latter could make damages frankly important in the engine of the Toyota Yaris 2 Ts.

A metallic noise on the Toyota Yaris 2 Ts:

Here is a hazard that generally comes Cold. The most common cause is that the ridges in the belt will be damaged. But that could also happen if the pulley is a stick out of gon. If the belt gets damaged it could of course break. If it happens that 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 Corolla

When it is really the alternator which creates this noise and not the belt, then the malfunctions will be really singular. Nevertheless, the noise emitted could have similarities compared to that of a belt, that is to say a high hiss. The problem could come from a electrical failure, it's pretty ordinary. In case the voltage essential for the proper functioning of this Toyota Yaris 2 Ts is insufficient, this is generally indicated by the lack of intensity of the warning lights or bulbs inside your automobile. If ever the intensity squaring is excessive, it is possible that the battery indicator stays on. In order to make a real diagnostic of your problem, it is still possible to use a voltmeter and check the tension on the + and the minus of its battery, with the ignition obviously on. If the voltage is lower than that recommended on the battery, the problem could therefore come from the alternator. In this situation, you usually need to change it.

Conclusion:

A new alternator noise usually comes from the alternator belt, but could also come from the alternator itself. Economically, an alternator belt is relatively cheaper compared to the alternator.
