You can imagine it, but the alternator is a determining element in an engine. He is the one who is responsible for transforming energy the engine of your Toyota Previa 2 in Electricity supply in order to recharge the battery. If there is ever a problem, it could therefore essentially cause electrical failures. It is therefore essential to pay attention to it. Only, the dysfunction could mainly come from its belt, and even pulleys. We will find out through this post where the problems related to noise that comes out.noise-alternator-Toyota-Previa-2

Noise of the alternator belt on a Toyota Previa 2

La alternator belt, also called accessory belt, is the essential component that contributes to the proper functioning of the alternator. It is he who, by its convolution, wins the alternator and will give the means to create electricity. However, it also serves to operate other pumps of the motor. If it breaks, it can make damages frankly serious in the engine of the Toyota Previa 2.

A metallic noise on the Toyota Previa 2:

This is a hazard that generally comes Cold. The most common cause is that the streaks in the belt have deteriorated. However, it could also happen if the pulley is slightly out of the gon. If the belt falls apart it can of course break. If you ever identify this noise, it is best to replace the belt and the malfunction will be solved almost every time.

A sharp squeal on the Toyota Previa 2:

It is the most ordinary concern, but also the least serious. It usually comes from cold, but could reappear even when hot sometimes. However, it suddenly stops. This inconvenience generally comes from when the accessory belt is not tight enough. It will suffice tighten and it's done. Be careful, in the event that it remains in this situation for too long, the belt may be damaged and cause a more serious incident at the end.

Alternator noise on a Toyota Previa 2

In the event that it is indeed the alternator which produces this noise and not the belt, in this situation the problems will be entirely different. However, the noise you hear may have similarities compared to that of a strap, either high hiss. The malfunction could arise from a electrical failure, this remains rather ordinary. If it happens that the voltage essential to the good activity of your Toyota Previa 2 is insufficient, it is generally seen during a lack of alertness of the indicator lights or lights in the car. If the lack of alertness is evident, it is possible that the battery indicator either running. In order to carry out a real diagnostic of the malfunction, it is still possible to use a voltmeter to probe the tension on the plus and minus of its battery, with the engine running naturally. If the voltage is lower than that recommended on the battery, the malfunction may actually come from the alternator. In this case, it usually needs to be replaced.

Conclusion:

Alternator noise generally comes from the alternator belt, but could also come from the alternator itself. financially, the alternator belt costs much less compared to the alternator.
