As you can imagine, the alternator is a crucial element within an engine. He is the one who guarantees to change energy of the engine of this Toyota Previa in Electricity supply so as to recharge the battery. If there is a malfunction, it could consequently cause most of the electrical breakdowns. It therefore seems important to resolve the problem.

Noise alternator belt on a Toyota Previa

La alternator belt, also called accessory belt, is the essential element which contributes to the good action of the alternator. It is the latter which, through its convolution, drives the alternator and will provide the means to produce electricity. However, it also serves to rotate different pumps of the motor. In the event that it breaks, the latter may make damages very serious in the engine of the Toyota Previa.

A metallic noise on the Toyota Previa:

Here is a hazard that often comes Cold. The most classic origin is that the streaks of the belt will be damaged. However, it can also happen as soon as the pulley is slightly out of the gon. In case the belt is damaged it can obviously break. If you recognize this sound, the ideal is to change the belt and the problem will be solved almost every time.

A slight hiss or breath on the Toyota Previa:

It is the opposite of the dysfunction of the last example. Your strap is likely to be excessively tight or too short. You know what you have left to do !

Alternator noise on a Toyota Previa

When it is indeed the alternator that makes the sound and not your belt, in this case the problems are fundamentally singular. However, the sound you hear may have similarities compared to that of a strap, so a high hiss. The problem will sometimes arise from electrical failure, this remains quite frequent. If it happens that the voltage essential for the good activity of the Toyota Previa is usually weak, it is often seen during a power failure of the indicator lights or lights inside your automobile. Assuming that the power deficiency is excessive, it may be that the battery indicator can be turned on. In order to achieve a real diagnostic of your problem, it is quite feasible to use a voltmeter to check the tension via the + and the least of its battery, the engine obviously started. If the voltage is found to be lower than that recommended on the battery, the problem will actually come from the alternator. So generally you have to change it.

Conclusion:

A new alternator sound often comes from the alternator belt, but will sometimes also come from the alternator itself. financially, an alternator belt is much cheaper compared to the alternator.
