You may already know this, however the alternator is a determining component within an engine. He himself is the one who guarantees to change energy of the engine block of your Toyota Hilux in Electricity supply in order to recharge the battery. If there is ever a problem, this could especially cause electrical failures. It is therefore crucial to pay attention to it. However, the problem could also come from the belt, and even pulleys. We will see through this post where will be able to come from problems according to the noise that you hear.
Noise alternator belt on a Toyota Hilux
La alternator belt, also called accessory belt, is the capital element which contributes to the proper functioning of the alternator. It is this one which, through its convolution, drives the alternator and will produce electricity. However, it also serves to rotate different pumps of the engine block. In case it breaks, it could make damages very serious in your engine of this Toyota Hilux.
A metallic noise on the Toyota Hilux:
It's a noise that often comes Cold. The most classic origin is that the streaks of this belt will be damaged. However, this could also occur if the pulley is a tantiner out of the gon. If the belt is ever released, it could of course break. If it happens that you recognize this sound, the best thing will be to replace the belt and the problem will be erased almost every time.
A sharp squeal on the Toyota Hilux:
Indeed, this is the most common hassle, as well as the least serious. It usually comes from cold, but may reappear even when hot sometimes. Nevertheless, it suddenly stops. This problem usually occurs when the accessory belt is not tight enough. Just the tender and voila. Warning, when it remains in this situation too long, the belt could be damaged and cause more serious concern in the long term. This sharp squeak also occurs at times when the damper pulley happens to be damaged, however it is rather rare.
A slight hiss or breath on the Toyota Hilux:
It's the opposite of the hassle before. The belt is probably too tight or too small. You know what you are going to have to do!
Alternator noise on a Toyota Hilux
When it is really the alternator which creates this sound and not the belt, in this situation the problems will be completely different. However, this sound may resemble that of a belt, so a high hiss. The problem could be caused by a electrical failure, it is relatively frequent. If ever voltage essential for the proper functioning of your Toyota Hilux remains deficient, this is generally related to the lack of power of the lights or lights within the vehicle. If the lack of power is obvious, it happens that the battery indicator stay on. So as to carry out a real diagnostic of the problem, it is still useful to use a voltmeter to check the tension on the plus and minus of its battery, the engine of course started. If the voltage is ever lower than that suggested by the battery, the problem could actually come from the alternator. In this case, it usually needs to be replaced.
Conclusion:
An alternator sound often comes from the alternator belt, but could also come from the alternator itself. Economically, an alternator belt is much cheaper compared to the alternator. Get a quote from a auto repairer before attempting work, because we are in no way assured of the cause of the problem. We hope that this post served you something, in this case do not hesitate to write a comment. Have a good trip with your Toyota Hilux.
