It may not be unknown to you, but the alternator is a fundamental component in an engine. He is the one who guarantees to transform energy from the engine block of your Toyota Hilux 4 in Electricity supply so as to recharge the battery. If there is ever a malfunction, it could therefore essentially cause electrical failures. It is therefore essential to deal with it. However, the malfunction could also come from the belt, sometimes pulleys. We will see through this article where will be able to come problems selon le noise which is issued.
Noise alternator belt on a Toyota Hilux 4
La alternator belt, also called accessory belt, is the essential element that contributes to the proper functioning of the alternator. It is this which, via its convolution, carries the alternator and will make it possible to create electricity. But it also serves to operate different pumps of the engine block. In the event that it destroys, it may make damages really important in the engine of the Toyota Hilux 4.
A metallic noise on the Toyota Hilux 4:
This is a noise that usually comes Cold. The most common cause is that the streaks in the belt turn out to be damaged. But it could also occur when the pulley is slightly offset. If the belt gets damaged, it can of course break. If you recognize this sound, the ideal thing is to replace the belt and the malfunction will be repaired almost without fail.
A sharp squeal on the Toyota Hilux 4:
Indeed, it is the most ordinary dysfunction, but also the least important. It usually comes from cold, but will sometimes reproduce even when hot from time to time. However, it suddenly disappears. This inconvenience generally comes as soon as the accessory belt is not tight enough. All you need is tighten and voila. Be careful, if it remains in this state for too long, the belt could be damaged and cause a more serious incident at the end. This sharp screeching also occurs at times when the damper pulley happens to be damaged, but it's less common.
A slight hiss or breath on the Toyota Hilux 4:
It is the opposite of the dysfunction of the last example. Your belt is probably far too tight or even too short. You can imagine what you are going to have to do!
Alternator noise on a Toyota Hilux 4
In the event that it is indeed the alternator which makes sound and not the belt, in this situation the malfunctions will be really divergent. However, this sound you hear may have similarities compared to that of a strap, a high hiss. The problem will sometimes arise from electrical failure, this remains relatively ordinary. In case the voltage essential for the proper functioning of the Toyota Hilux 4 is weak, it is generally seen in the lack of power of the lights or lights inside the car. If the lack of power is excessive, it happens that the battery indicator can be running. In order to proceed with a good diagnostic of the problem, it is useful to use a voltmeter in order to take the tension via the + and the least of its battery, the engine started of course. If the voltage is found to be lower than that recommended on the battery, the malfunction may in fact come from the alternator. In this situation, it will generally be necessary to replace it.
Conclusion:
A new alternator sound generally comes from the alternator belt, but will sometimes also come from the alternator itself. Economically, the alternator belt is relatively cheaper than the alternator. Ask for an estimate at a mechanic rather than embarking on work, because you can never be sure of the source of the malfunction. We hope this post helped you, in this case we invite you to leave a comment. Enjoy the road with your Toyota Hilux 4.
