You may already know this, however the alternator is a fundamental element in an engine. He is the one who guarantees to change energy of the engine block of your Toyota Land Cruiser Serie 120 in Electricity supply so as to recharge the battery. If there is a problem, it can mainly cause electrical failures. It is therefore crucial to pay attention to it. However, the problem may also come from your belt, or even pulleys. We will see in this post where will be able to come from problems selon le noise that comes out.
Noise of the alternator belt on a Toyota Land Cruiser Serie 120
La alternator belt, also called accessory belt, is the essential element that contributes to the proper functioning of the alternator. It is the latter which by its rotation drives the alternator and makes it possible to produce electricity. But it also serves to rotate different pumps of the engine block. In the event that it destroys, the latter could cause damages really important in the engine of the Toyota Land Cruiser Serie 120.
A metallic noise on the Toyota Land Cruiser Serie 120:
Here is a noise that usually comes Cold. The most common source is that some of the streaks in the belt have deteriorated. But it can also occur if the pulley is very slightly offset. If the belt falls apart it could of course break. If you ever notice this noise, the ideal will be to change the belt and the problem will be corrected almost every time.
A sharp squeal on the Toyota Land Cruiser Serie 120:
Indeed, it is the most frequent problem, as well as the least dramatic. It usually comes from cold, but could recur when you drive from time to time. However, it stops instantly. This problem usually occurs when the accessory belt is not tight enough. All you need is tender and it's over. Be careful, when it stays in this situation for a long time, the belt could deteriorate and cause a more dramatic problem in the long term. This sharp squeak also occurs sometimes when the damper pulley happens to be deteriorated, however it is rather rare.
A slight hiss or breath on the Toyota Land Cruiser Serie 120:
It is the opposite of the problem of the last example. The belt is probably too tight or too short. You imagine what you must do!
Alternator noise on a Toyota Land Cruiser Serie 120
Assumed that it is indeed the alternator that makes noise and not the belt, in this situation the concerns will be totally different. However, the noise emitted could have similarities to that of a belt, a high hiss. The concern could come from a electrical failure, this remains fairly ordinary. If it happens that the voltage useful for the good activity of the Toyota Land Cruiser Serie 120 is usually weak, it is generally seen in the lack of intensity of the lights or lights inside the car. If the intensity intensity is out of the ordinary, it happens that the battery indicator either running. So as to achieve a good diagnostic of this concern, it is quite feasible to use a voltmeter to check the tension via the plus and the - of its battery, the engine running of course. If the voltage is ever lower than that recommended on the battery, the problem could therefore come from the alternator. In this case, you usually need to change it.
Conclusion:
Alternator noise usually comes from the alternator belt, but could also come from the alternator itself. financially, an alternator belt is much cheaper than the alternator. Have a costing done at a mechanic rather than starting work, simply because we are in no way certain of the source of the problem. Hoping that this text has served you something, if so do not hesitate to leave a comment. See you soon with your Toyota Land Cruiser Serie 120.
