You may already know this, but the alternator is a critical component in an engine. It is he himself who is responsible for transforming energy of the engine block of this Toyota Highlander 2 in Electricity supply so as to recharge the battery. If ever there is a problem, it could in fact cause mainly electrical failures. It is indeed essential to pay attention to it. However, the concern could mainly come from its belt, and even pulleys. We will see in this post where can come from problems related to noise that comes out.noise-alternator-Toyota-Highlander-2

Noise of the alternator belt on a Toyota Corolla

La alternator belt, also called the accessory belt, turns out to be the most important component involved in the proper functioning of the alternator. It is this one which through its convolution carries the alternator and will allow electricity to be produced. However, this is also used to operate other pumps of the engine block. In the event that it breaks, it could cause damages frankly important within the engine of the Toyota Highlander 2.

A metallic noise on the Toyota Highlander 2:

This is a noise that usually comes Cold. The most common cause is that part of the ridges on the belt are damaged. However, this could also occur when the pulley is a little out of axis. If the belt ever breaks it could of course break. If you recognize this sound, it is best to change the belt and the problem will be corrected almost every time.

A high-pitched screech on the Toyota Highlander 2:

Indeed, it is the most usual concern, but also the least critical. It often comes cold, but can come back when you are driving every now and then. However, it stops instantly. This problem often occurs when the accessory belt is not tight enough. Just the tighten and voila. Be careful, if it remains in this state for too long, the belt could be damaged and cause a more serious problem in the long term. This sharp squealing also occurs at times in the event that the damper pulley is damaged, however it is less common.

A slight whistling or hissing sound on the Toyota Corolla:

This is the opposite of the previous concern. The belt is certainly too tight or too small. You can imagine what you have to do!

Alternator noise on a Toyota Corolla

When it is indeed the alternator which produces this sound and not your belt, then the concerns will be completely different. However, the sound we hear could have similarities compared to that of a belt, so a high hiss. The concern may arise from a electrical failure, this remains relatively frequent. If it happens that the voltage necessary for the good activity of the Toyota Highlander 2 is weak, this is often noticed in the lack of liveliness of the lights or bulbs within the car. If ever the lack of liveliness is unusual, it may be that the battery indicator stay on. If you want to make a real diagnostic of this concern, it remains quite feasible to use a voltmeter and to check the tension via the plus and minus of your battery, with the engine running of course. If ever the voltage turns out to be lower than that recommended on the battery, the problem can therefore come from the alternator. In this case, it usually needs to be changed.

Conclusion:

An alternator sound usually comes from the alternator belt, but can also come from the alternator itself. financially, the alternator belt is much cheaper than the alternator. Request a quote from a auto repairer rather than starting work, quite simply because we are in no way certain of the cause of the problem. Hoping that this post has served you for something, if this is the case we invite you to post a comment. Have a good trip with your Toyota Highlander 2.
