You may already know this, but the alternator is a vital component within an engine. He is the one who is responsible for changing energy of the engine block of this Kia Optima 2 in Electricity supply in order to recharge the battery. In the specific case where there is a problem, it can usually lead to electrical failures. It therefore seems essential to pay attention to it. However, the problem can also be caused by your belt, or even pulleys. We will see in this article where the problems related to noise that comes out.noise-alternator-Kia-Optima-2

Noise of the alternator belt on a Kia Optima

La alternator belt, also known as the accessory belt, is the essential component which participates in the good action of the alternator. This is the one which, via its rotation, carries the alternator and creates electricity. However, it is also used to turn other pumps of the engine block. If it breaks, it can cause damages frankly important in the engine of the Kia Optima 2.

A metallic noise on the Kia Optima 2:

Here is a noise that generally comes Cold. The most common reason is that part of the ridges on the belt have deteriorated. However, this can also happen when the pulley is slightly out of gon. If the belt ever deteriorates, it can naturally break. If it happens that you recognize this sound, the ideal is to change the belt and the malfunction will be fixed almost every time.

A shrill screeching noise on the Kia Optima 2:

This is the most common problem, but also the least critical. It is generally cold grown, but may come back when you sometimes drive. On the other hand, it stops promptly. This problem usually arises when the accessory belt is slack. All you need to do is tender and voila. Be careful, when it stays in this situation for too long, the belt can get damaged and eventually cause a more serious problem. This sharp noise sometimes also appears in the event that the damper pulley is damaged, but it is less common.

A slight whistling or hissing noise on the Kia Optima 2:

This is the opposite of the problem in the last example. Your belt is probably too tight or too small. You can imagine what to do!

Alternator noise on a Kia Optima 2

Suppose it is really the alternator that makes this sound and not the belt, in this case the malfunctions are completely different. However, this sound that you hear may have some similarities compared to that of a belt, that is to say a high hiss. The malfunction may result from a electrical failure, it is quite usual. If it happens that the voltage useful for the proper functioning of the Kia Optima 2 is usually weak, it can usually be seen from the lack of intensity of the warning lights or bulbs within the vehicle. If the lack of intensity is excessive, it happens that the battery indicator stays in operation. If you want to do a real diagnostic of this malfunction, it is still possible to use a voltmeter and to probe the tension on the plus and minus of your battery, the engine running of course. If the voltage is lower than that recommended by the battery, the malfunction will therefore come from the alternator. So it usually needs to be changed.

Conclusion:

A new alternator sound usually comes from the alternator belt, but can also come from the alternator itself. Economically, the alternator belt costs considerably less compared to the alternator. Ask for an estimate at a auto repairer rather than launching yourself into work, quite simply because you can never be sure of the origin of the dysfunction. Hope this article has helped you, if so you can post a comment. Have a good trip with your Kia Optima 2.
