It may not be unknown to you, however the alternator is an essential part in an engine. It is this one that happens to be the guarantor of change energy of the engine of this Kia Optima in Electricity supply in order to recharge the battery. If there is a problem, it could essentially cause power outages. It is indeed essential to solve the problem. However, the concern could also come from your belt, or even pulleys.

Noise of the alternator belt on a Kia Optima
La alternator belt, also called the accessory belt, is the essential element which contributes to the good action of the alternator. It is the latter which by its convolution drives the alternator and provides the means to produce electricity. However, it is also used at the same time to operate other pumps of the motor. If it breaks, the latter may cause damages very important in the engine of the Kia Optima.
A metallic noise on the Kia Optima:
This is a noise that usually comes Cold. The most common reason is that part of the ridges on the belt turn out to be damaged. However, this can also happen if the pulley is slightly off-center. If ever the belt deteriorates it could of course break. If you ever hear this noise, the best thing you can do is replace the belt and the problem is almost guaranteed to be gone.

Alternator noise on a Kia Optima
Assuming it is the alternator that is making this noise and not your belt, then the problems are going to be fundamentally different. However, this noise that you hear may have some resemblance to that of a belt, which means a high hiss. The problem may arise from a electrical failure, this remains quite frequent. In case the voltage essential for the proper functioning of your Kia Optima is insufficient, this is usually reflected in the lack of power of the warning lights or bulbs within the car. Assuming that the lack of power is unusual, it is possible that the battery indicator stay on. If you want to do a real diagnostic of the problem, it is useful to use a voltmeter in order to take the tension via the plus and minus of your battery, with the engine running of course. If ever the voltage is found to be lower than that recommended by the battery, the problem may in fact come from the alternator. In this case, it usually needs to be replaced.

A new alternator noise generally comes from the alternator belt, but can also come from the alternator itself. Economically, the alternator belt costs much less than the alternator.
