La alternator belt, also referred to as the accessory belt, turns out to be the essential element which contributes to the good action of the alternator.

In the event that it destroys, the latter may cause damages frankly serious in your seat leon engine.
A metallic noise on the seat leon:
It’s a noise that usually comes Cold. The most common cause is that some of the ridges in the belt turn out to be damaged. However, this can also happen if the pulley is slightly off-center. If the belt breaks, it can obviously break. If you ever recognize this noise, it is best to change the belt and the malfunction will be repaired almost every time.

Alternator noise on a Seat Leon
When it is indeed the alternator which produces this noise and not your belt, in this case the malfunctions are totally divergent. However, this noise that you hear may have some similarities compared to that of a belt, that is to say a high hiss. The problem may come from electrical failure, it is quite usual. If it happens that the voltage essential to the good activity of the seat leon is usually weak, this is usually noticed in the lack of power of the warning lights or bulbs inside the vehicle. If ever the insufficient power is out of the ordinary, it happens that the battery indicator can be running. In order to achieve real diagnostic of your problem, it is helpful to use a voltmeter and take the tension on the + and - of your battery, with the ignition on naturally. Assuming that the voltage turns out to be lower than that recommended on the battery, the malfunction could therefore come from the alternator. In this situation, it will usually need to be changed.
