It may not be unknown to you, but the alternator is a vital component in an engine. This is the one who is responsible for changing energy of the engine block of this Volkswagen 411 in Electricity supply in order to recharge the battery. In the specific case where there is a malfunction, this can essentially cause electrical failures. It therefore seems essential to deal with it. However, the malfunction can also come from your belt, sometimes pulleys We will see through this post where will be able to come problems related to noise which is issued.noise-alternator-Volkswagen-411

Noise alternator belt on a Volkswagen 411

La alternator belt, also known as an accessory belt, proves to be the essential element which contributes to the proper functioning of the alternator. It is this one which by its convolution carries the alternator and allows to create electricity. But it also serves to rotate different pumps of the engine block. In the event that it destroys, the latter may make damages frankly important in the engine of the Volkswagen 411.

A metallic noise on the Volkswagen 411:

Here's a noise that usually comes Cold. The most common cause is that some of the streaks in the belt are damaged. But it can also happen if the pulley is very slightly offset. If the belt is damaged it can of course break. If you happen to hear this sound, it is best to replace the belt and the malfunction will be corrected almost without fail.

A sharp squeal on the Volkswagen 411:

Indeed, it is the most frequent concern, but also the least critical. It is usually issued cold, but may reappear when you drive from time to time. However, it suddenly disappears. This noise usually comes when the accessory belt is slack. It is necessary to tender and it's won. Warning, if it remains in this state for a long time, the belt could be damaged and cause a more dramatic problem at the end. This sharp screeching also appears at times when the damper pulley is deteriorated, but it is more rare.

A slight hiss or breath on the Volkswagen 411:

It is the opposite of the preoccupation of before. The belt is probably overly tight or too short. You can imagine what you have to do!

Alternator noise on a Volkswagen 411

When it is indeed the alternator which produces this sound and not your belt, then the malfunctions will be fundamentally singular. However, this emitted sound may have similarities to that of a belt, i.e. a high hiss. The malfunction may come from a electrical failure, it's pretty ordinary. If it happens that the voltage essential to the good activity of the Volkswagen 411 is deficient, it is usually seen in the lack of power of the indicator lights or bulbs inside the car. Assuming that the insufficient power is excessive, it happens that the battery indicator is on. In order to achieve a real diagnostic of your malfunction, it is entirely feasible to use a voltmeter to check the tension via the + and the minus of the battery, the ignition is on naturally. If the voltage turns out to be lower than that recommended on the battery, the malfunction can therefore come from the alternator. In this case, it usually needs to be replaced.

Conclusion:

A new alternator sound generally comes from the alternator belt, but may also come from the alternator itself. financially, an alternator belt is much cheaper compared to the alternator. Get a quote from a mechanic before starting work, simply because you are never sure of the source of the malfunction. Hoping that this post has been useful to you, in this case you can write a comment. Enjoy the road with your Volkswagen 411.
