It may not be unknown to you, however the alternator is a critical component in an engine. It is he who happens to be responsible for changing energy of the engine block of your Volkswagen 181 in Electricity supply in order to recharge the battery. If there is a problem, then it could mainly lead to power outages. So it's important to fix the problem. However, the problem could also stem from the belt, sometimes pulleys. We will see through this post where will be able to come from problems according to the noise that you hear.noise-alternator-Volkswagen-181

Noise alternator belt on a Volkswagen 181

La alternator belt, also called the accessory belt, happens to be the most important component which contributes to the good action of the alternator. It is this one which, through its convolution, drives the alternator and will make it possible to create electricity. But it is also used to operate other pumps of the engine block. If she breaks, she can make damages rather important in the engine of the Volkswagen 181.

A metallic noise on the Volkswagen 181:

It’s usually a noise Cold. The most common source is that some of the ridges on the belt turn out to be damaged. But it could also happen when the pulley is out of gon a little bit. If ever the belt breaks, it could obviously break. If you recognize this sound, the best thing you can do will be to change the belt and the problem will almost certainly be fixed.

A sharp squeal on the Volkswagen 181:

It is the most common problem, and the least serious. It usually comes from cold, but could reappear even when hot from time to time. However, it suddenly disappears. This problem usually occurs when the accessory belt is not tight enough. It will suffice to tighten and it's won. Be careful, when it remains in this state for too long, the belt may deteriorate and eventually lead to a more serious malfunction. This high-pitched noise also occurs sometimes when the damper pulley is damaged, however it is rather rare.

A slight hiss or breath on the Volkswagen 181:

This is the opposite of the previous problem. The belt is probably too tight or too short. Can you imagine what you have to do!

Alternator noise on a Volkswagen 181

When it is indeed the alternator which makes the sound and not your belt, in this case the problems will be really different. However, this sound emitted may have similarities compared to that of a belt, so a high hiss. The concern could arise from a electrical failure, this remains fairly common. If ever voltage primordial for the proper functioning of this Volkswagen 181 remains insufficient, this is generally noticed when the lights or bulbs in your automobile are dimmed. Assuming the lack of intensity is evident, the battery indicator can be turned on. In order to make a real diagnostic worry, it is still quite feasible to use a voltmeter to take the tension on the + and the minus of your battery, with the ignition on of course. If the voltage is found to be lower than that recommended by the battery, the problem may therefore come from the alternator. In this case, it will generally have to be changed.

Conclusion:

A new alternator sound usually comes from the alternator belt, but could also come from the alternator itself. financially, an alternator belt costs considerably less compared to the alternator. Ask for an estimate at a mechanic rather than attempting repairs, because we are not necessarily certain of the source of the problem. Hope this guide has helped you, in that case you can post a comment. Enjoy the road with your Volkswagen 181.
