You certainly suspect it, but the alternator is a fundamental element within an engine. This is the one that guarantees to change energy of the engine of this Volkswagen 1500 in Electricity supply so as to recharge the battery. If there is ever a malfunction, it can therefore mainly cause electrical failures. It is therefore essential to deal with it. However, the problem may also arise from the belt, or even pulleys. We will see in this post where will be able to come problems selon le noise which is issued.
Noise alternator belt on a Volkswagen 1500
La alternator belt, also called an accessory belt, is the essential component that contributes to the proper functioning of the alternator. It is it which, thanks to its rotation, drives the alternator and will allow electricity to be produced. However, it also serves to rotate other pumps of the motor. If destroyed, the latter can cause damages very important in the engine of the Volkswagen 1500.
A metallic noise on the Volkswagen 1500:
This is a noise that usually comes Cold. The most common cause is that some of the streaks in the belt turn out to be damaged. However, this could also occur in the case where the pulley is an offset skewer. If the belt ever deteriorates, it can obviously break. If it happens that you recognize this sound, the best thing to do is to replace the belt and the problem will be corrected almost without fail.
A sharp squeal on the Volkswagen 1500:
This remains the most recurrent, but also the least critical, hassle. It is usually made cold, but may reproduce when you drive from time to time. However, it suddenly disappears. This noise usually comes as soon as the accessory belt is relaxed. Just the tender and it's won. Be careful, if it remains in this situation for a long time, the belt can be damaged and cause a more serious incident in the long term. This sharp noise also occurs sometimes when the damper pulley is damaged, but it is rather rare.
A slight hiss or breath on the Volkswagen 1500:
It's the opposite of the hassle of the last example. The belt is probably far too tight or even too short. You can imagine what you should do!
Alternator noise on a Volkswagen 1500
Assumed that it is really the alternator that produces this sound and not your belt, therefore the hassle will be completely divergent. However, this sound that we hear can have similarities compared to that of a strap, i.e. a high hiss. The problem could come from a electrical failure, this remains fairly usual. In case the voltage necessary for the proper functioning of this Volkswagen 1500 is low, it is usually seen during a lack of intensity of the lights or bulbs in your automobile. If the intensity gap is out of the ordinary, it may be that the battery indicator can be in operation. In order to achieve a good diagnostic of this problem, it is possible to use a voltmeter and probe the tension on the plus and minus of the battery, with the ignition on of course. If the voltage is lower than that suggested by the battery, the problem can actually come from the alternator. So you usually need to replace it.
Conclusion:
A new alternator sound generally comes from the alternator belt, but may also come from the alternator itself. financially, an alternator belt costs relatively less than the alternator. Ask the price at a mechanic rather than embarking on work, as there is no guarantee of the source of the problem. We hope this guide has served you well, if so you can leave a comment. Have a good trip with your Volkswagen 1500.
