It may not be unknown to you, but the alternator is an essential component within an engine. This is the one who is responsible for changing energy of the engine block of your Volvo 340 in Electricity supply in order to recharge the battery. In the specific case where there is a problem, it could therefore mainly cause electrical failures. It is therefore important to resolve the problem. Only, the concern could mainly come from your belt, or even pulleys. We will find out through this post where the problems selon le noise which is issued.noise-alternator Volvo-340

Noise alternator belt on a Volvo 340

La alternator belt, also called accessory belt, is the essential element that contributes to the good action of the alternator. It is this which, thanks to its convolution, drives the alternator and will provide the means to produce electricity. However, it also serves to operate different pumps of the engine block. In the event that it breaks, it could cause damages really important in the engine of the Volvo 340.

A metallic noise on the Volvo 340:

It is a hazard 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 happen when the pulley is slightly out of the gon. If the belt is ever pulled it could naturally break. If you ever see this sound, the best thing is to change the belt and the problem will be solved almost without fail.

A sharp squeal on the Volvo 340:

This remains the most common concern, but also the least dramatic. It usually comes from cold, but could recur when you drive sometimes. However, it stops instantly. This inconvenience usually comes when the accessory belt is slack. It will suffice tender and it's done. Small warning, if it remains in this state for too long, the belt could deteriorate and cause a more serious problem in the long term.

It is the opposite of the previous concern. The belt is certainly too tight or even too small. You can imagine what you should do!

Alternator noise on a Volvo 340

In the event that it is indeed the alternator which produces this sound and not your belt, then the concerns will be found to be really different. However, the sound emitted could have resemblances compared to that of a strap, that is to say a high hiss. The problem could arise from a electrical failure, this remains rather usual. If it happens that the voltage useful for the good activity of this Volvo 340 is insufficient, it usually refers to the lack of power of the indicator lights or bulbs inside your automobile. Assuming that the power gap is excessive, it happens that the battery indicator can be in operation. If you want to make a voucher diagnostic of this problem, it is still possible to use a voltmeter and check the tension via the + and - of your battery, the engine runs naturally. If ever the voltage is lower than that recommended by the battery, the problem could therefore come from the alternator. In this case, you usually need to change it.

Conclusion:

A new alternator sound usually comes from the alternator belt, but could also come from the alternator itself. financially, the alternator belt is relatively cheaper than the alternator. Have a costing done at a auto repairer rather than embarking on work, since we are not necessarily sure of the source of the problem.
