It may not be unknown to you, nevertheless the alternator is an essential component within an engine. It is he who is responsible for transforming energy of the engine block of this Volvo 265 in Electricity supply in order to recharge the battery. If there is a malfunction, it could mainly cause electrical failure. It is in fact essential to take care of it. However, the malfunction could also come from the belt, and even pulleys. We will see in this text where the problems according to the noise that you hear.noise-alternator Volvo-265

Noise alternator belt on a Volvo 265

La alternator belt, also known as the accessory belt, is the most important component that contributes to the proper functioning of the alternator. It is he who via his convolution carries the alternator and makes it possible to manufacture electricity. But it is also used to make different pumps of the engine block. In case it breaks, it can make damages really important in the engine of the Volvo 265.

A metallic noise on the Volvo 265:

It is a hazard that generally comes Cold. The most common reason is that the ridges in the belt have deteriorated. But it could also happen if the pulley is very slightly off-axis. If the belt falls apart it can of course break. If you ever see this noise, the best thing to do is to change the belt and the malfunction will be erased almost every time.

A sharp squeal on the Volvo 265:

This is the most common problem, but also the least important. It often comes cold, but will sometimes reappear when you are driving sometimes. Nevertheless, he suddenly stops. This inconvenience usually comes when the accessory belt is not tight enough. It will suffice to tighten and it's over. Be careful, if it remains in this situation for too long, the belt may be damaged and eventually cause a more dramatic incident. This sharp noise also appears at times in the event that the damper pulley happens to be deteriorated, however it is rarer.

A slight hiss or breath on the Volvo 265:

This is the opposite of the previous problem. The belt is probably too tight or even too short. You can imagine what to do!

Alternator noise on a Volvo 265

Assuming it's the alternator making the noise and not the belt, then the concerns are going to be really different. However, the noise we hear may have similarities compared to that of a belt, so a high hiss. The concern will sometimes come from a electrical failure, this remains rather usual. If ever voltage essential for the good operation of your Volvo 265 is usually deficient, this is generally seen when the power of the warning lights or bulbs inside your automobile is insufficient. If the insufficient power is unusual, it may be that the battery indicator either in operation. So as to achieve a real diagnostic of this concern, it remains useful to use a voltmeter and take the tension via the + and - of its battery, with the engine running of course. Assuming that the voltage is lower than that recommended by the battery, the malfunction can therefore come from the alternator. In this case, it will generally have to be changed.

Conclusion:

A new alternator noise generally comes from the alternator belt, but will sometimes also come from the alternator itself. Economically, the alternator belt is relatively cheaper compared to the alternator. Get the price from a mechanic rather than attempting repairs, quite simply because there is no guarantee of the cause of the malfunction. Hope this text has helped you, if so you can post a comment. See you soon with your Volvo 265.
