You can imagine it, but the alternator is a key element in an engine. It is himself who is responsible for transforming energy of the engine block of this volvo 240 in Electricity supply in order to recharge the battery. If there is a malfunction, this could essentially cause electrical failures. It therefore seems essential to deal with it. However, the concern could also arise from his belt, sometimes pulleys. We will see in this text where the problems related to noise that comes out.noise-alternator-volvo-240

Alternator belt noise on a Volvo 240

La alternator belt, also known as an accessory belt, is the essential component that contributes to the proper functioning of the alternator. It is the latter which, thanks to its rotation, carries the alternator and will provide the means to produce electricity. However, it also serves to rotate different pumps of the engine block. If it ever breaks, it can make damages frankly important in your engine of this volvo 240.

A metallic noise on the Volvo 240:

Here is a hazard that often comes Cold. The most common cause is that some of the streaks on this belt turn out to be damaged. However, this could also happen if the pulley is slightly out of the gon. In case the belt deteriorates it can naturally break. If you ever recognize this noise, the ideal thing is to replace the belt and the problem will be almost completely erased.

A sharp squeal on the Volvo 240:

Indeed, it is the most recurring hassle, but also the least critical. It often comes from cold, but will sometimes even come back hot from time to time. However, it suddenly disappears. This noise usually comes as soon as the accessory belt is relaxed. It is necessary to tender and it's over. Be careful, when it stays in this state for too long, the belt can be damaged and cause a more serious incident at the end. This sharp screeching also occurs at times in the event that the damper pulley happens to be damaged, but it's rarer.

A slight hiss or breath on the Volvo 240:

It is the opposite of the previous hassle. Your belt is probably too tight or too small. You can imagine what you have to do!

Alternator noise on a Volvo 240

Assumed that it is indeed the alternator which creates this noise and not your belt, in this situation the problems will be fundamentally singular. However, the noise you hear may have similarities compared to that of a strap, so a high hiss. The concern will sometimes arise from a electrical failure, it's pretty ordinary. If it happens that the voltage essential for the good activity of your volvo 240 is usually weak, this is generally apparent from the lack of alertness of the indicator lights or bulbs inside the car. In case the alertness is excessive, it is possible that the battery indicator stays in operation. So as to make a real diagnostic worry, it is entirely feasible to use a voltmeter to check the tension on the + and minus of the battery, the ignition on obviously. If the voltage is lower than that suggested on the battery, the problem could therefore come from the alternator. So, it will generally have to be replaced.

Conclusion:

Alternator noise often comes from the alternator belt, but will sometimes also come from the alternator itself. Economically, an alternator belt is relatively cheaper compared to the alternator. Ask the price at a auto repairer before starting repairs, as you are not necessarily sure of the source of the problem. We hope this guide helped you, if so don't hesitate to post a comment. See you soon with your volvo 240.
