It is never enjoyable to notice a noise from your car you don’t know where from. So what if you detect a serpentine belt noise that persists on your Mercedes Classe M? It is extremely plausible that this is a unimportant trouble, but before being sure, it is better to conduct some inspections. If this belt noise comes from your serpentine or driving belt, our team has written a post to help you locating and solving it. First, we will look at the serpentine belt noises on your Mercedes Classe M and then we will check out the sources of these noises.
I experience noises from serpentine belt Mercedes Classe M
The best way to check the condition of your belts is to listen to your car. Immediately after you recognize noises such as squealing or bells, you should take a closer look to check their origin. The role of the serpentine belt or driving belt of your Mercedes Classe M is to transmit the movement of the engine to the secondary components that it will supply with energy. Like steering, air conditioning, water pump. Its role is therefore fundamental in the normal operation of your car. The serpentine belt is said to be asynchronous, i.e. unlike the timing belt, it has the ability to drive different engine components at variable speeds.
I notice squealing noises on my serpentine belt Mercedes Classe M
This type of squealing belt noises on Mercedes Classe M, which will often be acute, can generally occur when the engine is cold, or when the acceleration increases in intensity. . This type of noise must be heavy and it is obviously quite simple to associate it with one of these belts. To check, do not hesitate to open your bonnet, engine running cold and check the origin of this noise, the serpentine or driving belt being apparent, it should not be too difficult for you to point a belt noise on your Mercedes Classe M. The cause of this trouble can be linked to the damper pulley, which acts as a damper to reduce irregularities in the tension in the motor cycle and therefore in the energy transmission to the belt. This results in a loose belt that will jerk. However, you still have a chance that this phenomenon is annodine. As the serpentine belt of your Mercedes Classe M is exposed, it may squeak due to excessive humidity due to weather conditions and it may end with a change in conditions. Keep in mind to check the condition of your belt (crack, crack), if this is the case change it, otherwise simply tighten the belt.
I notice loud serpentine or driving belt noises Mercedes Classe M
Just like squealing, a driving belt noise on your Mercedes Classe M that sounds like a loud grinding sound can tell you a lot about its condition. It is therefore necessary that you look further and locate the reason for this sound that can signal the end of your belt’s life. Like squealing noise, it can be identified in most cases when cold . It generally means a worn pulley whose streaks no longer allow it to be driven properly. Other possibilities, the dynamic belt tensioner or the disengageable pulley of the alternator may be at the origin of this trouble. Don’t forget to check first the serpentine/driving belt which in most cases is the cause of this trouble, otherwise it will be necessary to change the tensioner or pulley.
I notice bearing noises on the serpentine belt of my Mercedes Classe M
Finally, if in your case you identify a bearing belt noise on Mercedes Classe M, it is plausible that it is linked to a serpentine belt that is too tight . Indeed, it is plausible that its size may be smaller than recommended and cause the entire system to overvoltage, resulting in this whistling noise or slight rolling noise. The problem in this case is that the bearing bearings or the Damper pulley may fail . Remember, therefore, to stretch the belt to limit the risks or to replace it if it is too short. If after checking all thoses possibilities, you still notice a belt noises, read our article about timing belt noises on Mercedes Classe M which could maybe help you.
