It is never pleasurable to listen to a noise from your car you don’t know where from. So what if you notice a serpentine belt noise that stays on your Renault Megane? It is very plausible that this is a unimportant issue, but before being sure, it is better to carry out some checks. If this belt noise comes from your serpentine or driving belt, our team has written a post to help you finding and correcting it. First, we will look at the serpentine belt noises on your Renault Megane and then we will take a look at the sources of these sounds.
I encounter noises from serpentine belt Renault Megane
The best way to control the state of your belts is to listen to your vehicle. As soon as you detect sounds such as squealing or bells, you should take a closer look to check their source. The function of the serpentine belt or driving belt of your Renault Megane is to transmit the movement of the engine to the secondary parts that it will supply with energy. Like steering, air conditioning, water pump. Its role is therefore essential in the normal overall performance of your vehicle. The serpentine belt is said to be asynchronous, i.e. unlike the timing belt, it has the ability to drive different engine parts at variable speeds.
I listen to squealing noises on my serpentine belt Renault Megane
This sort of squealing belt noises on Renault Megane, which will often be acute, can mostly happen when the engine is cold, or when the acceleration increases in intensity. . This sort of sound must be heavy and it is normally quite simple to relate it with one of these belts. To check, do not hesitate to open your bonnet, engine running cold and check the source of this noise, the serpentine or driving belt being accessible, it should not be too difficult for you to point a belt noise on your Renault Megane. The reason of this issue can be linked to the damper pulley, which acts as a damper to get rid of 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 the possibility that this phenomenon is annodine. As the serpentine belt of your Renault Megane is exposed, it may squeak due to excessive humidity due to weather conditions and it may stop with a change in conditions. Remember to check the state of your belt (crack, crack), if this is the case change it, otherwise simply tighten the belt.
I listen to loud serpentine or driving belt noises Renault Megane
Just like squealing, a driving belt noise on your Renault Megane that sounds like a loud grinding sound can tell you a lot about its state. It is therefore necessary that you look further and locate the cause 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 alternatives, the dynamic belt tensioner or the disengageable pulley of the alternator may be at the source of this issue. Don’t forget to check first the serpentine/driving belt which in most cases is the reason of this issue, otherwise it will be necessary to change the tensioner or pulley.
I listen to bearing noises on the serpentine belt of my Renault Megane
Finally, if in your case you identify a bearing belt noise on Renault Megane, 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 suggested and cause the entire system to overvoltage, resulting in this whistling noise or slight rolling noise. The risk 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 swap it if it is too short. If after checking all thoses alternatives, you still identify a belt noises, read our article about timing belt noises on Renault Megane which could maybe help you.
