It is never pleasant to find out a noise from your car you don’t know where from. So what if you locate a serpentine belt noise that stays on your Renault Koleos? It is very plausible that this is a minor issue, but before being sure, it is better to execute some investigations. If this belt noise comes from your serpentine or driving belt, our team has written a post to support you locating and correcting it. First, we will look at the serpentine belt noises on your Renault Koleos and then we will take a look at the sources of these sounds.serpentine-belt-noise-renault-koleos

I experience noises from serpentine belt Renault Koleos

The best technique to check the state of your belts is to listen to your vehicle. As soon as you recognise sounds such as squealing or bells, you should take a closer look to examine their origin. The role of the serpentine belt or driving belt of your Renault Koleos 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 critical in the normal use of your vehicle. The serpentine belt is said to be asynchronous, i.e. unlike the timing belt, it has the capacity to drive distinctive engine components at variable speeds.

I find out squealing noises on my serpentine belt Renault Koleos

This type of squealing belt noises on Renault Koleos, which will often be acute, can mostly appear when the engine is cold, or when the acceleration increases in intensity. . This type of noise must be heavy and it is often quite simple to associate it with one of these belts. To examine, 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 complicated for you to point a belt noise on your Renault Koleos. The reason of this issue can be linked to the damper pulley, which works 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 the opportunity that this phenomenon is annodine. As the serpentine belt of your Renault Koleos is exposed, it may squeak due to excessive humidity due to weather conditions and it may stop with a change in conditions. Keep in mind to examine the state of your belt (crack, crack), if this is the case swap it, otherwise simply tighten the belt.

I find out loud serpentine or driving belt noises Renault Koleos

Just like squealing, a driving belt noise on your Renault Koleos that sounds like a loud grinding sound can reveal a lot about its state. It is therefore imperative that you look further and find the reason for this sound that can indicate 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 issue. Make sure to examine first the serpentine/driving belt which in most cases is the reason of this issue, otherwise it will be necessary to swap the tensioner or pulley.

I find out bearing noises on the serpentine belt of my Renault Koleos

Finally, if in your case you discern a bearing belt noise on Renault Koleos, 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 prescribed 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 replace it if it is too short. If after checking all thoses possibilities, you still identify a belt noises, read our article about timing belt noises on Renault Koleos which could maybe help you.
