Being subject to frequent noise on your automobile tends to be annoying, a automobile is so elaborate that it is usually difficult to determine its origin and even more so to find the part that generates it. If you have already experienced a clicking noise on your Renault Koleos, we will most likely be able to support you. In fact, our editorial staff decided to compose this content page in order to review the main causes of a clicking noise on Renault Koleos. This is why, firstly, we will look at what are the causes of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the origins of clicking noise on Renault Koleos coming from your suspensions.
I perceive a clicking noise on Renault Koleos from my engine
Examine your high engine
If you perceive a clicking noise on Renault Koleos, and this noise is based at the top of the engine, it means that it comes from your cylinder head and its associated parts. Two parts can be the triggers of these ticking noises on Renault Koleos. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, often when cold and disappear when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this case, remember to change them.
Examine your low engine
If you have founded the zone of source of the Renault Koleos clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both cases, the risk in the long term is the breakage of the motor. These two maintenance are very complicated and most mechanics will advise you to replace the engine of your Renault Koleos.
Combustion problem
Finally, if you have the feeling that this clicking noise on Renault Koleos is linked to the combustion of your engine, there are three possible causes of it. Examine the state of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is possible that your timing belt is shifted and that it does not properly manage the timing of the various engine elements to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors are destroyed. In this case, do not hesitate to check this content page which deals in detail with the different injection sounds on Renault Koleos.
I perceive a clicking noise on Renault Koleos in my direction
Examine the state of the gimbals
One of the most basic triggers of a clicking noises in the direction of your Renault Koleos is connected to the direction of the automobile. Indeed, the cardans and their bellows are parts that are constantly stressed during your changes of direction or that you turn your wheels and a wear of one of them can make a ticking type of sound when you approach the stop zone of your steering. A bellows with holes will harm the cardan shaft very quickly and must be swapped very quickly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it.

Examine the rest of your direction
Finally, when you know a clicking noise on your Renault Koleos, it is possible that it is the direction that is involved. Just like the gimbals, the steering part is mobilized when you turn your wheels. If this is the case, the parts that may have been damaged due to normal wear and tear or impact (e. g. sidewalks) are steering rods, stabilizer bar silentblocks or steering triangles.
I perceive a clicking noise on Renault Koleos coming from my suspensions
Examine the suspension
If you experience a clicking noise on your Renault Koleos once you pass a speed bump, it is extremely possible that your suspension block is the cause of the noise. In fact, it may be the suspension cups, which, when they are dead, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role and during small jolts that compress the suspensions. To check if this is the trouble that worries you, take a dented road and, at low speed, pay attention to the noise coming from your front axle when ever you pass over holes. If these are the cups, consider changing them soon as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Renault Koleos at the suspension level, it is highly possible that spring wear or shock cylinder deformation may be a cause. To check the condition of the spring, position the vehicle on a flat surface and measure that the heights from the ground to the bottom of the body are similar on each side (empty car for measurement). You can also check between the front and rear, if there is a gap too large it means that most likely your springs are worn, if you observe a leak go a little further in the article to have the answer to this problem. For the cylinder the verification is visual, ensure that it seems to work in a straight axis. And that there is no angle that would alter its proper functioning. If one of them breaks in both situations, you should consider replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Renault Koleos than a clicking noise, don’t hesitate to consult this article.
