Being subject to repeated noise on your car tends to be frustrating, a car is so sophisticated that it is constantly difficult to locate its origin and even more so to find the part that generates it. If you have already experienced a clicking noise on your Renault Espace 4, we will almost certainly be able to support you. Indeed, our editorial staff decided to write this document in order to review the main causes of a clicking noise on Renault Espace 4. This is why, firstly, we will see 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 sources of clicking noise on Renault Espace 4 coming from your suspensions.
I perceive a clicking noise on Renault Espace 4 located on my engine
Check your high engine
If you perceive a clicking noise on Renault Espace 4, and this sound is based at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two parts can be the causes of these ticking noises on Renault Espace 4. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will hear these clicking noises, generally when cold and vanish 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.
Check your low engine
If you have identified the area of origin of the Renault Espace 4 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both situations, the risk in the long term is the breakage of the motor. These two maintenance are very complex and most mechanics will suggest you to swap the engine of your Renault Espace 4.
Combustion problem
Finally, if you have the feeling that this clicking noise on Renault Espace 4 is connected to the combustion of your engine, there are three possible triggers of it. Check 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 components to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors are damaged. In this case, do not hesitate to consult this document which deals in detail with the different injection sounds on Renault Espace 4.
I perceive a clicking noise on Renault Espace 4 in my direction
Check the state of the gimbals
One of the most basic causes of a clicking noises in the direction of your Renault Espace 4 is linked to the direction of the car. 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 damage the cardan shaft very quickly and must be replaced very quickly, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it.

Check the rest of your direction
Finally, when you know a clicking noise on your Renault Espace 4, 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.

Check the suspension
If you encounter a clicking noise on your Renault Espace 4 when you pass a speed bump, it is really possible that your suspension block is the reason of the sound. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its task and during small jolts that compress the suspensions. To examine if this is the issue that worries you, take a dented road and, at low speed, pay attention to the sound originating 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 Espace 4 at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a reason. To examine the shape of the spring, place 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 examine 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, make sure 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 think about replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Renault Espace 4 than a clicking noise, don’t hesitate to consult this article.
