Being subject to regular noise on your car tends to be frustrating, a car is so elaborate 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 Opel Zafira, we will most likely be able to support you. Indeed, our editorial staff decided to write this article in order to review the main causes of a clicking noise on Opel Zafira. This is why, firstly, we will check out what are the origins 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 Opel Zafira coming from your suspensions.
I discover a clicking noise on Opel Zafira located on my engine
Examine your high engine
If you discover a clicking noise on Opel Zafira, and this noise is located at the top of the engine, it means that it originates from your cylinder head and its accompanying parts. Two elements can be the triggers of these ticking noises on Opel Zafira. 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, generally when cold and go away when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this circumstance, remember to change them.
Examine your low engine
If you have determined the zone of origin of the Opel Zafira clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both circumstances, the risk in the long term is the breakage of the motor. These two fixes are very complex and most mechanics will suggest you to change the engine of your Opel Zafira.
Combustion problem
Finally, if you have the feeling that this clicking noise on Opel Zafira is connected to the combustion of your engine, there are three possible triggers of it. Examine the state of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is plausible that your timing belt is shifted and that it does not properly manage the timing of the various engine parts to promote good combustion. And finally, the most classic trigger, comes from your injection, which is either blocked or one or more injectors are destroyed. In this case, do not hesitate to read this article which deals in detail with the different injection sounds on Opel Zafira.
I discover a clicking noise on Opel Zafira in my direction
Examine the state of the gimbals
One of the most regular reasons of a clicking noises in the direction of your Opel Zafira 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 changed in a short time, otherwise the entire cardan shaft will have to be changed. Consider taking a look at it. If you would like more detailed information about gimbals noises on Opel Zafira, do not hesitate to read this complete guide.
Examine the rest of your direction
Finally, when you experience a clicking noise on your Opel Zafira, it is plausible 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 discover a clicking noise on Opel Zafira coming from my suspensions
Examine the suspension
If you experience a clicking noise on your Opel Zafira when you pass a speed bump, it is extremely plausible that your suspension block is the reason of the noise. Indeed, 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 verify if this is the problem that concerns you, take a dented road and, at low speed, pay attention to the noise originating from your front axle when ever you pass over holes. If these are the cups, consider changing them promptly as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Opel Zafira at the suspension level, it is widely plausible that spring wear or shock cylinder deformation may be a cause. To verify the condition 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 identical on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too large it means that most likely your springs are worn, if you discover a leak go a little further in the article to have the solution 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 changing it or them. If you have the feeling that this noise is more like a squeaking noise on Opel Zafira than a clicking noise, don’t hesitate to consult this article.
