Being subject to constant noise on your vehicle tends to be annoying, a vehicle is so sophisticated that it is generally difficult to locate its origin and even more so to find the part that produces it. If you have already experienced a clicking noise on your Alfa Romeo 147, we will probably be able to help you. Indeed, our editorial staff decided to write this content page in order to review the main causes of a clicking noise on Alfa Romeo 147. 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 sources of clicking noise on Alfa Romeo 147 coming from your suspensions.
I find out a clicking noise on Alfa Romeo 147 located on my engine
Check your high engine
If you find out a clicking noise on Alfa Romeo 147, and this sound is based at the top of the engine, it means that it comes from your cylinder head and its associated parts. Two elements can be the causes of these ticking noises on Alfa Romeo 147. 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 vanish when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this case, remember to change them.
Check your low engine
If you have determined the area of source of the Alfa Romeo 147 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both cases, 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 replace the engine of your Alfa Romeo 147.
Combustion problem
Finally, if you have the feeling that this clicking noise on Alfa Romeo 147 is linked to the combustion of your engine, there are three possible triggers of it. Check the condition 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 cause, comes from your injection, which is either blocked or one or more injectors are injured. In this circumstance, do not hesitate to read this content page which deals in detail with the different injection sounds on Alfa Romeo 147.

Check the condition of the gimbals
One of the most basic triggers of a clicking noises in the direction of your Alfa Romeo 147 is linked with the direction of the vehicle. 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 create 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 rapidly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it.

Check the rest of your direction
Finally, when you recognise a clicking noise on your Alfa Romeo 147, 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 circumstance, 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 find out a clicking noise on Alfa Romeo 147 coming from my suspensions
Check the suspension
If you experience a clicking noise on your Alfa Romeo 147 each time you pass a speed bump, it is highly plausible that your suspension block is the induce 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 verify if this is the trouble that concerns you, take a dented road and, at low speed, listen to the sound coming from your front axle when you pass over holes. If these are the cups, consider changing them quickly as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Alfa Romeo 147 at the suspension level, it is widely plausible that spring wear or shock cylinder deformation may be a cause. To verify the shape of the spring, position the car 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 significant it suggests that that most likely your springs are worn, if you see 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 think about changing it or them. If you have the feeling that this noise is more like a squeaking noise on Alfa Romeo 147 than a clicking noise, don’t hesitate to consult this article.
