When does my Chevrolet Spark make a loud noise?
One way to detect a noise from your Chevrolet Spark is to identify when it occurs. Indeed, some complications can be related to components that are only stressed under certain occasions. It is this method that we will focus on in this first part.
Loud noise Chevrolet Spark when accelerating
Loud noise on Chevrolet Spark that starts when you are accelerating can be symptomatic of several failures. In fact, if you experience a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will generate a much higher noise than during normal use. Moreover, it is also highly plausible that loud noise on your Chevrolet Spark is associated with a wheel bearing, which is one of the most common causes of these types of symptoms. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

The loud noise comes from the wheels of my Chevrolet Spark
As we have seen earlier in this article, loud noise from the wheels of your Chevrolet Spark may be related to two main disorders. If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So bear in mind to examine by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case replace it or them right away. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Chevrolet Spark that is the matter, you will tend to feel a vibration in the direction of the car as you go faster. In both situations, you will have to go to your mechanic to change the tires or do a balancing.

The loud noise comes from the engine of my Chevrolet Spark
In case you have discovered loud noise as coming from the engine of your Chevrolet Spark, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected with a compression loss during the engine ramp-up phase, so you should encounter a power loss during your acceleration. If the loud noise on your Chevrolet Spark is related to air intake, the check will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would induce an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then examine that the engine idle speed is not random. In case you confirm one of these two trouble, take your car to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have detected comes from the exhaust pipe of your Chevrolet Spark, it is highly plausible that you have rust if your vehicle is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Chevrolet Spark, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To validate this, get help from someone who will stand under the vehicle while you accelerate to find the exact area of origin of this noise. If it is a hole, you can repair it with a putty provided for this purpose, or, if it is a collar, “reattach” it. If it is cut or the hole is too big, it is better to get closer to your mechanic.
