When does my Nissan Pulsar produce a loud noise?
One way to discover a noise from your Nissan Pulsar is to establish when it occurs. Indeed, some problems can be connected to components that are only stressed under certain occasions. It is this technique that we will focus on in this first part.
Loud noise Nissan Pulsar when accelerating
Loud noise on Nissan Pulsar that takes place when you are accelerating can be symptomatic of multiple failures. In fact, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will cause a much higher noise than during normal operation. In addition, it is also highly plausible that loud noise on your Nissan Pulsar is linked to a wheel bearing, which is one of the most common origins of these types of signs of illness. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the issue may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Nissan Pulsar is stopped
If your Nissan Pulsar makes a loud noise while not accelerating, engine on, the issue may be connected to poor air intake. An air intake hose that has come loose or has a hole in it may be the cause.
Where does loud noise come from on my Nissan Pulsar and how can I be sure of its origin?
Now that we have determined the origin of the sound, we will look into the verification stage to ensure that this is the concern you are encountering.

The loud noise comes from the wheels of my Nissan Pulsar
As we have seen previously, loud noise from the wheels of your Nissan Pulsar may be connected to two main complications. 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 keep 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 swap it or them quickly. If it is a deformed tire, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Nissan Pulsar that is the issue, you will tend to feel a vibration in the direction of the automobile as you go faster. In both situations, you will have to go to your mechanic to replace the tires or do a balancing.

The loud noise comes from the engine of my Nissan Pulsar
In case you have recognized loud noise as coming from the engine of your Nissan Pulsar, 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 experience a power loss during your acceleration. If the loud noise on your Nissan Pulsar is related to air intake, the control 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 generate 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 automobile to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have discovered comes from the exhaust pipe of your Nissan Pulsar, 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 Nissan Pulsar, 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.
