Car Noises and What They Mean

An automobile is a highly complex collection of various parts and components, and knowing different car noises and what they mean is very important for fixing a multitude of car problems that frequently plague these machines. You may have realized by now that your car makes noises that vary in loudness, duration and nature. Elemental understanding of these different noises will help you in instantly deciphering the faulty part, and this will make the task of auto repair a much simpler one.

Knowledge of car noises and what they mean does not imply that you need to be an auto mechanic who knows all about cars and their car parts. It simply means that you have basic knowledge about your vehicle, and this makes troubleshooting of the vehicle easier. Auto mechanics often sneer at car owners who cannot recognize the noises that their car makes. To avoid such embarrassing situations, and also to avoid car crashes, you can learn a little about common car noises and what they mean.

Different Car Noises and What They Mean

Knocking Noise
These are the most common noises you may hear while driving. Investigate its cause immediately, or you may end up spending a considerable amount of money repairing the source of the problem later on. The potential damage could be to your wheel bearings (if the noise occurs while turning), your driveshaft center bearing, loose bolts in the torque converter, or a faulty connecting rod. Learn to differentiate between the many weird car noises and you will soon figure out what each noise specifically means.

Squealing Noise
This noise originates from the tires or it implies some fault in the braking mechanism. Low air in tires, faulty alignment of the wheels, faulty air conditioning compressor belt, or worn out brake components could be the cause of this noise. Knowing these car noises and what they mean will enable you to fix problems with the braking system rapidly, thus reducing the possibility of disaster.

Rattling Noise
This is one noise that you will hear very often in an automobile, so be alert whenever you hear it. Any loose nuts or bolts could be the culprit of these noises, and it's important that you get to the bottom of it as soon as possible. It could imply a fault in the exhaust system of the car, or even loose brake pads. Get it looked at immediately.

Backfiring Noise
This noise most commonly surfaces when you are starting the car, or when you suddenly accelerate more. The cause of this noise lies in the ignition chamber, and you need to check for faulty ignition timing, leaking valves, or a defective ignition system. Diagnosing car noises and what they mean requires a keen ear, and some elemental knowledge of the many parts that constitute an automobile.

Clicking Noise
This noise will almost always occur in a rhythm, and surface at regular intervals. The many causes of this noise are defective wheel bearing, low engine oil level, possibly a loose hubcap, or a bent fan blade. Learn the art of troubleshooting car noises and you will reap the benefits of this knowledge. Many people spend unnecessary amounts of money on car repair when they can easily fix the cause of the problem by themselves.

Popping Noise
This is a very loud and distinct noise and usually implies that something big and expensive has broken down. So brace yourself, as it could mean a leaking valve, incorrect engine timing, rotor problems, or wire problems. These don't sound very serious but if you ignore this noise it will come back to haunt you at some point in the future.

Hissing Noise
This type of noise definitely implies a leak somewhere under the hood of the car. The cooling system of the car is the most likely place that this hiss is emanating from. Use a torchlight and find the source of the noise. Common car noises are aplenty, but there are only so many things that make a particular sound. This further highlights the importance of knowing weird car noises and what they mean.

Over a period of time, you will learn to differentiate between the various noises. Every car makes noises once in a while, but you as the driver must know which noises should be ignored and which noises should be immediately looked into. Regularly consult an auto mechanic about diagnosing car noises and what they mean, and pretty soon you will become an expert yourself.
