Bad Engine Noises: Raleigh, NC


Engines have their own distinct sound, whether they hum gently or roar triumphantly. Eventually, you’ll become accustomed to that sound, so hearing a new one can be unsettling. It is important to pay attention to sounds such as squealing, grinding, and others.

But, what can bad noises from your engine mean in Raleigh, NC?

In this article, we’ll explore some common engine sounds and their meanings. Despite not being comprehensive, this information can help you understand some of the most common causes of odd noises in your car’s engine. Let’s get into it!

What The Top 5 Bad Noises From Your Engine Mean in Raleigh, NC

1.    Squealing

Screaming and shrieking from people aren’t usually good signs, and the same goes for cars. Under the hood, a squeal may be caused by a loose or worn serpentine belt. In addition to controlling engine accessories, this belt also controls the alternator and water pump.


Squealing can also be caused by other factors if it occurs at other times. You should replace your brake pads if your car squeals when you step on the brake pedal or during turns.

2.    Whistling

There may be an issue with your vehicle’s weather-stripping if you only hear this noise inside your car while driving. If you only hear this noise inside your car while driving, there may be an issue with your vehicle’s weather-stripping.


Despite their importance, hoses are the weakest parts of your engine’s cooling system. Your car’s engine’s constant circulation of air and cooling fluid can crack hoses, resulting in their vacuum seal being broken. Through these holes, air may be escaping, causing the whistling sound.


After turning off your car, you may still hear whistling from the radiator pressure cap. In some cases, the rubber gasket on this cap breaks, which allows air to leak through and release excess heat from the overheated coolant.


3.    Clicking or Tapping

A sound that sounds like tapping, ticking, or clicking may indicate that your car is low on oil. You can verify this by checking the oil. Adding more oil can solve the problem in the short term if the levels are too low.


It is however only a short-term fix, and should only be used to prevent damage to your engine while you drive to the service center. To locate the root cause of low oil levels, an inspection is necessary.


A valvetrain problem could cause the tapping noise if the oil levels aren’t low. A serious situation like this should also be addressed immediately.

4.    Knocking

You’re likely hearing a detonation knock when you’re driving if you hear a metallic knock or ping. Several cylinders in your engine are detonating simultaneously due to a mixture of fuel and air. In addition to using the wrong octane gas in your engine, this could also be caused by poor timing, a lean air/fuel mix, or a damaged knock sensor.


Knocking can also be caused by other factors, and they should all be addressed as soon as possible.

5.    Grinding

Your car can make a grinding noise for a variety of reasons. It’s possible that worn-out bearings are to blame if you hear this grinding noise while driving and idling. When you shift, the grinding noise is likely caused by a worn clutch. Having a grinding sound when turning a corner could be a sign you need to replace your CV joint or another suspension issue.


Brake pads could be worn down to the metal if you hear grinding noises when you brake. You should have your car inspected as soon as possible if any of these sounds occur.
