10 Noises Your Car Makes
Why You May Need To Stop By The Shop
Modern vehicles are very reliable, yet they still require regular maintenance. Often, many drivers disregard the necessary repairs until they hear or notice a different noise emitting from the car.
Are familiar with how your vehicle sounds? Any unusual or new sounds should alert you to contact a reliable auto repair shop. Here is our list of 10 noises your car makes.
Remember, most of the cars manufactured today are very silent. A vehicle that fires on all cylinders and working well, so to speak, hardly makes a whisper. Understandably, it can be irritating and confusing to hear some unusual racket emitting from your car whether from the rear or under the hood.
It is important to know the sounds of your vehicle it’s trying to informing you about something crucial. Once you hear any unfamiliar or unexpected sound, it may be time to bring your car one of our reliable mechanic’s at Canadian Super Shop. To help you to decipher those noises, here’s a list of sounds that cars make and what they mean.
1. Sound Of Screeching Brakes
The screeching sound you hear when stopping or pressing your foot on the brake pedal is a clear signal that the brake pads of your car are worn out.
At times, brakes screech a little when the vehicle’s tires are wet. Often, this goes away once the water disappears. It causes car noises when stopping or turning. Nonetheless, if the screeching continues, it shows that your vehicle’s brake pads are worn out and needs replacement.
If you hear a grinding sound accompanying the screeching, it’s the noise of the metal scraping against another metal. That means the brake calipers are also affected and therefore, you should repair or replace them.
2. A Knocking in the Engine
Most people panic when they hear this irritating sound. Using a wrong type of gasoline will cause the knocking in the car engine. Eventually, it causes car noises when driving.
Fueling your vehicle with a low-grade gasoline when it requires high-quality octane may cause damage to the spark plugs. As a result, the engine pistons will move erratically; you may hear a knocking sound. Consult the car owner’s manual to ensure that you’re using the right type of gasoline.
3. Rattling Under the Car
Sometimes it can be difficult to identify the sounds emitting from under your vehicle. But, you can’t mistake a continuous rattling sound from underneath the driver’s seat. If you hear this sound, it should notify you that there’s something loose on the car, could be the exhaust.
Fortunately, it’s very easy to spot what’s causing the noise under the vehicle. Often, the item hangs down in plain sight. You possibly could tighten up a loose exhaust with a screwdriver.
4. Clicking Sound Under The Hood
You shouldn’t panic when you hear a soft, clicking sound under the hood of your vehicle. Could it be low oil level in the engine? Ensure you check the oil the next time you stop. Topping up the oil could halt the clicking sound. You shouldn’t hear any strange noises when driving.
Lack of pressure at one point of the transmission system could also be a cause for concern. Again it maybe another clicking sound. In some instances, the noise will be heard if there’s a blockage in the system which is preventing the engine oil from circulating appropriately.
If the engine has the right amount of oil, the clicking sound is most likely a result of a faulty valve train that needs to be adjusted.
5. Popping Sound in the Engine
There are several causes of a popping sound in the car engine. Defective spark plugs mainly cause it. If this sound is followed by the car jerking or engine hesitation, then the spark plugs are either dirty or worn.
The most severe issue could be damaged ignition of the car. But first, check if the spark plugs are faulty. Luckily, they are cheap, and you can do the replacement yourself without the seeking the service of a mechanic.
Just visit your local automotive store and buy the required number of spark plugs. In case, the popping sound persists, take your car to a reliable auto shop.
6. A Roaring Sound
Do you hear a roaring sound when you put your foot on the gas pedal? Does it emulate a plane taking off? If yes, then there could be a problem with the exhaust system of the car that could be making the engine work extra hard.
Also, there could be some problems with the transmission. Hope and pray that this isn’t the case since it is expensive to fix transmission problems.
Vehicles with automatic systems, the noise, could be a result of improper switching of gears. The sync settings could be slipping. Whether it’s the transmission or the exhaust, it’ll cost you some money and time to diagnose the problem and repair it.
7. Hissing Underneath the Hood
The hissing sound you hear when you first pull into the driveway and shut off your vehicle doesn’t mean there’s a snake nearby. It shows that something is leaking in your car engine, and hissing as the liquid falls on the hot engine parts.
The leaking substances could be the engine oil, transmission fluid or coolant. On the other hand, the hissing sound could mean your engine is overheating. Once you hear a hissing sound under the hood, get out of your vehicle and check if there is a problem.
Perhaps, you’ll see a red, black or fluorescent green liquid pooling on the garage floor or the driveway. Your mechanic should fix this as quickly as possible.
8. A Flapping Noise
Do you hear a flapping sound similar to a flat tire, but all the tires are inflated? If yes, it’s most likely that you have a broken fan belt. You should replace it.
The replacement of fan belt is standard and quite easy fix. It’s also relatively cheap. But, if you disregard the flapping sound and continue to drive for an extended period, it could cause more severe problems and costly repairs. Pay attention to the flapping sound and act very quickly to get the fan belt fixed.
You may hear a loud bang when you start your vehicle (similar to the sound of a cherry bomb exploding or a shotgun blast). It’s known as a backfire and often accompanied by a thick cloud of black smoke that comes from the tailpipe.
It means there is a serious problem with the catalytic converter. This converter ensures that the emissions coming from the tailpipe of your car are non-pollutants.
Unfortunately, it is very expensive to replace it. Remember, your vehicle won’t operate or start at all if the catalytic converter shuts down entirely.
10. Whirring Sound Under the Car
Noises from under the vehicle are confusing. Therefore, identifying the real cause of the sound can be very challenging. But, if you hear a whirring sound underneath your car, and you find that the car is pulling to one side when driving, could it be a wheel?
Other possible causes of a whirring sound include the need for more lubrication, the transmission may be on the fritz, or worn out universal joints.
It can be difficult to pinpoint the real cause of the sound since the noise under a car tends to reverberate throughout the entire body. To be sure, this sound should be investigated by a qualified mechanic.
