Some Common Car Sounds and What They Mean

- in Maintenance & Repair

Your car is made up of thousands of different components and hundreds of moving parts. On any given day, some of them can malfunction. These parts can malfunction because of user error or simply due to the stress of driving. Typically, vehicle problems are accompanied by a few symptoms. Smaller problems such as problems with sensors or smaller components don’t always have sounds. However, newer vehicles will have OBD II codes that your engine will produce. These codes will indicate what is wrong with your vehicle. If you want to buy an OBDII scanner, you can read the codes yourself; typically, you can just go to an auto shop where they will read them for you. The problems that make noises are sometimes more troubling. Here is what these types of problems can mean.

Squealing When You Start the Car

If your car starts squealing when you start the car but then dies down after a few minutes, it’s likely a problem with your fan belt. Your fan belt is connected to the engine and to the fan; it turns when the engine turns on. It runs the alternator and many other components. If the fan belt is not as tight as it should be, it could slip somewhat, which could lead to the squealing you hear. It dies down after a few minutes because the rubber of the belt heats up enough to form a tighter grip. A fan belt problem is a common reason for servicing a car in Leicester. If the fan belt is not in great shape, it could affect the alternator, which could affect the battery and create a whole host of other problems.

Squealing When You Press the Brakes

When you press the brakes, you should not hear anything. However, if you hear squealing, grinding, or some other sound, it’s usually an indication that you will soon need a brake job. You’ll ultimately need new brake pads. The pads stop your car by grabbing the rotors and creating friction. That means they will wear down over time. Brake pad manufacturers typically install some kind of element that will make noise when the brake pads need to be replaced. That means the pads should be replaced as soon as possible when you hear the noise.

Knocking Under the Hood

If you hear some kind of bumping or knocking under the hood, it could mean that the petrol is not combusting fully when you are driving. That is commonly a problem with older vehicles. You should try a higher octane of fuel first. If that doesn’t work, it means that something in your engine is not working as it should. There are many reasons why fuel might not be combusting fully; you most likely need to get to a mechanic soon with this problem.
