What Different Car Noises Mean

Very rarely does your car malfunction suddenly. It might seem sudden if you have not noticed signs of a problem, but usually a problem tends to build up over time. There are some occasions, often due to outside forces, in which your car does break down abruptly. Usually there are some warning signs of your car malfunctioning. Those signs can be either noises or operational peculiarities. Here are some of the noises or aberrations that signal there’s a problem with your car and what they actually mean.

High-Pitched Whining

If you start your engine and instantly hear a high-pitched whine that lasts for a minute or so, you could have a belt issue. Most cars in the 21st century have two main belts: a fan belt and a serpentine belt. The fan belt uses the turning of the engine to turn a fan. When that belt becomes stretched or dries out, it can start to slip. At the incredibly high speeds of your engine, such slipping can manifest into a high-pitched whine. It tends to go away since the heat of the engine causes the rubber to become a little more elastic and adhere better. If you seek car servicing in Leicester at the first sign of whining, you can avoid bigger problems in the future.

Squealing When Braking

To stop your car, the brakes apply pressure to a disc that is connected to your wheel. The friction of the application stops your car. However, such friction also wears down the rubbery substance of the brake pads. Therefore, manufacturers install a material that warns you when the brakes are running down. That material will squeal when you apply the brakes. In some cases, it’s more like a grinding sound.

A brake pad replacement is a quick and common repair. If you let it go too long, you can damage your rotors and harm your braking ability, which is a much costlier repair.

Grinding When Shifting

If you have a manual transmission, your car may begin grinding when you shift into certain gears. That’s a sign that your transmission is either misaligning certain gears, or it needs a fluid flush. If you have an automatic transmission, such grinding can mean the same thing as well. However, automatic transmissions are much more complex than manual ones and may require more work. It’s also much more difficult to avoid problematic gears with an automatic transmission.

Knocking

If you hear your engine knocking or if you hear your exhaust pipe backfiring, it means that petrol is not combusting fully in your cylinder. It can then combust again later on. That can be a sign that your spark plugs are not operating properly. It’s also a potential problem depending on where the secondary combustion is occurring. You should initially check to make sure you are using the right octane fuel.

A higher octane fuel combusts at a lower temperature, and you could be using the improper fuel. If you are not using the right fuel, you need auto repair done quickly. That could be a small problem you should not allow to grow.

These are just a few of the common indications of future problems with your car.

Some Common Collision Repairs

In the past, car design philosophy stated that cars should be made of unbending and unbreakable steel. They were designed to resist any damage. While that might have made for much stronger cars, it also led to more injuries. Recent research is now indicating that the car needs to absorb as much of the collision impact as possible. If you crash your car and the bumper crumples, it will dissipate a lot of the force. Therefore, cars are now designed with crumple zones and impact zones that can be destroyed in even a fairly non-serious collision, and you need to keep a good collision repair specialist in mind if such an accident occurs.

Bumper Damage

Damage to your bumper is incredibly common in just about every kind of crash. That’s what they are designed to do. Bumpers are made so that they will take the brunt of the force of a collision. Modern bumpers crumple almost completely when they hit something, so a bumper repair is one of the most common Mercedes-Benz smash repairs in Melbourne. If you get into any kind of collision that takes place on the front or rear of the car, you’ll likely need to get your bumper repaired.

Frame Damage

Your car is built on a frame. There are many different car frame designs. The frame, unlike the rest of the car, is designed to remain rigid even in case of a collision. If the frame of your car bends or cracks, your entire vehicle is compromised. You’ll need to have extensive repair work done to your car. To determine whether or not you have frame damage, you’ll need to take it to a collision repair specialist who will be able to inspect your frame for any damage. In addition to the obvious damage, he or she will be looking for signs of weak points as well. A frame doesn’t necessarily fall apart cleanly. Sometimes, a collision might just weaken a few joints.

Rust Vulnerabilities

When you have a collision, your frame, bumpers, engine mount, and much more might be damaged in minor ways. For example, a floor panel could be scratched or slightly bent by the crash. It might seem like a small problem but it’s actually fairly significant since that could indicate paint has flaked off at the site of impact. Paint or sealant seals out moisture to keep the metal parts from rusting. If that paint is flaking off, rust could set in. Over time, rust and/or corrosion will degrade the quality of the steel.

Paint Matching

Matching paint is incredibly difficult for a mechanic, which is why you need a specialised collision repair shop. Matching paint involves more than just finding the same brand and colour. Over time, paint changes colour as it fades or oxidises. Since the colour of the paint changes, it will be obvious if the mechanic simply paints it with a brand new can of that original colour. The new paint has to be mixed to match the colour in its current state. Such a task requires a collision repair expert.
