4 Car Noises That Mean You Should Visit an Auto Mechanic, Florissant, Missouri

As a general rule, you shouldn’t hear more than a dull hum or roar from your vehicle while you drive it. However, there are several unusual sounds your car might make, and if you hear them, you should visit an auto mechanic. Here are a few strange noises your car might make and the problems they could indicate. 

4 Car Noises & What They Mean

1. Hissing

Hissing or even sizzling noises might point to dangerous engine fluid leaks. You could even observe smoke or steam rising from beneath your hood, due to oil, coolant, or steering fluids coming into contact with hot mechanical components. Prevent damages and fire risks by contacting an auto mechanic immediately. 

2. Thumping

auto mechanicWhen you notice thumping noises while your vehicle is in drive, you might have worn-out tires or faulty axles. In some cases, these sounds could indicate brake failure, which makes you more likely to get into an accident. Stay safe by scheduling auto repairs as soon as possible. 

3. Knocking

When you hear knocking noises while you accelerate, the problem most likely stems from the engine or belt tensioners. There might also be issues with the belts, rods, and pistons, which require immediate attention from an auto mechanic to prevent costly damages. 

4. Squealing 

Squealing and scraping sounds usually indicate brake trouble. It’s even possible that your brake pads have worn down entirely, causing the metal components to grind against one another. Prevent the need for new brakes by getting pad replacements.
