When you start up your car, you want to hear your engine running smoothly and quietly. And when you leave the house in a rush to get to work or head out of town on vacation, the last thing you want to hear some unfamiliar sound coming from your car.
To the untrained ear, any unfamiliar or new sound coming from under the hood can seem like impending doom for your vehicle. While some sounds may indeed be a telltale sign of a serious problem, some sounds are early warning signs that are inexpensive to fix. Here are five common sounds you might hear coming from your car, along with what to do about it.
1. Clicking and Tapping
It’s a warning sound you’ll notice right away, especially when your car has been running smoothly. Hear clicking or tapping, and you’ll probably roll down your window while driving to get a closer listen to the sound. Chances are pretty good it’s either a valve problem related to a worn part, or low oil pressure. Make sure the engine has enough oil, and if you can’t find the source of the sound, schedule an inspection.
2. Loud Knocking Noises
If you hear this warning sound, stop driving as soon as possible. Loud knocking sounds usually indicate a major issue with a part inside the engine. Continue driving, and the problem can lead to serious engine damage that might only be repairable by replacing the engine.
3. Rattling and Whining
If your car has a cam shaft belt problem, you might notice a rattling or whining sound when you step on the gas. The camshaft helps open and close valves in the engine, and it’s a critical component for engine performance. If the cam shaft belt is loose, poorly aligned, or slips, it can cause a rattling or whining noise, particularly when you accelerate. A problem with the cam shaft is best handled by a trained mechanic.
4. Squealing During Acceleration
When an engine fan belt is loose or slips, it can make a terrible squealing sound. It’s most often caused by an aging belt that has developed cracks and is beginning to loosen. The engine fan belt is also called a serpentine belt. When the rubber teeth of the belt no longer grip the pulley tightly, they can drag across the pulley and make the telltale squealing sound. The belt either needs to be tightened to eliminate the squealing, and in most cases usually needs to be replaced.
5. Grinding Sounds
If you hear grinding sounds, it may not be coming from the engine. Let’s hope not (grinding sounds coming from the engine usually indicate a very serious problem). Roll down your window and listen carefully. The grinding sound may be coming from your brakes. Worn out brake pads and rotors can make a grinding sound. Hear this warning sound, and it’s a good time to get a brake inspection.
