Listen… 5 Warning Sounds Your Car May Be Making

, , , , ,

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.

engine noise warningsTo 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.

Stop. It’s Time for a Brake Inspection

, , , , ,

We hate to hear stories of vehicle accidents, especially when, with a little preventative maintenance, they could have been avoided.

When a car hit a curb near 19th St. and Clarke Ave in Des Moines on Thursday morning, the impact launched the car into the air, then rolled and hit a tree.  Investigators haven’t determined an official cause for the crash, but officers first on the scene reported “minimal skid marks.”

When you step on the brakes to slow down, the pedal should feel firm under your foot. The harder you press on the pedal, the firmer the brakes should feel. And if you’re in a situation that requires a sudden stop, mashing down on the brake pedal will feel almost as firm as stomping your foot on the ground.

What if your brakes don’t feel firm when you slow down or need to make a sudden stop? If you’re like most people, that sensation can leave you feeling a little anxious. When you press on the brakes, you want to know without a doubt that they’re going to slow your car down.

Getting your brakes checked periodically can be a lifesaver. In many cases, simple and inexpensive repairs and preventive maintenance can keep your brakes in working order for many miles. Check out these three warning signs that suggest a problem with your brake system:

  1. Brake pedal quickly goes to the floor when you press it. This may be a sign that your brake system’s master cylinder is no longer pressurized and could have a leak.
  1. Pressing the brake pedal feels soft or has less resistance than normal. It’s often caused by low levels of brake fluid.
  1. Braking feels rough. Worn brake pads and uneven rotors can make braking feel rough and bumpy. You may even hear screeching or grinding noises coming from the wheel hub where the brakes are located if these parts are worn or warped.

If you’re wondering if your brakes are working properly, don’t wait to find out until you’re faced with making a sudden stop to avoid an accident. And even if you think your brakes are fine, but it’s been 30,000-plus miles since your brakes were inspected, is a good idea to have them checked out.
