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.

Timing Belt Replacement Can Save You Money

, , , ,

If you’ve driven your car more than 70,000 miles, there’s a good chance a the timing belt is over-worn and a breakdown is imminent. If it breaks before being replaced, your engine could be lost and repair costs could be staggering, but if the timing belt is replaced in your vehicle before it breaks, it’s a relatively low-cost repair.

replace your timing belt des moinesJust about anyone can inspect a timing belt. It’s the thick-toothed rubber belt that helps power the engine and control the camshaft, crankshaft, valves, and pistons. Periodically checking the belt for wear can reveal small cracks in the rubber or missing teeth that can hinder engine performance.

Unfortunately, too many drivers fail to inspect the timing belt or have it replaced before it’s too late. If it snaps while you’re driving, you’ll be stranded and your car will need to be towed. If you’re lucky, replacing the timing belt will get you back on the road. But in many cases, a broken timing belt damages the engine too. And that can be expensive to repair.

Timing Belt Replacement Recommendation
Most car manufacturers recommend replacing the timing belt every 70,000 to 110,000 miles. Remember, in most cars the timing belt is a wearable part made of rubber. It won’t last forever with all the friction it endures along with hot and cold temperatures. Inspecting your timing belt and having replaced before it breaks can save you thousands of dollars. When your timing belt is replaced as recommended, it typically only costs a few hundred dollars.

Warning Signs of a Bad Timing Belt
Sometimes a timing belt can reach the end of its life without warning. One minute you’re driving down the road, the next minute your engine is running but you’re not going anywhere. It’s a good reasons to have the timing belt replaced based on the recommended guidelines before it’s too late. However, there are a few warning signs to be aware of that are telltale signs of a timing belt about to break:

  • Trouble starting the car. If you can rule out the battery, starter, or lack of fuel, a bad timing belt may be the problem. A poorly functioning timing belt can interfere with the car’s ignition timing.
  • Thick smoke from the exhaust. If your car begins emitting thick smoke from the tail pipe and it progressively gets worse, it’s an indicator that fuel in the engine isn’t being used efficiently. Poorly functioning valves linked to a bad timing belt may be to blame.
  • Shaking or vibrating engine. When the timing belt in a car begins to age, gets stretched out over time, or has missing teeth, you may notice more shaking or vibrating from the engine.
  • Hot engine, leaking fluids. If you’re not taking care of your car, the engine could be running hotter than it should be or it could be leaking fluids. These conditions can further weaken and damage the timing belt.
