Diagnosing Automotive Problems

Diagnosing-Automotive Problems Bу Listening Tо Yоur Car's Noises

If your vehicle is working properly, it does so without attracting attention. So when strange noises occur, they come out. You can hear pings, whistles and chirps coming from your hood; You may hear squeaks or scratches coming from the brakes; Or maybe you hear a clicking sound that is almost impossible to diagnosing automotive problem by listening to the engine.

You'll be surprised at the number of problems you can solve by simply hearing the sounds coming from your car. In this article, we give a brief overview of the most common. While future leadership can not help diagnose a faulty generator or catalyst, it will highlight many other issues.

Screeching Frоm Beneath Thе Hood

You turn the key on the ignition, you hear your engine come to life, then you hear a shrill scream. The problem may be due to a loose drive belt. Long ago, most vehicles had multiple belts that worked with accessories and components. For example, your water pump had a belt; his generator had a belt; his air conditioner had a belt; and his power steering pump had a belt.

Nowadays, most vehicles are built with a single serpentine belt that powers these and other components. If he is lost, he can be removed from his position. This causes squeaking.

Whistle under the hood

The whistle is easy enough to loosen. The culprit, however, is again a loose or torn pipe. The cooling system of your vehicle, especially the radiator, is compatible with many of these rubber hoses. Often the rubber deteriorates and begins to crack. When that happens, you'll hear a hiss.

Because these hoses are compatible with the cooling system, they are essential to the health of your engine. Fortunately, they are relatively cheap and easy to replace.

Ping in the engine

This is a problem that can be triggered by several factors. First, the octane rating of the fuel in your engine may be too low, resulting in unpredictable or bright ignition. Second, the bad timing can ping. This often happens when one or more spark plugs are triggered soon. A third factor is your cooling system. If you can not control the temperature around your engine, the increase in heat can cause this noise.

If you hear a ping, use higher octane fuel. Also check the coolant level and its temperature (observe the coolant meter). If the level is correct but the temperature is above normal, a mechanic must inspect the cooling system.

Beat the street quietly

This noise can be frustrating because it only happens when your vehicle is moving and tends to disappear when it stops. It's a pulsating sound, like a heartbeat. It occurs faster than acceleration and slows down with decreasing speed. The problem usually lies in the tires.

From time to time, a foreign object is caught in the steps and applause. More often it is caused by a crack or bubble that has developed in the rubber (often the sidewall). If the noise is not caused by an object stuck to one of the rungs, the best solution is to replace the tire.

Squeaking or scratching the brake system

If you hear a squeak of your brakes, do not assume that the brake pads are worn and need to be replaced. Squeaking can also be caused by vibrations on new brake pads. Let them check if they are in good condition. If they are worn out, replace them.

A sound of scratching or grinding indicates an unbeatable problem. Noises usually occur when the worn brake pads rub against the rotors. The pills must necessarily be replaced. But if you wait a long time, you risk damaging the rotors. Replacing them is much more expensive.
