Common Car Noises and their Diagnosis

Common Car Noises and their Diagnosis

Driving a car can be as common as breathing for some. Irrespective of whether a car is being driven on not, the driver should be aware about car noises that are indicative of trouble. Basic awareness is quite helpful in explaining the problem at a mechanic, or when stuck in an unknown area. Visits to mechanics may not be required in every case. The top car noises and their diagnosis have been described below:

  • Squealing Noise on Turning the Vehicle: A vehicle that is low on power steering fluid is likely to emanate a squealing noise when it is turned. It is possible to check the amount of power steering fluid in the reservoir, found after opening the hood. In case this fluid goes low on a regular basis, it is important to visit a reputed mechanic. On the other hand, if the squealing noise is being heard upon starting the vehicle, it means there are worn or loose accessory belts around air conditioning compressors and alternators or power steering pumps.
  • Groaning Yawn on Vehicle Being Turned: This noise can turn into a serious issue if it is not diagnosed in its initial stages. With time, this problem carries the potential of making the driver lose control of the steering wheel. This sound can be experienced because of a failing power steering assembly. Once again, the best way to get it rectified would be to take the vehicle to a suitable mechanic.
  • Grinding Noise Upon Shifting Gears: This is one of the common noises heard by many vehicle owners. The problem here is either a clutch with improper tuning or a clutch that is nearing the end of its life. Not solving this problem can result in the transmission getting damaged as well.
  • Engine Knocking: This is a common noise in a place where low quality of fuel is being sold. This sound is heard because of incomplete fuel combustion. Engine knocking can result in a mileage lower than what a user might be used to. There can be many reasons due to which knocking takes place, where inferior quality fuel is most common. This results in a poor fuel-air mixture that leads to engine knocking.
  • Popping Within the Engine: Popping is a clear indicator of the car asking its owner for servicing. It also occurs due to a variety of reasons, among which a clogged fuel filter can be one. Even bad spark plugs can cause the sound. At times, popping can be heard even when engine oil in the vehicle is low. Explaining the problem to the mechanic would be helpful in dealing with it in an effective manner.

Always remember that driving a car does not only mean moving it from point A to point B. It is important to put the ears to good use and listen to the car carefully. Knowing about the noises given above will help determine which of these are urgent and which are not. Remember that the car has several mechanical parts, and basic awareness will help isolate the problem to relevant parts.
