What Causes Noise Inside the Car?
2 Answers
Noise inside the car can be attributed to the following specific reasons: 1. Buzzing noise when idling: When the car is idling and the water temperature is normal, the buzzing noise may be caused by the electric fan used for radiator cooling. 2. Buzzing noise at low speed or during gear shifting: This is mainly due to excessive clearance between the piston and the cylinder wall. Details on car engine usage: 1. Antifreeze: Engine antifreeze needs to be checked regularly. In winter, it is necessary to replace the antifreeze in time to avoid pipe rupture caused by excessively low temperatures. Never use water instead of antifreeze, as it can freeze easily. Tap water contains impurities that can form scale, clog pipes, and hinder smooth circulation. 2. Engine oil: Engine oil should also be checked during routine maintenance. Replace the oil according to different driving environments and habits, and ensure its quality to avoid adding inferior oil.
There could be several reasons for noises inside the car. I often encounter minor rattles caused by loose interior trim while driving, such as door panels or the center console clattering on bumpy roads. The seatbelt adjuster or seat tracks might also produce friction sounds if not properly secured. More serious issues involve mechanical components, like worn shock absorbers or stabilizer links in the suspension system, which can creak when turning or going over bumps, or aging wheel bearings that emit a humming noise. Wind noise is also noteworthy—aged window seals may whistle at high speeds. I recommend first checking interior fasteners, trying to close windows tightly and driving for a while to locate the sound source. If the noise persists, visit a professional shop to diagnose the suspension system to prevent safety hazards, as driving concentration could be affected.
