What Causes the Loud Clicking Sound from the Chassis After Parking?
1 Answers
After parking, the loud clicking sound from the chassis is caused by the thermal expansion and contraction of metal components such as the exhaust pipe. This sound usually disappears on its own after a few minutes and is particularly noticeable in winter, which is a normal phenomenon. However, there are also some abnormal clicking sounds, such as those caused by aging or loosening of engine mounts or an overly rich air-fuel mixture. The automobile chassis consists of four parts: the transmission system, the running system, the steering system, and the braking system. Its functions include supporting and installing the car engine and its various components and assemblies, forming the overall shape of the car, receiving the power from the engine to enable the car to move, and ensuring normal driving.
