10 kinds of “calls for help” you might encounter when you go home during the Spring Festival

【The owner's family car knowledge】Impact sound, a heavy metal iron impact sound, is likely to be caused by severe wear and tear of the engine mount for a long time. A crash occurs when the engine speed changes, but it may also be caused by damage to the front and rear suspension of the car, or too little transmission fluid.

Tap sound:The sound is similar to a heavy knock, but the sound is small. When this kind of sound appears, the car mainly thinks about whether it uses low-quality gasoline. If it uses low-quality gasoline, it may also make a popping sound.

Tick:It may be that the direction of the drive shaft is broken, or it may be caused by the small stones in the tire hitting the tire or the bending of the fan blades.

Hiss:Like a balloon leaking, most of the problems are caused by the air conditioning or cooling system. If the cooling system fails, liquid can be seen on the bottom of the car. In addition, this kind of sound can also be caused by a large tire leak or a leak in the engine vacuum chamber.

Heavy knock: Like a dull knock on the door, this situation is mostly caused by the internal engine of the engine, which is probably caused by the aging of the vehicle, and damage to the bearings or engine valves can also be caused.

Howling:It mostly occurs when the car is turning. It may be that the fan drive belt is loose or worn, and sometimes the tires are not inflated enough to cause this sound.

Buzzing: This sound is similar to the sound made by a bee. It is likely that a certain part is loose. The plastic or metal parts at the bottom of the engine and the fixing brackets of the air conditioner or compressor are the most common.

Rumble: A scream of "Woo Wang..." is made from the car. It is likely that the ball bearings in the wheels, compressor, or water pump are broken, and it is also likely that the air conditioner or compressor is malfunctioning.

Transposition sound: Mainly the uncoordinated sound made by the aging of the motor.

Scream: Very harsh, usually because of a problem with the brakes.
