Why is there a loud sound in the engine compartment of the car?

1. The car engine compartment has a loud blowing sound because there is a fan in the air intake of the car engine. Engine radiator, also known as engine water tank, is a key component of a water-cooled engine cooling system. Cooling the engine through forced water cycle is a heat exchange device to ensure the continuous operation of the engine within the normal temperature range.

2. The car engine compartment has a loud blowing sound because there is a fan at the air intake of the car engine. Engine radiator, also known as engine water tank, is a key component of a water-cooled engine cooling system. It is difficult for ordinary car owners to distinguish which are faulty and which are reasonable.

3. The belt is not elastic enough: the engine makes a squeaky sound at work. Leakage in the intake and exhaust pipe: At the intake and exhaust pipe, the gas will leak from the exhaust pipe and make noise. Poor fuel quality: causing violent vibration in the engine to make noise.

4. The problem of loose parts. Some parts in the engine cabin, such as the door cover and intake pipe, are loose. When the vehicle is driving, it will collide with the cabin and make a sound. It can be solved by reinforcement.In addition, when the screw used to fix the engine is loosened, it will also cause the engine to shake and make a strange sound.

5. The sound of the wind is made by the rotation of the water tank fan. Now the water tank fan of the car does not rotate all the time. It is controlled by the thermoster. When the temperature is detected that the water temperature is too high, the water tank fan begins to work to strengthen heat dissipation. When the water temperature drops, the fan does not turn. If the fan is turned off during operation, the fan will still rotate for a while to continue to dissipate heat.

How to clean the engine cabin
