What causes the buzzing sound in the Haval H6 power steering pump?

The buzzing sound in the Haval H6 power steering pump is caused by either a damaged pump or insufficient power steering fluid. The power steering system primarily assists the driver in adjusting the vehicle's direction, reducing the effort required to turn the steering wheel. Power steering also plays a role in the safety and fuel efficiency of the vehicle. The specific reasons for the power steering pump noise are as follows: 1. Leakage in the power steering pump, resulting in low fluid levels, which causes noise when turning the steering wheel; 2. Poor lubrication of the power steering pump during cold starts, leading to internal wear and noise; 3. Loose installation of the power steering pump, causing noise during operation.

Why is the ambient light not working?

Ambient light not working is due to a car circuit failure. Here are the specific details about ambient lights: 1. Activation: Ambient lights turn on when the engine is started and the surroundings are dim. 2. Function: They completely transform the appearance of the car interior at night, enhancing brand recognition. They ensure the interior is not too dark while driving, creating a pleasant driving environment and helping to prevent driver fatigue, thereby improving safety. 3. Modification: When modifying ambient lights, since it involves altering the car's original electronic circuits, it is essential to choose a reputable modification shop to avoid potential safety hazards due to quality issues later on.

What is the function of the valve spring?

The function of the valve spring is to overcome the inertial force of the valve and its transmission components during the valve closing process. Below is an introduction to valve springs: 1. Purpose: To prevent gaps between transmission components caused by inertial forces, ensuring the valve promptly seats and tightly fits, preventing valve bouncing during engine vibration which could compromise its sealing. 2. Tool Introduction: The valve spring is located between the cylinder head and the spring seat at the end of the valve stem. Its function is to ensure the valve tightly fits against the valve seat or valve seat ring when closed, and to overcome the inertial force generated by the valve train during valve opening, keeping the transmission components always under cam control without disengaging from each other.

What is the difference between slush molding material and hard plastic?

The difference between slush molding material and hard plastic lies in their hardness. Here is additional information: 1. Internal materials: Slush molding has a foam layer inside, making it less hard than hard plastic. The materials used in slush molding are different, resulting in higher manufacturing costs compared to hard plastic. The surface layer of slush molding material is made by heating polypropylene styrene, with a foam layer in the middle, while hard plastic is made from plastic materials. 2. Smoothness: The car dashboard uses hard plastic decoration. To save costs, the hard plastic dashboard has a stronger reflective texture and is smoother. If slush molding were used, the dashboard would not be as smooth.
