The causes of steering pump noise fault are: 1. Air entering the steering system; 2. Improper fit between the flow control valve hole and valve core; 3. Dirt jamming between the safety valve cone and valve seat sealing surface; 4. Non-circular sealing surface or presence of gaps. The automotive steering pump is engine-driven to convert low-pressure oil from the oil tank into high-pressure oil delivered to the steering control valve. The functions of the steering pump are: 1. As the power source of hydraulic power steering system, it reduces driver operation intensity and improves vehicle maneuverability; 2. Controls internal pressure of power steering pipelines through pressure safety valve to ensure steering system safety; 3. Regulates steering system flow through flow control valve to maintain proper steering feel during high-speed driving.

Where is the hood?

The hood is located above the engine compartment. The car engine is the motor, and its position varies depending on the vehicle layout. For commonly seen sedans, the engine is positioned at the front of the vehicle, in the first compartment of a three-box car, so the hood (engine cover) is situated above the front body. Some vehicles have rear-mounted engines, where the engine is located in the trunk area, making the trunk lid the hood. Additionally, some supercars feature mid-mounted engines, with the hood being a small flat section behind the driver. The hood is typically made of rubber foam and aluminum foil materials, which help reduce engine noise while also insulating the heat generated during engine operation, effectively protecting the paint on the hood's surface and preventing aging.
