Air Deflector / Air Guide Cover

1. Basic Part Information

• Part Name: Air Deflector / Air Guide Cover

• Applicable Models: Mainly suitable for Sinotruk HOWO TX and HOWO T5G series heavy-duty trucks.

• Appearance Features:

  • Shape: Streamlined vertical structure with specific curves and cutouts at the top. Features mounting clips and fixing holes on the sides.

  • Color: The image shows both red (matching Sinotruk's classic paint scheme) and white/light gray versions. Actual finish depends on the specific vehicle's color.

  • Material: Typically engineering plastic (e.g., ABS) or fiberglass, offering good strength and weather resistance.

2. Function & Role

• Airflow Optimization: Mounted at the front of the vehicle (usually above or alongside the bumper), the air deflector directs oncoming airflow — reducing aerodynamic drag and improving fuel efficiency.

• Cooling System Protection: Proper air deflection ensures adequate cool air reaches the radiator for effective engine cooling, while preventing turbulent air from directly hitting the cab sides — reducing wind noise.

• Aesthetic Integration: As an exterior trim part, it fills the gap between the bumper and the body, giving the front end a fuller, more cohesive appearance.
