Purpose and Function in the Cooling System

The radiator fan in the Audi A4 B8 diesel engine is responsible for forcing airflow through the radiator core, especially in urban conditions, at low driving speeds, or under high load of the power unit. A properly functioning component ensures:

• maintaining stable operating temperature of the diesel engine,
• relieving the cooling system during traffic jams,
• increasing the thermal safety of the entire powertrain.

Thanks to its compatibility with the specific A4 B8 generation, the fan works with the factory housing, radiator, and control system, which translates into predictable behavior of the cooling system.

Compatibility and Technical Specifications

The presented fan is dedicated to Audi vehicles with a Diesel engine. Proper matching to the A4 B8 engine version and body type allows for maintaining the factory airflow geometry and correct mounting point placement.

The component has an assigned OEM part number and related interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration. In practice, this means the possibility of precisely selecting the fan for the existing radiator and electrical system without the need for modifications.

Performance Characteristics and Installation Benefits
