What this part does
The radiator cooling fan draws ambient air through the radiator and air conditioning condenser when the vehicle is idling or moving at low speeds. Mounted directly behind the radiator assembly, it relies on a built-in control module that receives pulse-width modulated (PWM) signals from the engine computer to adjust fan speed continuously based on coolant temperature and AC system pressure. When this unit fails, common symptoms include engine overheating during stop-and-go traffic, weak air conditioning performance at idle, or the fan running constantly at maximum speed due to a module internal fault. A scan tool will typically reveal thermal management or fan control circuit codes.

Before you order
BMW uses several different fan wattage ratings across the 7 Series chassis depending on specific equipment packages, such as hot climate versions or heavy-duty cooling options. You must match the 11-digit OEM part number on your original fan shroud to ensure the integrated control module will communicate correctly with your vehicle. After installation, any stored thermal management faults in the engine control unit must be cleared, and a functional test using diagnostic software is recommended to verify the DME is commanding the fan properly.
