Engine Cooling Fan Assembly

The Conti 17117590699 is an engine cooling fan assembly crucial for your BMW's cooling system. This component is responsible for maintaining optimal engine temperature by ensuring sufficient airflow through the radiator, particularly vital when the vehicle is idling or moving at low speeds. The assembly comprises a fan, shroud, and motor, and operates at 400W with a single fan and PA+GF fan blade material. Electric cooling fan assemblies can fail due to issues with the integrated fan controller or motor. Modern systems utilize a PWM signal to vary fan speed, and failure of the controller will prevent the fan from engaging. Symptoms of a failing cooling fan assembly include engine overheating, especially in traffic, and a decrease in air conditioning performance. If the fan is not turning on, even with a hot engine, it indicates a potential failure. This part replaces OE numbers 17117590699 and 17427523259, and MFG number 3142360012. This cooling fan assembly is designed to fit various BMW models, including the 1 Series (E82, E87), Z4 (E89), and 3 Series (E90, E91, E92, E93) with engines such as the N52 and N52N. Specific models include the 128i, 325i, 325xi, 328i, 328i xDrive, and 328xi, among others. Fitment details may vary based on specific vehicle year and transmission type.
