Show original supplier description
The BMW Engine Cooling Fan Assembly, part number 17428508253, is a genuine OEM replacement designed to integrate seamlessly with your vehicle's cooling system. This assembly includes both the fan blade and the motor, ensuring efficient airflow through the radiator to maintain optimal engine temperature, particularly during low-speed driving or idling. This fan assembly is crucial for preventing engine overheating, which can lead to significant damage. It also plays a role in the performance of your air conditioning system by helping to cool the condenser. Symptoms of a failing fan assembly can include rising temperature gauges, especially in traffic, and reduced AC performance. This specific fan assembly is rated at 850W and replaces BMW part number 17427802944. It is specifically designed for the 3 Series with turbo diesel engines, including the 335d model. Additionally, it fits the BMW 1 Series M (2011) and the 335is (2011-2013). While it may physically fit other BMW models, such as the 135i or 335i, there could be performance issues due to wattage differences (850W vs. 600W factory fans) and potential problems with the PWM signal control, possibly requiring coding for optimal performance.
