What features does the Cooling Fan Assembly have regarding its operation on the BMW X3?

X3 models have an electric cooling fan placed on the side of the radiator, with two types designed for auto- and manual-transmission vehicles. The fan is controlled by the engine control module (ECM) at the output final stage which is located at the side of the fan housing beside the fan motor. It is operated through a pulse width modulated signal and the wiring of the fan circuit is protected by a high amp fuse. Control of the electric fan involves inputs to the ECM such as outlet of the radiator temperature, estimate of the catalytic converter temperature, vehicle speed, battery voltage and estimate of pressure of refrigerant. In the absence of ignition, the electric fan runs at a low rate, which is at 20% then off to establish diagnostics on the vehicle. Since the fan has stored rpm values in the fan output stage, the voltage generated during the decelerating stage of the fan must be appropriate for it to function. In the case that a cooling fan fault is stored in the ECM fault memory, it is advisable to check that the fan is not stuck and can rotate. In case the air conditioning is switched on, the electric fan does not start to rotate immediately, and after the engine stops, the fan may rotate at different speeds for up to 10 min, depending on calculated temperature of the catalyst.

BMW X3 Cooling Fan Assembly

Engine temperatures are therefore kept in check by the BMW X3 Cooling Fan Assembly, which sucks in fresh air through the radiator any time it may lack natural airflow. Positioned just behind the grille, the Cooling Fan Assembly consists of a contoured shroud, multi-blade fan and motor that operate together to draw air across the radiator fins, cooling the heated coolant before it flows back into the engine. At highway speed, the car uses ram air, but in traffic or at idle, the Cooling Fan Assembly becomes the primary mover of air, which prevents the engine from overheating and maintains engine performance. Early versions in the first BMW X3 generations still had belt-driven mechanical fans on certain engines with a clutch that spun faster as the under-hood heat went up. Newer X3 models switched to an electric Cooling Fan Assembly that is operated by sensors and allows variable speed operation, faster response and better fuel efficiency because the Cooling Fan Assembly is decoupled from engine rpm. This evolution represents the commitment to combine reliability with efficiency by BMW, and regardless of the version, each design has mounted the Cooling Fan Assembly close to the radiator to ensure maximum airflow and the use of durable plastics for the air channels.

If you are looking for OEM BMW X3 Cooling Fan Assembly, we highly recommend to shop with us. Not only do we offer budget friendly prices, but we also provide fast delivery. In addition, we have a hassle-free return policy on all genuine BMW X3 Cooling Fan Assembly that come backed by the manufacturer's warranty.
