Detailed Description

Four Seasons 76318 is a radiator fan assembly engineered for direct replacement on BMW cooling systems. It is built with a plastic shroud, rigid plastic blade, and electrical motor assembly to restore airflow across the radiator. The unit mounts in the radiator fan location and uses an OE-style mounting pattern for service on 2004-2007 BMW X3, 2008-2010 BMW X3, and 2006 BMW X5 applications. This part cross-references A11454 and FA70738 for the same application.

What It Helps Resolve

• Overheating caused by a failed radiator fan motor
• Reduced airflow through the radiator at idle or low speed
• Cooling fan noise from worn electrical fan components
• Intermittent fan operation from connector or terminal wear
• Replacement needs after damage to the fan shroud or blade assembly

Installation Notes and Tips

Verify OE mount alignment, connector style, and radiator fan location before installation. This assembly uses a 3-wire lead with connector and does not include mounting hardware. The fan clutch is not mounted within the assembly, so confirm the vehicle’s cooling system configuration before service. For BMW X3 and BMW X5 applications, compare the original unit’s dimensions and terminal layout to the replacement part before final installation.

Quality Assurance

Four Seasons 76318 is an OE replacement, performance-rated cooling fan assembly intended for direct-fit service on listed BMW applications. Confirm vehicle year, model, and cooling fan configuration against the fitment data before ordering.
