Airtex Automotive Division 64-54-8-380-780 Auxiliary Fan Assembly with Shroud for A/C Condenser

The Airtex Automotive Division 64-54-8-380-780 is an auxiliary fan assembly with shroud designed as a direct replacement for BMW E39 5 Series air conditioning systems. This electric pusher fan mounts in front of the radiator and is engineered to force air through the A/C condenser and main radiator, providing critical cooling when the vehicle is in traffic or when air conditioning is activated.

Key Features:

• Complete assembly includes electric fan motor, fan blade, shroud, wiring, and connector plugs for direct bolt-on installation
• Electronically activated when air conditioning is engaged, not belt-driven
• Provides additional cooling capacity to prevent overheating in low-speed and idle conditions
• Direct replacement for BMW OEM part number 64548380780
• Designed to meet or exceed OEM specifications for fit and performance

This auxiliary fan assembly is a common wear item that can fail due to motor burnout or blade damage. Symptoms of failure include rising engine temperatures, poor A/C performance, or the fan failing to engage when the air conditioning is turned on. Replacing a failed auxiliary fan assembly restores proper cooling system function and ensures consistent air conditioning performance.
