Land Rover Part Number: ERR3439 - 17 Inch 11-Blade Cooling Fan - EFI V8
ERR3439 is a 17 inch, 11-blade cooling fan for EFI V8 engines. Fitted to the engine cooling system on vehicles using the 4.0 V8 EFI with a viscous drive coupling, the axial fan moves air through the radiator and across the engine bay to assist temperature control. The 11-blade design and 17 inch diameter are selected to provide a balance between airflow and driven load when mounted to the viscous coupling; the fan is finished in black and matches the viscous drive interface used on Rover V8 applications. When replacing, match the original blade count and diameter to maintain the correct airflow characteristics for the viscous drive arrangement. Use the compatibility data below to confirm fitment against your V.I.N.
