Detailed Description

Dorman 620-066 is an engine cooling fan blade engineered for select Dodge Ram 2500 and Ram 3500 trucks from 1994-2002, along with 1989-1993 Dodge D250, D350, W250, and W350 models equipped with an intercooler. The thicker steel blade design helps reduce flexing under operating load, addressing a common failure point in original clutch fan blades that can crack over time. This part cross-references SKP SK959920 for the same application.

With a 560 mm diameter and 7-blade layout, this Dorman cooling fan blade supports proper airflow through the radiator and engine bay. The black steel finish provides a clean OE-style appearance, and the standard replacement construction makes it a practical choice for Dodge Ram 2500 cooling fan blade replacement and Dodge Ram 3500 engine cooling fan service.

What It Helps Address

• Cracked or damaged original cooling fan blades
• Excessive blade flexing during operation
• Reduced airflow through the radiator
• Cooling system noise caused by a worn fan blade
• Need for a direct-fit replacement on Dodge Ram 2500, Ram 3500, and select D-series trucks

Confirm blade diameter and mounting style match the original fan assembly, and inspect the clutch fan components, shroud, and surrounding cooling system parts for wear before reassembly. Part number 620-066 is intended for direct replacement use on the listed applications.
