Product Details

Radiator Fan by Dorman®. When you’re driving at speed, there’s plenty of airflow through the radiator to keep your engine cool. But at idle and during stop-and-go traffic, a properly functioning cooling fan is critical for providing airflow through the radiator to transfer engine heat from the coolant to the air. But if the fan fails to come on, your engine could suffer severe damage in a very short time. You can ensure you always have cooling fan operation when it’s needed and save time and money on repairs with this Dorman Radiator Fan. It comes complete with motor, shroud, and fan blade.


  • Comes complete with cooling fan motor, fan shroud and fan blade
  • Engineered to provide optimal airflow to prevent engine overheating
  • Direct replacement for perfect fit and function
  • Manufactured with high fiberglass content for greater strength and improved thermal stability
  • Includes plug-and-play jumper harnesses where applicable
  • Fan motors are fully tested to ensure quality and durability
  • Meets or exceeds OEM quality

Electric cooling fans are far more efficient than their mechanical forebears, only running when needed. They can even run and cool the engine when it isn’t running. However, even though electric cooling fans are part of a complex system of coolant sensors, relays, and computer control that has proven to be very reliable, failures can occur, which if not repaired in time can result in severe engine damage from overheating. At the first sign of a dash light and/or elevated gauge reading, the cooling system should be thoroughly inspected, diagnosed and repaired. With an electric cooling fan, not only can the fan motor fail, but the fan blade and shroud can become damaged, which can reduce airflow through the radiator.

If testing proves that the electric cooling fan is at fault, this Dorman radiator fan assembly will ensure there is optimal airflow through the radiator to allow transfer of heat from the coolant to the surrounding air and keep the engine operating within its specified temperature range. Whether the defect is the motor, blade, or shroud, the Dorman assembly is the smart repair because no disassembly of the old unit is necessary, saving you time and labor cost. It’s designed to directly replace the original assembly for easy installation and perfect function, and the shroud, fan blade and electric motor come completely assembled and ready to install. Plug-and-play jumper harnesses are included where applicable. This premium product is constructed with high fiberglass content for increased strength and rigidity, and improved thermal stability, ensuring long service life.

Works But Not A Direct Fit.
Dorman part #620-637. According to Dorman is supposed to be an exact replacement. Same metal thickness, wire gauge, in their words an exact replacement. It looks the same, except for the top mounting holes but doesn't come with rubber mounting grommets and spacers as the original. You can't use the original grommets and spacers without modification, if you leave them out, the mounting bolts areabout3/4" to long and hit the radiator support. They will work if you are experienced All the installation video's on the web show the fan being removed easily, by removing the top mounting bolts and wire harness, then sliding the fan to the passenger side and up and out. But not in my case, had to remove top transmission cooler line and slide the fan to the driver's side to remove the fan, was told by CARiD sales person that the two fans were the same, (driver's/passenger side) they are not. Upon removal of the driver's side fan found it was a Dorman, and was replaced five years ago. Ordered the passenger side fan and it came used/ already installed. supposedly straight from Dorman, as told by CARiD.

Radiator Fan For Ford Flex
This part was a great part, but I had to switch red and black wire around to make the fan run in the correct way. I would order from them again.

Dorman Fan Assembly
Fan frame not as firm and stiff as OEM, fan rattling a bit from frame flexing. Other wise it works good so far. Good value.
