Dorman 621-548 Radiator Fan Assembly Without Controller

The Dorman 621-548 is a direct-fit replacement radiator fan assembly designed for select Honda Civic and Acura ILX models. This engine cooling fan assembly is engineered to restore proper cooling system function and prevent the engine overheating issues that result from a failed or underperforming radiator fan.

Dorman engineers this assembly to match OEM fit, form, and function — no modifications required. The fan motor is tested in laboratory settings to confirm it meets the performance standards of the original equipment part, so you can trust it will cool as effectively as the factory unit it replaces.

Key Features:

• Direct OEM Replacement: Precision-engineered to match the fit and performance of the original stock radiator fan assembly
• Complete Assembly: Includes all components designed with the same materials as the original part — ready to install out of the box
• Motor Tested: Fan motors are laboratory-tested to verify performance before leaving the factory
• No Controller Included: This assembly does not include an integrated fan controller — ideal for applications where the controller is reused or sourced separately
• Cost-Effective Alternative: Delivers reliable OEM-level performance at a significant savings over dealership pricing
• OE Cross-Reference: Replaces Honda OEM part numbers including 19015R1AA01, 19015R1AA02, 19020R1AA01, 19030R1AA01, and 19030R1AA02

Replacing a faulty radiator fan promptly is critical — a non-functioning cooling fan can lead to engine overheating and severe drivetrain damage. The Dorman 621-548 makes that repair straightforward with a bolt-in assembly that restores factory-level cooling performance.
