• Q: How to replace the Radiator Cooling Fan Motor on 2005 Toyota Prius?

  A: You should start your Radiator Cooling Fan Motor FAN (1NZ-FXE) replacement by taking off the listed components starting with REAR FLOOR BOARD NO.2 then DECK FLOOR BOX REAR and ending with REAR FLOOR BOARD NO.3. The first procedure is to disconnect the BATTERY NEGATIVE TERMINAL before removing the RADIATOR SUPPORT OPENING COVER and ENGINE UNDER COVER LH along with ENGINE UNDER COVER RH. Engine coolant must be drained by starting with the engine side radiator coolant removal followed by the removal of the drain cock plug then completing the drainage from the hybrid side radiator. The FRONT BUMPER COVER and FAN ASSEMBLY W/MOTOR require their connectors and hoses to be disconnected with clamps removed before technicians can unfasten inverter and cooler brackets and hood lock assembly and radiator support. Secure the new fan using two nuts before putting back the FAN ASSEMBLY W/MOTOR with four bolts by torqueing them at 7.5 Nm (76 kgf-cm, 66 inch lbs.). Put radiator support into place by fastening 5 bolts to 5.0 Nm (51 kgf-cm, 44 inch lbs.) and reinstall hood lock assembly and horn connector. Install the cooling unit brackets by applying the required bolt torque metrics. Service technicians should reconnect the BATTERY NEGATIVE TERMINAL to the vehicle while tightening it up to 6.0 Nm (61 kgf-cm, 53 inch lbs.). The REAR FLOOR BOARD NO.3, DECK FLOOR BOX REAR, and REAR FLOOR BOARD NO.2 should be reinstalled before filling both radiator sides with ENGINE COOLANT. The system concludes with a check for coolant leaks conducted on the hybrid and engine sections followed by installation of the ENGINE UNDER COVER RH and LH components and RADIATOR SUPPORT OPENING COVER. Lastly, initialize the POWER WINDOW CONTROL SYSTEM.
