Fan Motor

The radiators cooling fan service requires you to begin with removal of the No.1 cooling fan after draining engine coolant and disconnecting upper radiator hose along with cooling fan connector and ECT switch connector. Detach the cooling fan from the radiator by removing its two bolts and disconnect the ECT switch wire holder and connector from the fan shroud before removing the cooling fan. Detach the cooling fan connector then remove the two bolts which allow the No.2 cooling fan to exit. The disassembly starts with unfastening the fan and nut before moving to the No.2 cooling fan where the two screws release the motor cover followed by disconnection of wire and connector holder from the fan shroud then removal of the three screws to extract the fan motor. To reinstall replace the fan motor first using three screws before putting the wire and connector holder on the fan shroud followed by setting the motor cover with two screws and finally attaching the fan with its nut. To install the No.1 cooling fan begin by mounting its lower side on the radiator bracket and tightening two bolts to 5.0 Nm torque while also installing the wire and connector holder on the fan shroud, connecting the fan and ECT switch connectors and reattaching the upper radiator hose followed by filling with engine coolant and starting the engine to search for leakage. Position the lower section of the No.2 cooling fan onto the radiator bracket before fastening both bolts with Torque: 5.0 Nm while connecting the fan connector.

The procedure for radiator cooling fan motor repair starts with No.1 cooling fan removal after disconnecting three relays and releasing three connectors and securing the two holding bolts at 5.0 Nm (50 kgf.cm, 44 inch lbs. torque). The service protocol calls for draining engine coolant before progressing to separate the No.2 cooling fan and disconnect the upper radiator hose from the radiator along with cooling fan connector removal and 3 bolts securing the cooling fan with a torque of 5.0 Nm (50 kgf.cm, 44 inch lbs.). Disassembly of the TMC Made No.1 cooling fan begins with untightening a nut and removing the fan followed by lead wire disconnection from the fan shroud and 3 screw removal of the fan motor. The disassembly of TREK Made No.1 cooling fan starts with fan clip removal and access to the fan component while avoiding motor shaft damage and preventing scratches. This allows access to the fan motor and lead wire disconnect from the fan shroud and three mounting screw removal. The TMC Made No.2 cooling fan demands the same steps of nut and fan removal followed by disconnecting the lead wire from the fan shroud along with removal of the 3 screws and fan motor. When handling the TUSK Made No.2 cooling fan also separate the clip and fan while taking care to protect the motor shaft and disconnect that lead wire from the fan shroud followed by removal of the 3 screws and fan motor. The reassembly follows the same process in reverse order as was used for disassembly but in the opposite direction.

Remove the 2 bolts to disconnect the cooling fan from the radiator, followed by disconnecting the connector holder and wire for the ECT switch from the fan shroud before removing the cooling fan.
