How to Replace a Radiator Fan

    Electric Fans

    • 1). Park your car in a safe place and open the hood.

    • 2). Unplug the radiator fan electrical connector. Follow the electrical wires coming out from the center back of the electric fan to its wire connector. Press the lock tab and pull the electrical connector.

    • 3). Remove the radiator fan and shroud assembly from the vehicle. Remove the fan shroud mounting bolts using a wrench or ratchet and socket. Most shrouds have just two or more bolts on top of the assembly. The bottom may have mounting dowels that fall into rubber fittings. Still, other models may use mounting brackets. If there are no mounting bolts at the bottom, lift the shroud and fan assembly straight up to remove it from the vehicle.

    • 4). Remove the old fan and motor assembly from the shroud and install the new fan in place. Install the shroud and fan assembly in place, making sure the bottom dowels slide right into their fittings. Install the mounting screws and plug the fan electrical connector.

    Driven Belt Fans

    • 1). Park your vehicle in a safe place and open the hood.

    • 2). Remove the radiator fan shroud if necessary. Using a wrench or ratchet and socket, remove the shroud mounting bolts and remove it from the vehicle or slide it back over the fan.

    • 3). Remove the radiator fan mounting bolts. On some models, you will be able to remove the fan mounting bolts using a wrench or ratchet and socket. On other models, you might have to remove the fan clutch and fan assembly off the vehicle to replace the fan.

    • 4). Set the fan on the clutch assembly and tighten the bolts; then set the fan assembly in place and start the mounting bolts by hand first; then tighten the bolts in a crisscross pattern. If you only remove the fan, set it in place; then install and tighten the mounting bolts in a crisscross pattern. Set the fan shroud in place and tighten the mounting bolts.
