How To Replace A Radiator Cooling Fan Motor

There can be a number of reasons why your car is suddenly overheating. One of the main reasons is that the radiator cooling fan has stopped working properly or at all. The first thing you should do when a fan stops is to check the fuse to make sure it is not blown. The other thing you can do is check the electrical connections along the power cable that runs from the fan's motor to the car's engine to make sure none of the connections have come loose.

If everything is okay, the next thing you can do is replace the cooling fan motor. Here is how you can replace the radiator cooling fan on a typical car:

You Will Need:

  • New Cooling Fan
  • Crescent Wrench
  • Philips Screwdriver

Safety First

Make sure the engine and radiator has cooled down before you start to work on replacing the radiator cooling fan so you don't get burned. You will also need to disconnect the power cable running from the car's engine to the fan's motor - all you have to do is follow the cable until you reach the clip connecting the power cable to the fan and pull the clip out of the fan's motor.

Remove Old Fan

The fan's housing is located between the engine and the radiator. The housing in held in place by a bolt in each of its four corners – you can remove the bolts with a crescent wrench. You may also have to remove any hoses, wires, or any other obstructions that might interfere with pulling the fan housing unit out of your engine compartment (make sure you note what goes where if you have to disconnect any other parts to get the fan out).

Put in New Fan

Remove the fan blade from the shaft holding it to the motor – this is typically held in place by a screw or a pin. Flip the housing unit over and remove the screws holding the motor to the unit. Slide the motor out and put the new one in its place. Reattach the screws and the fan blade. Take the housing unit and bolt it back into position in the car and reconnect the power cable to the fan's motor.

Make sure you reconnect any hoses or electrical wires you might have had to move to get the housing unit out of the car. Start the car and turn on the air conditioner (using the air conditioner makes the car heat up faster) and wait until the engine gets hot. You know you are done when the fan kicks on to cool the engine down once it heats up.
