i was wondering if there is a way to remove the motor from my electrical fan with out having to take off the whole fan assembly from the radiator? cause my fan quite worken on me and ive checked the fuses, wires and the sensor on the manifold that controls when the fan comes on and off.(everything was fine) so im led to believe that the motor is the only thing that could be causing the fan not to work.

 

There are 3 screws that attach the fan blade to the motor and they are facing the radiator. More than likely you will not be able to remove them w/o removing the whole fan assembly. Also a nut that attaches the blade to the motor. I don't know what kind of car you have but they're not that hard to remove. Probably a lot easier than trying to take the shortcut. My advice is take the fan off, much easier/safer for the radiator.
Hope this helps...
