Help for a freind

A freind of mine is going to help one of his freinds replace the motor for the radiator's cooling fan. However, he doesnt know where to start. Anybody have any information they can share?
Thanks,

I was gonna try to replace my radiator fan motor, but couldnt find one without buying the whole stinkin assembly from ford for 350$.. I bought an aftermarket fan and had overheating problems... just go to a junkyard and get a used radiator fan for like 30 bucks and bolt it on, otherwise you will have to buy the new motor, drill thru the rivets, take apart everything.... so not worth it.
