So I just got my wife an 04 excursion and I inherited her 99 F250 Super Duty. I recently rebuilt the a/c system (new compressor, condenser, evaporator, dryer, and orfice tube.) so I know its running correctly. The problem Im having is the a/c doesnt cool as well as it should when im in my usual stop and go traffic. In south Louisiana it gets hot, and people love to hit their brakes. So now im thinking about adding a pusher fan in front of the radiator that comes on when the a/c comes on. Im thinking that will help my slow speed a/c. At highway speed, the a/c will freeze you out. Question is, have any of you guys done this or know someone that has? Do you guys see how it would cause a problem? I was told the fan motor would cause a restriction at highway speeds but I dont know how much it would hurt. I need some brainstorming to go on here, the Ford truck forums seem to be closed minded to new ideas.
