If, as you say, you're using the electric in conjunction with your stock fan, you are probably going to be forced to make it a pusher (front mounted). I don't see where you'd have the room to mount it behind your radiator because of the stock fan and shroud. If it is a universal electric fan, you should have no problem. But some fans were designed as pushers only or pullers only. And if you have air conditioning, you run into the problem of the condenser mounted most likely on the front of the radiator. I don't mean to say it's not a good idea, because it is. If you get it mounted, just hook it up to a 12v switch and pop it on when you get into stop and go traffic. Slick!
