This is what I did.Even after putting in a Griffin aluminum radiator I had problems when idling.I looked over the Spal catalog and found a very thin 16" pusher. I mounted that in front of the radiator behind the grill. I bought the wiring kit and mounted the relay under the battery tray. I wired an under dash mounted switch and I turn it on when I need to. I don't worry about accidentaly leaving it on because you can hear it.I tried it without the engine mounted fan and that didn't work well. Some folks recommend a HHR fan. My buddy just bought one for his Duster and couldn't make it fit. These are street cars not race cars and he didn't want to cut the car up. This has worked for me for 5 years.I was just in a parade for an hour idling and it held it below 200.
