The one you want is Taurus Fan 3.8L... 4500CFM airflow, 3-wire hookup, 2-speeds (high/low). Dimensions are 17" Tall, 22" Wide, & 5" Deep. This thing will cool anything. I had one on a Jeep with a 350TPI I ran in the woods. Never a problem. 1985 (I think) -1995 Models. As far as controling it with no problem try this
