For what it's worth, it is a bad idea to run both a pusher and and a puller fan. The pusher air flow wise degrades the ability of the puller fan to pull.

It doesn`t on mine, I have it mounted as far from the radiator as possible, on the pass side of the rad, set to come on at 200, comes on when the termp outside is in the 90`s . When in the driveway ideling, w/ the hood off, u can feel the extra air it pushes , helping the mech. belt driven fan. 505" wedge-aprox. 700 h.p. in a 68 fastback. I also have an aux. trans cooler on the drivers side, mounted the same way. 28x19 , 1 1/4 tube crossflow alum. rad.
