Electric - Pusher Fan ?

This is probly true, but there are those that have a hi h.p. engines that makes more heat than a stocker. Band aids may be necessary----- Over 700 horses is harder to cool than 3-400.
I had a 15" pusher in front to help at stop lights, and pulled it out in experimentation, haven`t noticed much diff. , except no extra cooling at the stop lights. Was comforting to hear it kick on when over 200---

Then you should ditch the mechanical fan system altogether and go full electric with fans that move enough cfm. Having both is just a waste of horsepower and efficiency. Just because it “works” on your car doesn’t mean it’s the best way to do it.

Regardless, the OP is talking about a mostly stock 318, so all of that is irrelevant.
