Definitely a puller. Placed at the TOP of the radiator (heat rises) for best cooling.

I put a 16 inch electric fan on my rad w/350 sbc; headers; mild cam; Edelbrock 4bbl carb ... ran double relays and a fusible link (NOT a circuit breaker) ... and my voltage gauge is very happy; she stays nice and cool, too.
