Electric or mech fan?
Putting a puller onto the rad is like turning a 28" radiator into a 18" circle core. you want some stand off and a full shroud so it will pull across the entire rad, not just a pizza sized circle. The popular Ford 'Contour' fan assembly has 2 12" fans mounted in a diagonal and a full shroud so the fans pull across 100% of the radiator (or whatever is inside the shroud). Put a 50A fuse inline as these draw a buttload when they kick in. you can use a Hayden temp control available where you find Hayden products, ie. Pep Boys. I think #1 is primary and #2 is secondary. Fox body guys been using these for years.
