What's a good pusher fan model number that will fit nicely in a stock set-up?

Today my single 16" worked just like it should. I've replaced parts along the way. but there's that trust facto, and with the summer up ahead I want to add a back-up pusher fan.

 

Would have to be pretty thin to fit between the x-brace
and the A/C condenser-i think a thin type 12" flex-a-
lite would fit if the shroud was trimmed just a bit.
The problem with pusher fans is they are about 40
percent less effective than the exact same fan properly
mounted behind the radiator/condenser,the reason is
the air on the discharge side of a propeller fan is
rotating like a vortex and the air hits the radiator fins
at an angle,reducing airflow. if overheating is experienced when the weather gets hot,a higher power
puller fan would be better-HD fiero/buick grand nat.
type,ford taurus 2spd,or '87 up 3rd gen dual fan with
both fans wired to come on at the same time.

 

ok, good thoughts

 

Also, generally not advised to mount a pusher directly in front of a puller, as they will offset eachother and compound the situation. Blowing air into a fan that's already pulling air doesn't really work. If you want reassurance, just get a puller with a higher CFM rating.
