Possibly as its just an electric motor in most cases I think they're pull fans anyway so behind the rad
 
just bin out and tried 1, wire it 1 way and blows air the fan side and swap wires around and blows air the motor side of the fan! :confused:
 
im a little confused! lol if i wire them so air is pulled though the fan it shouldnt matter if their 1 side or the other side of rad? wot i was asking is wots best for cooling?:confused:
 
It depends entirely :rolleyes: on the fan design. Whether yu push or pull doesn't matter. Theoretically pulling air through us better, but lots of manufactures put fans in front of the rad. It is more important to fit the biggest fan possible.
 
1 got 2 at about 12ins so that should be ok just thought it would be better 2 push cold air from outside than pull hot air from engine bay?
 
Yes, it's the actual design - like ships propellers. Reversing the wiring is irrelevant.
Some suck n sum blow

I may have misunderstood your post but you can't pull hot air from the engine bay through the rad'.

You must drive air from front to back (of the vehicle) regardless of whether the fans push or pull they must move air in the right direction, or you could end up fighting the natural air flow caused by the vehicle moving forward and end up with little or no effective flow and an overheated engine.

Exactly. the air has to go from in front of the rad towards the engine.
 
ok the pennys dropped! lol so im either blowing air from outside or sucking air from inside

No you're either sucking air in from outside or you're blowing air in from outside.
