Radiator fan push or pull?

[Danny]

Anyone have any preference to a suck or blow fan unit ?
Ps yes I know there's a joke in there someware.....

You want the cool air going in over the radiator. Most are reversible fans.

Yeah, I think the point is that when the car is moving, cool air comes in through the rad naturally and when the car is stood still, the fan is designed to draw the same cool air from outside and through the rad. So a 'pull' fan I guess.

You say that, but SPAL for example designate 'Pull' and 'Push' on their fan profiles. They're designed for a fitment.
