Pusher/Puller Fan

[jazzyjay]

I was wonder is there a difference in putting the fan in front of the radiator as oppose to behind (factory location). The is a lot of room in between the intercooler and the radiator.

Well first off it wont work if you just take the factory one off the back of the rad and put it on the front. The fan will still be turning in the same direction as it normally would (pulls air across the rad normally) so by mounting it between the rad & ic its going to still pull the air, which is obviously is moving the air the wrong way. Their DC so you should be able to just swap negative & positive wires to get it to run in reverse, forcing air across the rad but it probably still wont work that well as the blades weren't designed to work that way. With the aftermarket fans that can be pusher or puller you have to flip the blades depending on which way you want to use it.

I have aftermarket fans, to switch them it is a matter of switching the wires. What I want to know is it going to be the same amout of air passing through the radiator

It should be the same or close enough that it wouldn't make any difference.

Yes, it's the same amount of air.

They have two settings, regardless of positioning. Stop and Go.

Thanks!! I wonder why more people don't do it it frees up alot of room between radiator and turbo

I know on 2G's if you still have AC I don't think there is enough room between the rad and AC condensor.

 

[jazzyjay]

No AC

as daren stated, you can't just reverse wires and expect a puller fan to become a pusher, you need to flip the fan blades too.
