Default Are stock Civic radiator fans pusher or puller fans?

Please let me know the answer to this question. Because I may have found the answer to why my CRX is overheating since I put the EG radiator into my car... Maybe I wired it wrong?

Topic:

How are stock Honda fans designed to be run?

Here is why I ask:

When I pulled the stock radiator fan, and I put in the EG radiator (using the EG's fan), I wired the fan as it was on my stock CRX fan harness, blue for blue, and black for black (matching the black and blue wires on the EG radiator with my CRX's black/blue fan harness...)

I noticed that the fan pushes forward when parked. I got to thinking that perhaps it's supposed to pull air. Is this correct? Because if that's the case, then I have wired it wrong, and that would explain why when I am driving, my car would get hot, and not cool down until I come to a stop. Come to think about it, that is when things started to get hot, is when I put that radiator in.

It's when I am driving that it gets hot, therefore making the air shooting into my radiator, become hot because the fan is blowing the opposite direction.

What does everything think? How are these fans designed to be run? Push forward through the radiator? Or pull air into the engine bay? It would just seem weird that it is designed to push forward if the air is being shoved in the opposite direction when driving...

Please let me know if this is my issue?

Just a quick answer to your fan question, it pulls air into the engine bay. It draws cooler ambient air through the rad.

Yes your fan is blowing in the wrong direction it should PULL air in from the outside thro the radiator or thro depending on where it is. Basicly outside air should pass thro it from the front of the car towards the motor.

Not, not turn it around, but wire it up right. I thought blue/blue, and black/black. Guess I was wrong...

Anyone else think that blue/blue and black/black isn't right on it (which is pushing)?

That I should have wired it blue/black and blue/black to pull air instead of like I have it?
