So while thinking about ditching the clutch fan and installing this electric one out of one of donor cars, I realized that these fans can either suck or blow depending on how they are wired.

 

I've never seen one run in the car as factory installation, so I don't know which way they are supposed to go. Suck or blow?

 

As I think about it, seems like if they were wired to suck, then they would be working WITH the air flow as the car was moving forward. If wired to blow, seems like the fan would just be fighting the air being forced through the radiator by the cars forward motion.

 

So hows it supposed to be, or does it matter?

 

But then maybe I think too much.

they suck...

 

pulls the air through the rad....

yes they suck but if you want more room under the hood you can put them in front of the rad, condensor and reverse the polarity

If you put them in front of the radiator, you must not only reverse the polarity but also flip the blade over. It will work if you don't flip the blade, just not very efficiently.

ya if you want more room for wrenching, just flip the wires and recconnect them. i had to do it to make room for the EJ22 i put in my car.

Uh, what fan are you refering to? The 85,86, and 87 fans I'm looking at don't appear to be made in such a way that the blades could be flipped over. They are plastic and cupped to fit over the motor. Or am I missing something?

If you want a blow type fan, I suggest that you go after market. There are many brands that offer slimline style fans that mount in the front of the radiator. I do not recommend flipping the Subaru fan.

The ones that blow are designed to mount on the front of the Radiator. I'ver run into this problem also
