How far should the e-fans be from the radiator. the previous setup I had was right up against the radiator. I had heard somewhere that it had to have some clearance between the two.

 

it should bolt right up to it, that way it can pull the air straight off the radiator.

 

You just don't want any possibility of the fans rubbing against the radiator.

 

thats how i had it and a so called performance expert in town said it had so be about half an inch away from the radiator. thanks for the help. later

 

I built prototype units for GM. Directly to the radiator! As said earlier, if there is a gap between the edge of the shroud and the core it will suck air through the gap instead of the core. An example of how important this is is to look at the space between the a/c condenser and the radiator, GM seals that with foam so air HAS to go through both cores.

 

The GM setup on the 06's is bolted directly to the radiator. That is by far the best way to go!

 

i have a question and i dont mean to hijack and i kno i sound like a newb but could someone be so kind as to tell me y efans r better than stock or w/e?

 

E-Fans help the engine stay cooler more efficiently and add hp/tq

 

yeah, what he said

 

It's not how far the fan is from the radiator, It's how well the fan sucks air thru the shroud. Unless your putting it on the front and pushing air through the radiator. If your pulling, as long as your shroud covers 75+% of the radiator and your fan is at the mouth of the shroud, distance doesn't matter!!!! The shroud is the key.. I cooled a Kick *** 327 in a s10 with a single core radiator just because the fan and shroud where correct.. Hope this answers your question...
