hey i wonder if people can help.im getting a grs full length intercooler for my frst and going to mount the fan(poss 2x10 inch ones) to the radiator.im wondering should it blow through the radiator or draw it out?

 

I Didn't read the question properly.

Would be better if you could get them on the engine side

 

Id of thought they would need to flow air in the opposite direction to the car going forwards
other wise thed be fighting the natural air flow and could possible cancel out any airflow through the rad whilst the car is moving
does the rad sit behind the intercooler?

 

sucking is more efficient.

 

yeah will do.radiator,fans then intercooler on the outside.no room to fit fans engine side.still non the wiser.anyone else?

 

blow if there in front of the radiator, and suck if there behind it on the engine side, its common sense mate if you think about it

 

yeah i know that fella but was just curious thats all.i was just asking as i see some people put the fans in front of the intercooler aswell so double checking putting them on the rad would be ok

 

Correct.

But of more importance is ensuring the fan actually draws or blows air through as much of the core as possible.

That means either enough fan area to ensure good coverage, or proper shrouds/cowlings as the OEM do.

Regardless of how you do it, make sure it is flowing COLD air from outside through the rad into the engine bay, its really annoying how many cars we get in here with it wired backwards so the radiator fan sucks hot air from the engine bay into the rad to "cool it down"

 

fail! Lol
Something I've never thought about, but in my mind would be the first thing you check after you wire a new fan up lol
