I need to upgrade my radiator cooling fan since I have a b16 and my A/C fan had to be pulled out for the header clearance. Now the Radiator fan is pulling double duty as both radiator fan and A/C fan.

I have A/C and live in Phx. It's 106 degrees out as I write this. When I'm sitting I overheat. With my windows down, I melt.

I figure if I double the CFM of the stock fan, it should offset the lack of the A/C fan.

How big of a fan should I use? <U>What's the CFM pulled by the stock radiator fan?</U>

Anybody w/ a B16 please help!

 

why dont u get a smaller ac fan? my friend with a b16 got some tiny ac fan and mounted it on the other side of the radiator. ill let him know

 

get a small pusher ac fan and put it on the opposite side of the radiator, wire it into the ac fan connector,

 

To get the same cooling that a pull fan provides, a push fan needs to be at least 1/3 stronger than the pull fan it's replacing.

There's also not much clearance on the front side of the radiator. Anybody got an idea what size fan I could fit on the front of the radiator in front of the header side?

 

put in a 180 thermostat and get the relay so the fan comes on at a lower temp and it will never get hot. i wired my fan straight to the dizzy so its on all the time, yes i know its ghetto.

This is what i would like to know as well.

 

This is what I did, its better than nothing.

Bought a spal fan from EBAY. (http://www.spalusa.com/) The 7.5 inch fan,
only 2.05inch in thickness.

Or get a push fan like someone said and mount in front of radiator / condensor.

Works good!

BUMP. I need to know how much CFM I have so I know what fan to get.

 

BUMP.

 

i know its not pulling any more than 1500cfm, so just get one that is even better for sure.

Do you know what the amp draw of the standard fan is? I don't want to blow fuses back and forth.

BUMP it up.
I need to know what the standard radiator amp draw is. I know the AC condensor fan runs on a 15A fuse, I don't know which fuse is for the radiator fan.

Please help me out guys. It's about 105 degrees out right now.

 

I have a B16 installed in my CRX also w/AC connected. I bought a new bigger radiator and installed a 12" slim line puller fan and then in front I installed a 10" pusher fan (w/a few bending of pieces it fits). Both fans I got at summit and used the plugs already there from stock fans w/no power issues at all and no overheating problem at all. Thfans cost about $60-70 nad I got an aluminum KOYO 3" radiator at absoluteradiator.com for $300ish. Maybe pricey but I do not want to ruin my engine and I am now enjoying AC with NO PROBLEMS!!!!!!!!!

 

I'm assuming you're using hasport billets? I ran all their stuff w/the a/c and all for a long while w/my stock manifold and it all fit. The ratiator is a stock sized full metal one from 1-800-radiators.com or somethin like that.

But when I say it fit that meant the manifold cover touched the a/c fan, but it didn't cause any problems. No pic, but you get the idea.

But then again, I'm only in GA where its in the 90's. It's h t
