Better cooling fans/radiator?
Has anyone installed better radiator fans or a better radiator to compensate for the intercooler? I keep heating up too much at a stop light and then it cools back down as soon as I drive... the stock fans just don't pull enough air through the intercooler/ac/radiator to keep it as cool as stock. If you put your hand behind the fan on mine vs. my friend's stock Civic you can tell a lot less air is coming through, so that's definately the problem.
I know Dezod sells a Koyo radiator and FAL has fans that will fit our car that push 3x or 4x the air that the stock units do, just wanted to get some opinions from anyone with a turbo and intercooler that has had to do this upgrade.

C2i0v0i1C had a radiator installed, but i can't remember which one. I know his shop had to make custom brackets. It might have been a fluidyne but not sure. PM him.......he isn't on too much anymore, but he will get it soon.

Rep Power: 0 I've seen fluidyne radiators on older model civics that only take up half the space. I was wondering if one of those would fit and still be efficient in keeping things cool.
I'll look into later but i dont think anyone or many of us at that have gotten to your level where we might need one. You I think you still have the most money invested in your kit...MAdwheel should be close:

It's the same symptoms as fans not working because they can not move enough air through the additional restriction of the intercooler to the radiator.
Speedracer32- The half size fluidyne radiator would probably not be enough, a lot of the 5th gen civic guys have to upgrade to full across radiators when they go turbo. Would be nice for engine bay space though.

Rep Power: 0 If you removed your a/c condensor, you may not have as much problem as me, since that's one less restriction. Mine only does it on days over 92 or so degrees, but right now, that's constant here.

Rep Power: 0 Is it only hotter after you've been in boost for a little while (as in getting on the freeway) or from just regularly driving it on the freeway, cruising along?
If it is warmer after just cruising normally out of boost... that may be another problem. At freeway speeds the airflow should be good enough to keep everything cool; maybe you are running low on coolant or have a bad thermostat/thermosensor? Just a few things to check, since that sounds like a different problem than what we're talking about here.
But if it only happens after a run in boost or when you push it hard... yeah, mine does that as well. Everytime I get on the freeway using high boost it gets a little warmer and then cools back down about a minute later while cruising on the highway.

but ne way. dezod sells a radiator for us its very nice and im bout to order one myself. check it out on his website.

Rep Power: 0 The headgasket is not blown, I already checked that theory out, and the car does not have any of the symptoms except overheating at a stop, which is the same symptom as inefficient fans.
I’ve had a car with a blown headgasket, and it ate lots of coolant, blew smoke that smelled really bad, and there was oil in the coolant and vice versa. It also overheated all the time. My car is doing none of this. It only heats up on a hot day at a stoplight, if I drive it that same night when it is cooler, the car does not heat up at all.
Just for you to try… find a friend with a stock Civic like ours and put your hand behind the fans while they are both running and feel the air flow. Then do it on yours. You’ll feel a lot less air come through with your car, and that is what is causing my problems.
Anyways, Dezod: do you carry FAL fans, and if so, do you have an application for an 01 Civic EX?

My friend Josh has a turbo 01 dx and is also currently having the same problem and also blew his headgasket (running 12psi... WITHOUT alcohol
). I -was- turbo, but had too many problems I didn't want to deal with so that is why I am now n/a. btw, I was only running 7-7.5 psi. I think I may have blown it because my alcohol switch failed Thread Starter

Rep Power: 0 Just finished installing two new FAL fans to replace the stock fans, drained and refilled with 1/3 coolant 2/3 water, and the problem has gone away. It's about 97 degrees here right now and I just drove it around for 30 min including a lot of idling, and the temp gauge never moved a bit.
These things move a LOT of air even through the intercooler, a/c condensor, and then radiator... and I'm going to wire up manual switches to both fans just in case I need it at the track.
Doesn't look like I'll need to replace the radiator just yet.

Rep Power: 0 I bought them used from a friend who abandoned a project car he had, so that only set me back $75 total.
I have no idea what they are retail.

Rep Power: 0 I used the 190B FAL fans. They're made for the Ford Focus, but there are a lot of focus guys here and one decided to abandon his project... so they were cheap. Had to trim a little bit of the shroud material but they fit perfectly, used .25" thick 1" wide aluminum I got from the local hardware store for the mounts.
Plus side on these fans, they come with their own temperature sensors and you can select the temperature you want them to activate at, as well as easily wiring in a manual fan switch and connecting the wires for the A/C activation. Or you can use the stock wiring if you want the ECU to control the fans completely.

Rep Power: 0 If you're going to Pepboys for replacement fans, check the CFM rating of the fans. FAL's usually flow quite a bit more air than regular cooling fans and are usually thinner overall than stock style fans.
u know i checked and Compaired My car to my friends 02 ex.... My air , (when the fan is on) not the a/c fan either.... my **** flows just as much... and its TWICE as cold as his stock 02 ex.
maybe u just had defective oem fans, cause even with my FMIC there is no difference on my car-

Rep Power: 0 The OEM fans worked fine, that's the first thing I tested when I started overheating.
How thick is your intercooler, and is it tube-fin or bar-plate? It can make a really big difference in how much air can come through the intercooler.
One thing I never did find out before that may be related to this... do the SF kits have any kind of heat insulation on the downpipe or turbo itself, or a heat shield? Mine has none, and I think that's part of the reason the radiator gets so warm.
