Koyo with 210F
I have a koyo rad and ast by pass, but I'm getting 210 and up during a hot day. Is it normal for this setting? i thought it should be quite abit lower than the stock due to most twice as big as the stock. the temp is not much different with my stock rad before, any thoughts??

I saw your post, and you have like 230C and higher, that's a bit scarey. I think my max temp is just slightly highter than 210C, nothing higher than that for now. I just want to know what's the normal temp for a koyo compare to the stock?

I dont see how an aftermarket radiator can cool better than a stock raciator if you are using the same bumper as before. I replaced my stock with a koyo about 1.5 years ago. No difference in temps.
FYI, it was about 100 on saturday and I hit 100 on the highway. I cant use the a/c and its down right scarry. On a cool day like today never went above 85.
Life sucks get used to it.

Do it right, do it once

The reason the temps aren't any different in traffic because you have the same fans pulling the same air or slightly less due to the thickness of the Koyo.
You should notice a difference if your on the track, otherwise the stock one isn't as bad as people think.
FDs run the coolest on the freeway, if your having troubles with the AC and temps on the freeway your T-stat is bad and/or your AC condensor is plugged up with crap.
I have seen T-stats go bad in as little as 1 month.

yeah, what turbo jeff said.
Your t-stat is gonna control the temp by controlling the coolant flow through the rad. Its just that under the right conditions (hot, traffic, track, ect.) the stock rad can't extract enough heat even with the t-sata all the way open.
or something like that.....

I run the stock radiator and my temps have never got over 95C which is 203F even sitting in traffic on a 100 degree day in the middle of the afternoon.
I dont think your going to see a real difference in temp with a aftermarket rad. The only reason to get a aftermarket rad is cause the end tanks on the stocker suck and are prone to crack overtime.

However, I do agree that normal driving won't really show the benefit of an aftermarket radiator (unless the stock one is all beat/clogged up and the fins are blocking air).

I don't have a temp gauge yet but i'm going to replace the stock radiator, ast, and add a temp gauge. I've read all the old threads I can find about Koyo vs. Fluidyne.
My findings. Koyo more cooling capacity harder to install. Fluidyne better fit cooling capacity not much more than stock. Both are quality products. I'm leaning towards Koyo.
Did I get that right? I'm going to do some track and autocross, but car is fairly stock. Any input.... turbojeff??

fart on a friends head!!!
if youre stuck on changing out the stock radiator, then go with the one you feel is worth installing. neither of the stock replacements are gonna make cooling issues better. youre just as good if you find a stock replacement with copper or aluminum or metal. . . whatever endtanks. its cheaper that way.
i see lower intake temps when i get off the interstate. i do generally 80mph on the interstate and when i drop to about 50-60mph i see around a 3-4 deg drop in water temps. kinda weird if you ask me. haha.

Bigger radiatiors help cool the car when it is moving becasue the radiators work on a ram air basis. They need air flowing through the front end to help keep them cool.

true, but you need to have an efficient system for that to work correctly. the stock setup is not the most efficient way to keep the water cool. . .

I would agree if you had a larger openingin the bumper.

With the decrease in speed the RPMs decrease. The engine is then not working as hard. So the engine puts off less heat. And 50 MPH wind is still faster then the fans can pull it in. That is why you see lower temps at those speeds.

I see some of my cooler temps in traffic and sitting. Yes the engine will slowly rise in temp but as soon as my fans kick on (98-99c) things drop right back down to 90-92c. It will stay there if I stay off the boost. Once I add boost and RPM I see temps will into the 105 c range. I am a little worried about those temps if the go a touch higher. Although I have seen oin the other post (Hot Summer Days/Hot Temps) that some people get up into the 230 F range (which is I think close to 110 C).

don't race, don't need to
Not that it matters, but what I noticed between stock and Fluidyne was NOT a difference in overall temp in a given situation, but rather how quickly the Fluidyne was able to remove heat from the cooling system versus the stock, in that the temp came down visably faster with the aluminum radiator. This is with everything in the stock layout...
