Default stock radiator = crap?

So the car has been great to me lately. Haven't really done anything at all to it for a few months now. Its just been a sweetheart. No issues, no hiccups, nothing.

Today I decided to take a little drive in it. Just a casual 20-30 minute drive for no reason. I gave it a little WOT here and there (nothing major, very quick bursts) and the car is just absolutely amazing.(lit em up in 2nd and a little in 3rd)

I get home, everything is fine, when I notice a little steam coming from under the hood
Pop the hood and radiator is dumping coolant all over the place, and I can't see where its coming from.

Shut car off, took off rad brackets, took off driver side fan, and looks like its leaking from where the stock plastic end tank is connected to the aluminum radiator portion.



Guess I'll be looking for a new radiator.


Is this normal? Car has 60k and this is original radiator. Car has a coolant re-route and temps are always great. Doesn't get tracked, and very rarely driven hard. Is the stocker just a POS?

Just wanted to check before I get all paranoid and start going through everything to make sure nothing else is causing this. (hope not cause just about everything is new/near new under the hood)

My aluminum radiator was one of the first things I bought for the car. **** the junk plastic ones.

You can find one for a pretty good price now if you look around. Back when I got mine I was FM catalog happy and spent $450ish on my Rod Millen one.

Radiatorbarn.com is where I bought an all-metal twin row stock replacement.
If you don't plan on tracking the car you'd be perfectly fine with a stock-sized one.
Mike didn't even have problems at 400whp+ on a stock radiator on the street.

I'd get an oversized one but I have absolutely no need for it.
With the re-route my car runs cool as hell, and I don't track it, so it would be pointless.

**** me, for $62 shipped I might order one just to have it. I'm still running the stock plastic rad.

The CX racing ones are at least 2", much bigger than stock.

Make sure you duct every last bit of air through it and between the fan shroud and radiator too.

Sucks that they offer an all-metal two row one for NAs, but only the stock style for NBs (you can go to the "racing" style but that is a lot more expensive).

No need for racing style. Car is never even pushed hard enough for long enough to need any extra cooling.

I do plan on shrowding everything down there before summer comes though.
Its fine now, but when its 100+* outside I might need the more efficient airflow to my heat exchangers.
