Default Thermostat and Rad Adventure

Hey folks,

So my Outback XT (2005) was overheating.

So I got a new Tstat today, and I took both of them and boiled them from cold. When looking in the water, they are very close, but when taking them both out and standing them up on the counter, one closes far sooner than the other. Success!

But then, upon installing the new Tstat, I filled up the rad, and saw water flowing out from somewhere. I assumed the fins had uncrimped from the initial rise over normal operating temp, and using compressed air I saw it was coming from the top hose area.

So I pulled off the hose.

And the flange came with it.

It seems the flange had rotted away inside the pipe, and now I need a new radiator :/

I was thinking aftermarket, because the dealer is going to **** me on this anyway, and found this:

http://www.rallysportdirect.com/Koyo...acing-Radiator. Spec says it fits a Legacy GT, which is the same engine and body as my Outback XT, but I'm a bit worried it won't fit.

Will this fit?

Am I better off just going with an OEM unit?

You don't need anything so extreme. It should fit though.
I have a Silla radiator in 2 of my SVX and they are excellent quality and fit. Very inexpensive too. $115.00 shipped.

I think a mishimoto is about $100 cheaper than the one you linked. Seems like I've read of people being happy with those.

I was looking into a new Radiator and Koyo makes a perfect replacement and price is about 115. The one you were looking at is all Aluminum and really designed for racing applications and just street driving would be a little to much.

I'm using an OEM Subaru Tstat.

I'm just trying to find out if the rad needs an integrated ATF cooler, mostly.
