Re: ls motor is overheating!!!
I thought that was how I came to my initial internet mechanic guesstimation. But since I actually respect your opinion on these types of matters I'll choose to take that as a compliment regardless of your intent.

Re: ls motor is overheating!!!
Another thing you could check...
I had my radiator on the STi go out last weekend. It took me a while to figure out where it was leaking. I would pop the hood and coolant was all over the front of my engine, but I couldn't see a leak. Well for some stupid reason, they have decided to make radiators in a lot of newer cars with plastic end tanks on the top and bottom. The aluminum was separating from the plastic, but ONLY under a lot of pressure. I could idle the car for 30 minutes and wouldn't see a drop come from anywhere. I'd drive a block and smoke would start rolling out of the hood. I didn't actually find exactly where it was until I revved it to 6k a few times, then saw smoke, so I jumped out and ran to the front to find a piss sized stream coming from where the plastic and aluminum meet.
From everything I read on multiple forums, plastic/aluminum radiators seem to always go in this fashion anywhere from Dec-Mar (I noticed this about EVERY post I read about the subject). It's possible yours could be leaking from the bottom of the end tank and not spraying onto something, making it hard to find.
Might not be what's causing your issue, but just some food for thought. I'm actually about to install my new radiator right now, sat at work waiting for FedEx for the last 5 hours waiting on it, lol.

By the way, the Koyo OEM replacements for the Impreza fit perfectly if you're wondering, except for the extra thickness and the hose trimming. Excellent upgrade though.
What a completely shit OEM radiator design. My Subaru can handle anything, except properly cooling the engine in the winter without splitting a radiator end tank...
GM radiators are notorious for splitting their plastic end tanks also, as are many other makes/models.
