Car Overheating. Any ideas why?
As the title says, my car seems to overheat, and I can't find the source. I replaced the radiator with a new Mishimoto aluminum radiator, put in a brand new thermostat and gasket, and made sure there was enough coolant. The other day, was driving and heard a loud whining sound coming from the car. Got home a minute later and saw coolant all over the engine bay. Coolant reservoir tank was full, radiator was losing coolant. Any ideas what could be causing the overheating?

1: Any white/ blue smoke coming from your exhaust pipe?
2: Was the car correctly "burped" (getting all of the air bubbles out of the cooling system) when the car was refilled with coolant?
3: Do you see any black soot around your engine bay? Via valve covers, crankcase ventilation system areas, pcv valve, or even in your actual exhaust pipe?

Not sure about the white/blue smoke, but I thnk there might be. I have an open downpipe until the weekend so I can't really tell. Car was correctly burped. Cycled it a few times through, about 15 minutes to make sure I got all the air bubbles out of the cooling system.
As far as black soot around the engine bay, I have not seen or felt anything. I've been working on it installing the new radiator and didn't see anything out of the ordinary.

The same exact thing happened to me after a coolant flush. The first time I filled the cooling system with fluids and thought I got all the air out, but took it for a drive and it puked coolant everywhere.
In the end, I spent at least 25min checking and filling the cooling system with fluid and it was fixed. Apparently Subaru cooling systems trap a lot of air if not done the proper way.

I hope you find the solution before its too late.. Overheating can lead to blown head gaskets

And yeah, I heard the engine can completely seize rendering it useless so I want to avoid that at all costs. I can't afford a new engine or car at the moment. Thanks for the input guys. I'll see if this fixes the issue.

you can also try doing it on some ramps or on a slight hill. you want the front radiator cap to be at the highest point. engine takes a while to suck the coolant from overflow tank back in. I did it a few times, until I didn't need to fill it anymore. after driving it around for a day or two, filled overflow tank and radiator again (a few ounces) and the level never went down since. honestly, it sounds like there is still air in there with possible leak somewhere (cap, hoses, maybe even crack in radiator)
