    Unhappy Overheating

    I have an 02 WRX NB-R and it has started overheating. The gauge doesn't really go past half way but when I turn off the engine all hell breaks loose and all the coolant and water comes boiling out. I got the thermostat removed (it was stuck) but that didn't solve said problem. I was told that if it was a head gasket then there would be white smoke form the exhaust. Somebody? Anybody? Help?

    Mine was spewing coolant everywhere because I had a hole in my radiator and I had overfilled my coolant. Maybe something like that?

    Was the coolant coming out of the hole in the radiator? Mine's coming out of the tank beside it (sorry dunno what exactly that tank is called)

    Both. I had a leak in the top corner of the radiator by the coolant holder thing and I had overfilled on the coolant so it coming out of there as well.

    I'll check for a leak in the radiator and I'll also check through the hoses to see if any of them are leaking.

    Also burp the cooling system. If the coolant wasn't filled correctly you can get air pockets in the system. There's a pretty specific procedure for the turbo engines.

    07 WRX TR M5 Garnet Red Pearl w/ Straight PPGs and Cusco front LSD (Agile tune:307whp/343wtq)

    Contrary to pretty much every other engine out there 90% of Subarus with blown HG's end up leaking externally both coolant and/or oil...Obviously if you have an external leak and not an internal one you wont be burning any coolant/oil...As mentioned try what others have suggested such as burping the system, inspecting things etc etc..because obviously worse comes to worse you'll need head gaskets ( which is a somewhat rare occurance on Turbo Subarus..I think Ive seen like 2 Turbo Subies with popped HG's compared to the hundreds of N/A subarus ive seen with HG problems)
