Blown Head Gasket! i had same issue. trust me. and don't have any compression tests or hydro carbine tests done it will show up clean. its weird with Subaru's. buy a junkyard engine and have a backyard mechanic put it in. it'll cost $600 with labor. junkyard engines are cheap. find a low milage one.
Blown head gasket?
more than likely you need a new radiator for it, when you install it back flush the engine.
My 2001 Nissan frontier 3.3 v6 engine is overheating. I changed the thermostat but it still overheats.
Sell It!!!!!
If the radiator or reservoir cap is bad it could cause overheating because the system will not build up the proper pressure. Also the fan clutch could be worn out which would keep the fan from spinning fast enough to cool the radiator.
check the heater core stopped up radiator
Flush out the radiator, it could be pluged to the point its not cooling and will blow another hose or worse , head gasket. A good flush would be my choice. Good luck rick
Check for bubbles in the radiator engine warm with the cap off,if you see a continuios build up of air or violant purging you probably have a blown head gasket or cracked head. Talk to me.
water pump. thermostat.
Remove the Radiator and have it serviced if they are able to. If not you will need to replace it, would be a good time to replace the Radiator hose's as well. Hope This Helps.
Either the water pump impeller is loose on it's shaft, or you have a leaking head gasket.
its not very common that u have to replace all that because when a car overheats it ruins the engine so u either rebuild it or replace it
