Over heating problem help me out

I fill them up thru the upper radiator hose. Then, when their nose is up in the air, you can finish filling them and bleeding them at the radiator bleed. (since the thermostat is at the lower hose connection to the bottom of the engine) After it is full and bled, you can find if it leaks behind the water pump or at the head gaskets. You will not solve this with aftermarket parts so, I recommend the independent subaru specialists be consulted as they have had to improvise.

Low coolant will cause over heating and no interior heat. Check coolant level. If low fill it back up then check for the leak.

I think I just said that and gave the procedure because they seem full but arent. After trying and getting them hot, you have to wait a 1/2 hour with it shut off for the t-stat to open if you do not fill it thru the upper hose first, by then, you may have already damaged it beyond gaskets only.
