I have the 2003 Subaru Forester 2.0 xt, automatic and has 90 000km on the clock. I got it second hand on Saturday and i drove it back to my house which is 600km away. All went well but i am having a problem, when the car and the air around are both cold i get nice performance and can feel that beautiful Subaru motor, turbo and intercooler pull that drew me to this car, but as soon as the car heats up a bit after maybe 5 min of driving or if the car sits in the sun. The power disappears. It may be wrong to say that the power completely disappears but it fells like the turbo isn't pulling.
One other thing. As soon as i got it home it did a full service on the car hoping that this would sort the problem. That was fuel filter, air filter, oil filter, oil change, spark plugs changed. This didn't sort my power problem. I took it for a spin around the block and was pushing it a bit trying to see what's happening with the power. When i got back to the house there was steam pouring out of the bonnet. The heat gauge seemed fine and was half way. I opened the bonnet and there was coolant everywhere. The top of the radiator where the black part joins with the aluminium (The aluminium is curled over the black top part holding it down). There was water coming out of there. It seemed to be the only part that was loosing water. Please guys help me find what the problem is. I presume that the top tank on the radiator maybe needs replacing and i have taken the radiator out of the car but i don't know what caused this to happen and would hate to get a new top tank and it happens again or it blows something else. Please guys i love this car and don't feel that the expertise needed are available here in my country to sort this out.
