First of all, I don't know all that much about working on Subaru's or any car. Yesterday while driving the Subaru, my wife was going up a steep mountain and it overheated. She found that it was low on coolant and filled it up. She then proceeded to drive it to her destination. She said that the heater would blow hot air while the car wasn't overheating, but would blow ambient air when it started overheating while the heater was turned on. She also complained of some kind of rattling that she had trouble describing and I have not heard yet. I met drove home with her and it started to overheat again. I thought it might be the thermostat, so I removed it and refilled the coolant with water. We proceeded to drive it home 30 miles, but it did start to heat up again at one point and then cool off.
This morning I noticed most of the coolant had leaked out onto the driveway. I refilled it partially and noticed that it was dripping very quickly out, what it appeared to be, the exhaust port of the engine. I started it up and it seems to be running pretty rough now. It was running a bit rough last night too.
Doing a search in the forums has given an idea what it might be. I just wanted confirmation I guess. Thanks for any help you can give me.
