New 2003 bird owner - trying to run down a list of issues with my new car. Fixed an obvious one as there was a crack in thermostat housing. Replaced that, hoses and stat. No more steam coming from under hood, but I still have a coolant leak as it seems to be going somewhere. I am noticing a bit of fogging on inside of windshield and am thinking (but really hoping that it is NOT) a leaking heater core. Any other places to check before I assume the worst? Going to check hoses where they attach at firewall for any obvious leaks, but I guess my real question is: Has anyone replaced their heater core? Since I have not found ANYTHING online about this (youtube, google, etc) I'm guessing it's not common. Does the dash have to come off? Steering column?
