Hey Im not sure where to post this. But my heater core seems to be leaking. How do I go about removing it and putting a new one in. how simple of an operation is it?

 

I think there is a tech article on this site and i know there is a pretty good one on sethirdgen.org. But when i removed mine i unbolted the dash from the car and pulled it back a bit to get to the heater core. I didn't feel like blindly trying to remove the top bolt so i took the long but easy way out.
