Hello from Indianapolis, I'm the proud owner of a grand prix but it has a small problem.

It seems my heater core is leaking. Not sure what else it could be. I am not sure where the heater core is located and the process to get to it and remove it. I have searched the forum and scrounged around online but I'm not finding much process related.

So far I found this: How to Replace the Heater Core in a Pontiac Grand Prix | eHow.com

I would be grateful for any information or links to this process. Also, I am not well versed on terms or processes associated with this so in advance please forgive my ignorance. Thanks
