Thread: New Here- 99 GTP Probs- need help- thanks

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

Good to be here.

THE ONLY WAY IF IT WERE YOUR HEATER CORE LEAKING U WOULD HAVE ANTIFREEZE LEAKING INSIDE YOUR CAR AND YOUR WINDOWS WOULD FOG UP. TO GET TO IT YOU HAVE TO REMOVE THE CENTER CONSOLE WHERE THE SHIFTER IS AT AND IT SHOULD BE BEHIND IT. ITS EASIER TO GET A HAYNES MANUAL FROM ADVANCE AUTO OR SOMETHING AND READ UP ON THE EXACT PROCESS. IF YOUR LOSING ANTIFREEZE AND CANT SEE WHERE ITS COMING FROM ITS MOST LIKELY YOUR LIM GASKETS LEAKING COOLANT IN2 YOUR MOTOR. HAPPENED 2 ME. HOPE THIS HELPS IF YOU HAVENT RESOLVED IT YET.
