pump the coolant loop up by putting a pressure checker on the radiator, and watch where's it gushing from....it it's just a hose replace it, hopefully it's not the heatercore, but may not be such a tough job on your Pontiac.

Sound like a heater core leak and it coming out of the evap. Drain onthe firewall. But im not there so i cant be sure. Have the cooling system pressure tested and observe where the leak it coming from

Meanwhile don't let anti freeze level too low. At the store u can get pre mixed anti-freeze that's already to go.

Look with a bright light and feel around to find the leak, might be something so simple to fix. Loose clamp, short section of hose you could do yourself. When you run the engine, and get it warmed, it will pressurize itself. Top it off with fluid cold, run it till operating temp. Then shut it off at that time trace leak find out source of leak.

there might be a "convenience" shroeder valve near the high-point at the heat exchanger...use this to 'belch' the system of air, else take off the top hose to the heat exhanger enough time to let the air out~

You don't want to drive around with low coolant. It's a sure way to blow your head gasket from overheating. Fill the coolant reservoir, get the engine up to temperature, try to spot where it is leaking from. Bleed the air out using these instructions. http://www.gaownersclub.com/forum/faq.php? faq=maint_repair#faq_cooling_serv
