I have a 1988 Iroc and it loses about 1 gallon of antifreeze every month. There are no coolant puddles under my car and I have checked the little hole on the water pump and it does not leak. I can't understand it? I have two other cars that never need to have the coolant replaced. Any ideas would be greatly appreciated. Thanks.
I have (well engine blew up ) but a 91 Firebird 305, had never used a drop of anything, but then as it was ready to die, it leaked water somewhere,. and used oil. the water/oil never mixed so the internals were fine. I think my waterpump was leaking as upon removal there was a rusty looking stain where water had been running for years... heheh, turned out that my waterneck and thermostat were leaking too. a 91 isnt so new anymore...
Check your heater core too. Theres a little tube that will let the antifreeze drain while you drive, it should be on the firewall somewhere. If the core just has a pin hole it might not leak while the car is cold. You should just get the cooling system pressure tested and if theres a leak it will show up right away.

I had my Coolant Pressure checked and I had a wierd water pump problem. It only leaked while the engine was running and burned off before it hit the ground. Repalced the water pump and I have not had a problem yet.
Thanks for your replies.
