That's a CLASSIC! I'm going to steal that one! I agree with above, fill it up with antifreeze, if it leaked out that fast it's going to be obvious where it's leaking.
Fill it up with water first, don't waste the antifreeze.
Yea I agree don't waste coolant looking for the leak (s). If I remember correctly aren't the radiators on these aluminum with plastic end tanks? When my radiator failed on my GTO it was a 1.5 inch crack on the plastic end tank. I lost most of my coolant and when the tank failed my car was parked and not running, but I had just gotten to the office so the car was at operating temp. Sometimes the crack is obvious but sometimes its hard to see exactly where the crack is, and if it is the radiator, don't replace it with a radiator of the same design go with a quality all aluminum radiator especially if your A/T cooler is in the radiator. Assuming that the cooling system is in decent shape I would check the radiator first, then the hoses before going out and buying a water pump,i.e. assess, diagnose, then repair or replace. On a side note whoever had the bright idea of making a radiator with plastic side tanks needs a good beat down.
I had that same problem with a radiator on my Expedition one time with a crack in the plastic tank on the end of the radiator. I could not see the crack, could not see any fluid leaking from it while running cool, but when it got heated up, the crack expanded and that was when the fluid leaked out under pressure. That would not explain all the fluid being dumped at once, but if it is allowed to go on, it may not be noticeable, since it would be leaking mostly while driving hot. I replaced that radiator with another, also with a plastic end tank and now 4 years later there is another problem with the transmission fluid mixing with the coolant.
