Hey bud, welcome to the forum. Take a few minutes to fill out your profile. It gives us information like, what year your Corvette is, in case you don't specify the year in the opening post.
Couple questions, did the fluid disappear with it just sitting in the garage or did it disappear after the car was driven?
Have you checked your radiator fluid level and is the level around 4" from the bottom of the filler?
What is the operating temp of the engine?
Have you filled the tank, driven, came back, and looked under for drips or signs of coolant on anything? Puddles? If you have a break in a head gasket and are burning it there might be smoke and the exhaust might have a sweet smell to it.
Also, maybe check the oil dipstick for white milky residue, indicating a crack and coolant entering the crank case. This would cause the fluid level to drop, meaning the overflow in the bottle would be sucked into the cooling system to compensate for the loss.
