2007 GT Mustang....Coolant Leaking

[Hydrahotdog44]

I have noticed that every now and again, every couple months, when I check up on the engine, the collant overflow tank will need a almost a gallon of collant. This thing is drinking coolant and I cannot see what the problem is. I have no trouble with overheating or anything, everything runs fine and no visible leaking anywhere. The coolant just seems to disappear. I did notice a sound from the right side of the radiator, like air or something coming out. I dont know. Is this the issue? Thanks.

I'd recommend getting the kit with the dye and the ultraviolet light to find the leak. It might be a crack in the tank or radiator.
