Maybe another gasket is leaking? You need to check all the hoses. Maybe a heater hose or bypass hose? Hole or crack in the coolant reservoir?

TDolby Thank you! I will check and see what I can find. It's starting to irritate me as I am a single mother of 3 boys and just need this fixed asap since it's cold.

Plastic fittings around thermostat hoses. About 1/2" tubes. The plastic gets hairline cracks and leaks. Very simple fix. Autozone may help you see the problem. It's on top the engine on passenger side. Coolant evaporates so fast you don't see the problem.
