Check your engine oil to see if it is foamy or looks cloudy not clear, if so it could be a head gasket leak, If not it could be a leaky radiator cap or a leak somewhere else in the cooling system. If you see no leaks and are losing water it could be a leak inside the engine, this would show up in your oil
I had a similar problem, it was a water pump (expensive)
