It may be ok. Remember, some of the water will stay in the engine block. There are drain plugs on the engine. Regardless, what I recommend is to replace the hose, refill the system with a 50/50 mixture of coolant and water. That way you will be fine. Also, coolant also boils at a much higher boiling point. Thus, it will help pritect the engine in the summer plus it helps prevent rust.
Let me know if you have other questions.
