theres alot of places for water to leak on an engine, if its from the engine (rather than the radiator) somewhere it'll be the waterpump (mildly expensive) or some random heater hose / water line. (not so expensive).
coolant strength (or lack of) wont cause leaks in the time frame you are looking at, although lack of inhibitor will cause rust in pipes / water galleries in the long term.
half coolant half water is a good mix.
BASU!
