you must inspect the engine carefully to see where it's wet- use a flashlight and a little mirror- especially look under the engine- and around the water pump- the wet spots should tell you- run the engine and look under the engine and under the hood- nothing on the ground? nothing on the carpet inside under the dash? have you had recent work done on the cooling system, hoses disconnected, etc.? It's not magic- that water/coolant is goin' somewhere- you say there is no water in the engine oil- is there any oil in the water/radiator?

If water resivoir is needing to be filled regularly but you do not see any wet spots on engine or ground below it the leak could be evaporating off before it has a chance to drip. With engine cool do a pressure test on cooling system. This will cause it to leak and with engine cool it will not evaporate off. With age of your car I would suspect water pump if it hasn't been change in around 80000 miles. Remove belts and plastic guards off front of engine before doing pressure test. Inspect weep hole on water pump. If there are signs of dried coolant or if weep hole leaks when you do pressure test replace water pump. Inspect all radiator/heater hoses too. Other than the loss of water is it running ok? No white smoke out the exhaust? No missing?

It's not all that hard. Just need to take your time. And be sure to get all your timing marks lined up. I would suggest replacing the timing belts and pullies also while you are in there. That is if you not sure when they were last replaced. I say belts because I believe yours might have two belts.
