Loosing Water And Dont Know What To Do

[jdclemons]

Hi, I am loosing water from my radiator. I can fill it up about 50/50 antifreeze and water drive it down the road a couple of miles today and a couple of miles tomorrow then it low on water. I have change the thermostat which was no change. I have true dual exhaust and there is no steam coming out either tail pipe. I dont see any physical water hitting the ground so im puzzled. It is not mixing in the oil either. No water is in the passenger floor board. Does anyone know where it could be going.
