Radiator Problem or is it something else

I have a 04 st and lately I have to watch my water level very closely. about every two to three days I have to add about a 1/2 gallon of water. there is no signs of any leaks anywhere any ideas????

Get a cooling system pressure checker and check the system both hot and cold. Also check the pressure cap. At this point it would be anyone's guess.

Hose/water pump/radiator/thermostat housing/head gasket/????

I had to replace the thermostst and top and bottom of the mounting ( the lower cracked) so I don't thin its that. Hoses all seem in good shape.I could deal with a radiator replace or maybe even the water pump. I would hate to have to deal with gaskets
