The reservoir is going empty due to a blown head gasket most likely. You will need to have the system pressure tested first to make sure the radiator and coolant reservoir is not leaking under pressure. I suggest having a qualified technician, like one from YourMechanic, diagnose the coolant leak firsthand for an accurate repair.
