,Water temp going high, normally faulty thermostat in block by water outlet to rad. Topping up frequently could be due to temp getting to high and opening the thermostat on radiator. Other causes, pump not working properly, fan not cutting in, water system needs flushing out, head gasket weeping, pushing air into water system and putting to much pressure on radiator cap which in turn opens and lets water out. I would start with thermostat on top of engine. It will have temp on it. Take it out put in saucepan with water and bring temp up to that of thermo stat and see if it opens at right temp. If head gasket is weeping you will not always get water in the oil, this depends on just where it is weeping. Good luck
