Have checked physically that you are actually overheating or just basing yourself with the gauge? such as boiling when you pull over-if not could be low on coolant, water pump impeller and coolant temperature sensor

If you are losing heater output ( heater on vents blowing cold ) when car is overheating stop looking and find someone to do your head gaskets...
