first when car is cold open radiator cap add if needed, then borrow a rad pressure tester, or have a local shop pressure 80% of the time its one of the many small heater hoses leakink with pressure you look under car for anti freeze leaking. if system is full and temp gets hot make sure fan clutch is good when engine is hot rev engine 2000 rpm it should feel like a big house fan if fan balde is not pulling air clutch is bad, also peek between radiator and ac condensor ive seen leaves block the whole radiator.if thermostat is bad on radiator hose will be cold and one hot check at operating temp. this indicates a stuck closed thermostat, the older car are also famous for clogged radiators drain some coolant and look inside radiator if it looks like the tubes are blocked with corrosion and mineral deposits replace radiator also check the oil stick and make sure the oil is clean. milky white oil is sign of coolant leaking inside engine ex bad head gasket or bad intake gasket. if you dont understand get it to a shop for a estimate and diagnosis overheat is a killer of engines. good luck g d
