1997 pontiac sunfire overheats?

[Steve]

cant see a leak, fan ok, no oil emulsification, no water in exhaust. Help

I see it is common but not been able to find a real cure..

It is loosing water but I dont know if it is because it is too hot and looses it from expansion bottle or if it looses it then overheats??

Help
Thermostat ok. It has regular oil changes too so I know it isn't loosing it into the oil, no emulsification..

known to have leaky head gaskets, try a cooling system pressure test
