Toyota Repair: thermostate toyota camery 96, radiator hose, toyota camry

Question
Hello
I had overheating. I change two hoses form radiator and no licking form anywhere. Water and oil is great and they are not mix.  I think next step belong thermostat or water pump.
Is that right or not?  Is this easy to change thermostat?
Can you give me an idea of what the steps are to change this out?  
It is a 1996 Toyota Camry and Four cylinders(LE)
Thanks so much.

Answer
Yes, the next step would be to replace the thermostat, it's located where the lower radiator hose comes from the engine, there are two 10mm size nuts attaching the housing, remove the housing the thermostat is inside, if there is still an overheating problem I would recommend having the radiator checked for a possible restriction.
