thermostats are to keep the engine heat at least at the thermostats design temp ... it doesn't keep it from getting hotter than that, just keeps it from getting colder .. if you have a 160 then everytime the temp gets below 160 the thermo closes and stops the flow of coolant until it gets back up above 160 ... if it gets above the thermostat design temp, thats a whole nother problem ... unless the thermostat is stuck closed, or restricted then it has nothing to do with the engine temp getting to high.
Your 200 degree operating temp could be a bad thermostat or an inaccurate guage reading, or an inaccurate thermostat, or anyone of the other million reasons for overheating problems
