195 is a safe temp for an engine. Many manufacturers use that thermostat in modern engines. Boiling is 212 degrees f and that is with no pressure in the cooling system.
As A.J. posted with a normal radiator cap (15 psi) the boiling number is closer to 240 degrees and you are asking about a 195 degree engine coolant temp. No worries and if the engine likes it , listen to the engine.
Told a Big Boss at my old job one time, "The Engine is TRYING to tell you something, are YOU willing to listen?" Dead quiet in the room for about a minute and the Big Boss said, "Yes I Am" and we had a successful engine program. Never got fired for telling the truth in 39 years but not everyone was as smart as that guy was.
