Thermostats have been known to be bad out of the box, more common now that it used to be.

Should run right at 80C, or 85, depending on application, 95 is too hot.

Check hose condition, fill state (you could be low on coolant if the engine "burped" air after you filled it), and the rad could be crudded up. If you have an aluminum radiator, suspect it as the culprit. You can remove it and have it checked at a radiator shop for flow, or CAREFULLY check to see if it is uniformly warm after running. Cold spots indicate plugging.

Also check that the visco clutch is working -- you should hear the start to roar as the engine gets above 90C, and the aux electric fan must come on at 100C or so.
