No problem with 108 C (226 F). That is normal for these engines. Gauge is usually straight up.

You wouldn't want to see any "cycling" of the temps., it's showing CHT (cylinder head temp) and the objective is to keep that as stable as possible.

Thanks for the reply. The hose going to the thermostat is cool to the touch, the other hose is hot when engine is at temp. I guess the when the stat opens it pulls coolant from radiator into engine. Is this correct flow direction or vise versa?

Yeah, that's what the diagram shows.

Small hose there is always flowing, and the radiator returns that way when needed. Both go from there to the water pump for distribution.
