High high does the gauge go up? mid way, 3/4 way? That would be normal. The thermostat opening temperature is about 195-205 degrees. If you are not getting heat from the heater then you may have a plugged heater hose or a plugged heater core. To check the heater system, while the engine is running and warmed up, touch the heater hoses to see if they get hot. If they are hot to the touch then water is flowing through the heater. Also make sure that you bleed the cooling system correctly . There should be 2 air bleed ports in the cooling system. One by the t-stat housing and the other above the water pump area.
