If you have a 195 degree thermostat and your aftermarket gauge shows 190 you are fine. If it gets up over 205 then you should be concerned.

With the engine cool, pull off the end of the upper radiator hose at the thermostat housing, remove the thermostat. Start the engine. If coolant flows out of the housing the water pump is likely okay. Or you can remove the end of the lower hose at the radiator and start the engine to see if the pump is working and also that the radiator isn't clogged. Good luck!
