85 to 95 deg C, depending on ambient temp
Thermostat or water flow problem.
Possible causes of gauge not working. Faulty gauge Blown fuse. Open circuit in wiring to the gauge. Temprature transmitter in engine faulty. ( most probably the actual fault ) Lack of coolant in the engine.

Either the gauge or the sending unit is faulty.
The answer depends on which gauge you are asking about: if it is a thermometer, it could be used to measure the oven temperature. If it is part of a clock/programmer, it tells the time of day and can be used to switch the oven on and off automatically.
replace temperature gauge
Fuse location for temperature gauge for a Malibu
Could be a failed engine coolant temperature sensor. Easy enough to replace and not too expensive.
