What does it mean when gage inside reads car is hot yet antifreeze is not going down in reservoir or radiator on 1993 Oldsmobile Cutlass Supreme?

It sounds like you may need to replace your thermostat. Even though you have enough coolant in the radiator and overflow reservoir the coolant may not be circulating through the system because the thermostat is not opening. When the coolant can't flow through the engine and radiator it will get very hot and stay very hot. This is usually an inexpensive and fairly easy fix, just purchase a new thermostat and install it or have a mechanic do it for you.
