Question about 1993 Oldsmobile Cutlass Supreme
Fan relay switch is located in the rad. so is level sensor.
3.1's have history of blowing intake gasket. puts water/coolant in the oil.
check rad . check water pump. you can run without a thermostat, cheap to replace,put a new one in.
Check the rad fluid level. Just because the res does doesn't mean the rad and engine is.topped up.. Do not pressure test the system chance you may blow the intake gasket and force the coolant into the oil.
A good shop can hell!

Usually near the thermostat.
By the way, remove the thermostat and drive around with the car. If it still overheats, might have some other problem, like you said, temp sensor, or some kind of electrical problem.
