Blown head gasket?
A thermostat that is stuck in the closed position is a very common cause of overheating. A new thermostat should be installed every time the coolant is changed.
Either the water pump impeller is loose on it's shaft, or you have a leaking head gasket.
Remove the Radiator and have it serviced if they are able to. If not you will need to replace it, would be a good time to replace the Radiator hose's as well. Hope This Helps.
If your 1995 Oldsmobile Aurora keeps overheating and the issue is not the thermostat or the water pump, it could be the cooling fan. It might also be the radiator (leaking) or the hoses between the engine and radiator, or the shroud could be clogged or damaged.

Stuck thermostat, clogged radiator.
If it's overheating, it cold be thermostat, radiator or possibly other problems. If it's not overheating it could be the coolant level sensor.
The most common cause of overheating is a thermostat stuck in the closed position. However, other causes are: faulty water pump, clogged radiator, clogged hose(s), coolant leak or a broken drive belt. I had a 1987 legend with around 160K that was overheating. Antifreeze would boil out of the overflow. I changed my radiator and it fixed the problem.
