I'm assuming you have the correct thermostat, but you should always double check. Some other things that may or may not be causing the problem could be: Your radiatior is clogged and the antifreeze isn't circulating properly. You may not have enough antifreeze in your radiator. You may not be getting enough airflow through your grille to the radiator. Your electric cooling fans may not be working properly. Your radiator cap isn't maintaining proper pressure. Your ignition timing could be off, but it believe it's computer controlled on your vehicle, so that shouldn't be it. Hope this helps! Good luck, and don't get frusterated, you'll be able to find it.

The 1993 Oldsmobile Cutlass Sierra thermostat is located on the front of the engine. You can follow the water supply line from the radiator to the thermostat housing.

Low coolant? Cooling fan not working? Water pump not circulating water? System airbound? Radiator plugged or restricted? Thermostat not fully opening?
On the 3.3L V6 it is under the radiator cap.
Replacing a thermostat on a 1999 Oldsmobile Cutlass is very easy to do. First you will find the thermostat by following the upper radiator hose. It is under the exhaust crossover. The thermostat has two 13 mm bolts holding it in place. Take the bolts off to remove the thermostat and replace with a new one.
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.
May be a defective thermostat or heater core
