Where is the thermostat on a 1989 olds cutlass ciera 3.3 motor?

On a 1989 Oldsmobile Cutlass Ciera with a 3.3L motor, the thermostat is located near the engine block, typically at the end of the upper radiator hose. To access it, follow the upper hose to where it connects to the engine, which is where the thermostat housing is situated. You'll need to remove the housing to replace the thermostat. Make sure to allow the engine to cool and drain some coolant before starting the procedure.
