That is a later unit. They had temp., sensors in it. Plug them, or get an older one, without them.
Follow the top radiator hose back to the engine block. The thermostat is inside the housing where the radiator hose connects to the block.
ON THE BLOCK. FOLLOW THE TOP RADIATOR HOSE, GOES FROM THE RADIATOR TO THE THERMOSTAT HOUSING. TWO BOLTS
follow your top radiator hose to the engine block. the hose will be attached to the thermostat housing. the housing is attached to the block with two bolts. remove the radiator hose from the housing, remove the two bolts, and gently separate the housing from the block. you will see the thermostat. The above answer is for a V6 engine. If your engine is a V8, follow the lower radiator hose toward the engine. The thermostat, housing & o-ring are one piece.
The thermostat is inside the small housing where the top radiator hose connects to the engine block.
Follow the upper radiator hose to the engine block. The part the hose is connected to is the thermostat housing. The thermostat is under it.
Whether with the Chevy 350 or no, the thermostat is at the other end of the large hose that enters the radiator from the top; in the top of the engine block. Just follow the hose from the radiator to the thermostat housing.
The thermostat is located on a 2003 Oldsmobile Alero in the thermostat housing. The thermostat housing is located on the rear side of the engine block.
Check where the top radiator hose enters the block. There should be a housing that can be removed with 2 bolts. That should be the location of the thermostat.

The top radiator hose connects to the engine through the thermostat housing. Remove the radiator hose from the housing, remove the two bolts that hold the housing to the block, remove the thermostat from the housing, clean the housing and the block, put a new thermostat in (following the directions for orientation as specified by the box with the spring assembly TOWARD the engine.) Then after you have re-installed the thermostat housing and the radiator hose, add coolant and be on your way. While you're at it, check the radiator and heater hoses for brittle rubber or bulging spots and replace the hose if there is any evidence of damage.
On the passenger side of the car, trace the hose from the bottom of the radiator upwards. This hose is tapped by another hose from the coolant surge tank. Follow the hose towards the engine block. The thermostat is located at the end of this hose. There are two small screws that hold the thermostat housing to the larger housing. Apply penetrating oil to these screws if they are tight. Remember to drain the radiator of coolant before removing the thermostat housing. There is no gasket between the thermostat housing and the larger housing. When remounting the housing, use the paste that is specifically manufactured for this purpose. It is sold at any auto supply store. Remember which direction the spring of the thermostat points before you remove it.
Just follow the upper radiator hose to the engine block. The thermostat is inside that small dome-shape that the hose is connected to. Remove the 2 bolts and it's inside.
