Question about 1989 Buick Century
Follow the left(closest to transmission) radiator hose to where it connects to the engine. It connects to the thermostat housing. This is removed by undoing 2 bolts that hold the housing in place. Vehicles with cruise control have a bracket on the housing which also needs to be removed.

Hi Wilson, Follow the upper radiator hose to the engine. Where the hose connects to the engine you will find the thermostat. You will see some sort of housing for the thermostat at that location. You say your Buick is overheating so we need to find the cause of this. If you see white smoke, especially at startup, a white foamy substance under the oil fill cap, oil level is overfull, or you are loosing coolant with no apparent leak, then you may have a blown head gasket. If you are experiencing none of these symptoms, is your water pump leaking or noisy? If the water pump is ok, then is the cooling fan working properly? The fan should run continuously with the A/C on. It may very well be the thermostat is sticking closed. Drain the radiator, remove the thermostat, leave the thermostat off and replace the hose. Turn the heater control to hot, and flush the entire system with a good commercial flush product. Drain the water from the system, remove the upper hose and install a new thermostat. Pour in a 50/50 mix of the correct antifreeze and distilled water. Bleed all air from the system keeping the radiator full at all times. When doing all this inspect all hoses an replace if necessary. You have a 21 year old car and a complete cooling system service is needed. Now is the time to replace any suspect hose. Also be sure and clean the front of the radiator off. Remove any bugs or debris that are stuck there.
