Question about 2002 Buick Century
Drain about 1/4 of your radiator fluid into pan with petcock under radiator. Then follow upper radiator hose and it will lead directly to the thermostat housing. It should have about 3 bolts on it. Just pull off hose, then housing. Thermostat will pull right out. You may or may not get a gasket with new one. If not, you can use RTV silicone for $3-4 and spread a thin layer of silicone around between housing and surface, then reconnect everything. Let dry for couple hours, refill radiator while veheicle is running and make sure thermostat opens. When open, coolant level will drop and you should add more til full. Then your done.

Trace the upper radiator hose to the mounting area on the intake manifold. Loosen the hose clamp on the manifold end of the hose and remove the hose. Pull the thermostat out of the intake manifold.
