How do I change the thermostat on my 1998 Buick century?

where is the thermostat on my 1998 Buick CenturyHow do I change the thermostat on my 1998 Buick century?it's located at the opposite end of the upper radiator hose, under the ball shaped metal thing, inside it's own mounting container. Remove the upper radiator hose (large one coming out of the radiator on the driver's side) and then the two or four bolts that hold it down. Careful if it's tough as oftentimes it will strip the screw mounts of the mounting container. Then you'll have to remove the two bolts that hold that on,all the while getting radiator fluid all over.

MAKE SURE TO DRAIN SOME RADIATOR FLUID FROM THE RADIATOR, and that the CAR IS COLD.

Replace the gasket, and use some silicon gasket sealer on both surfaces for trouble free installation. Also this holds that darn gasket in place better as you tighten up. Don't over tighten as you need to let the heat expand first, after running to check for leaks (about 5 minute run-time) then tighten a little if need be. hope this helps
