Depends on what size engine you have, and what year of Grand Am you have. Mine is a 1996 with a 2.4L engine. So my thermostat is located in the bottom radiator hose, where it goes into the water pump.
To replace the thermostat on a 1997 Pontiac Grand Am 3.1, first disconnect the negative battery terminal and loosen the clamp on the radiator hose. Next, remove the mounting bolts from the thermostat housing and insert the new thermostat.
Cheap-it's a 5.00 part you can replace yourself.
