How do you replace the thermostat located on a 1989 Pontiac Grand Am?

the thermostat is right on to of the engine just follow the top radiator hose back to the engine there are two bolts to remove. take the old thermostat off clean the surface area of the thermostat housing. apply silicone and gasket. then put in new thermostat and bolt back down(just dont over tighten the bolts the housings are made from aluminum and will crack)
