How do you replace the thermostat located on a 1997 Chevy Camaro RS?

open the radiator cap to release any pressure from the system. Follow the top hose from the radiator and unbolt the two 14 mm bolts holding the thermostat housing in place. Remove the thermostat out of the housing. I replaced mine with a fram 195 degree fail safe (when fails stays open not shut)thermostat. Reinstall making sure you use proper gasket and proper thermostat.
