How do you change a 1998 Chrysler Concorde 3.2 thermostat?

To change the thermostat on a 1998 Chrysler Concorde 3.2, first, ensure the engine is cool and disconnect the negative battery cable. Drain the coolant from the radiator, then locate the thermostat housing, which is typically at the end of the upper radiator hose. Remove the housing by loosening the bolts, take out the old thermostat, and clean the mating surfaces. Install the new thermostat, reassemble the housing, refill the coolant, and reconnect the battery.
