How do you change a thermostat in a Chrysler LHS?

To change the thermostat in a Chrysler LHS, first ensure the engine is cool, then disconnect the negative battery cable. Drain the coolant from the radiator and remove the upper radiator hose connected to the thermostat housing. Unscrew the thermostat housing and replace the old thermostat with the new one, ensuring the rubber gasket is in place. Reassemble the housing, reconnect the hose, refill the coolant, and finally reconnect the battery cable.
