To change the thermostat on a 2005 Chevy Aveo, first ensure the engine is cool, then disconnect the negative battery cable. Remove the upper radiator hose connected to the thermostat housing, unbolt the housing, and take out the old thermostat. Clean the mating surfaces, place the new thermostat in position (making sure the spring side faces the engine), reassemble the housing, and reconnect the radiator hose and battery cable. Finally, refill the coolant and check for leaks.
