To change the thermostat on a 2003 Pontiac Montana, start by ensuring the engine is cool and disconnect the negative battery cable. Drain the coolant from the radiator, then remove the upper radiator hose connected to the thermostat housing. Unbolt the thermostat housing, replace the old thermostat with a new one (making sure to align it correctly), and reassemble everything by reconnecting the hose and refilling the coolant. Finally, reconnect the battery and check for leaks after starting the engine.
