To change the thermostat on a 2002 Chevy Trailblazer EXT, first, ensure the engine is cool and disconnect the negative battery cable. Drain the coolant from the radiator, then remove the thermostat housing by unscrewing the bolts. Replace the old thermostat with a new one, ensuring the gasket is in place, reattach the housing, and refill the radiator with coolant. Finally, reconnect the battery and start the engine, checking for leaks.
