How do you change thermostat on Fiat palio?

To change the thermostat on a Fiat Palio, first ensure the engine is cool and disconnect the battery. Drain the coolant from the radiator, then remove any components obstructing access to the thermostat housing. Unbolt the housing, take out the old thermostat, and clean the mating surfaces. Install the new thermostat, reassemble the housing, refill the coolant, and reconnect the battery.
