To change the thermostat in a Lexus ES 330, first ensure the engine is cool and disconnect the negative battery terminal. Drain the coolant from the radiator, then remove the hoses connected to the thermostat housing. Unbolt the thermostat housing, replace the old thermostat with a new one, and reassemble everything in reverse order, ensuring to refill the coolant and check for leaks. Always consult the vehicle's service manual for specific instructions and torque specifications.
