How do you change antifreeze in Fiat Bravo?

To change the antifreeze in a Fiat Bravo, start by ensuring the engine is cool and then locate the radiator drain plug to release the old coolant into a suitable container. Next, close the drain plug and fill the radiator with a mixture of new antifreeze and distilled water, following the manufacturer's recommended ratio. Run the engine for a few minutes to allow the new coolant to circulate, then check the levels and top off if necessary. Finally, dispose of the old coolant responsibly, as it is hazardous to the environment.
