How do you refill radiator water on a citroen saxo?

To refill the radiator water on a Citroën Saxo, first ensure the engine is cool for safety. Open the hood and locate the radiator cap; carefully remove it, using a cloth if necessary to avoid burns. Fill the radiator with a mixture of water and coolant until it reaches the proper level, then replace the cap securely. Finally, check the overflow reservoir and top it off if needed.
