How do you drain a radiator of citroen berlingo?

To drain the radiator of a Citroën Berlingo, first ensure the engine is cool and turn off the ignition. Locate the drain plug at the bottom of the radiator, usually on one side, and place a container underneath to catch the coolant. Open the drain plug and allow the coolant to flow out completely. After draining, close the plug securely and refill the radiator with the appropriate coolant mixture.
