Where do i fill in coolant in Ford Fiesta?

To fill coolant in a Ford Fiesta, locate the coolant reservoir, which is typically a translucent plastic tank situated near the engine. Remove the cap, and pour the appropriate coolant mixture (usually a 50/50 mix of antifreeze and water) into the reservoir until it reaches the "MAX" line. Ensure the engine is cool before adding coolant to avoid injury or damage. Always consult your owner's manual for specific instructions and coolant type.
