Caution: When opening the expansion tank, hot steam may leak out. After covering the cork with a rag, carefully open it.
Open the coolant cap on the expansion tank. Remove the lower engine cover. Open the drain valve on the lower coolant hose leading to the radiator "arrow".

Refueling
Close the drain valve on the lower coolant hose leading to the radiator. Install the lower engine cover. Prepare the required amount of coolant, pre-mixed in the correct proportions, in a suitable container—Fabia II. Fill the coolant up to the maximum mark on the expansion tank. Close the expansion tank. Start the engine and let it run until the fan starts to run. Check the coolant level and top up if necessary. When the engine is warm, the coolant level should be at the "max." mark, and when the engine is cold, it should be between the "min." and "max." marks.
