Water is indeed the best coolant. But other considerations make it unwise to run straight water. Corrosion is a culprit anti-freeze of the proper sort will virtually eliminate. Alfas spending there lives in warm climates can have serious corrosion issues if only water is used. The best coolant mix is a modern anti-freeze of at least 30% concentration, higher if freezing can happen, along with distilled water. Stay away from water wetter and waterless coolants.
