So it's the Punto 60 engine then?
For the easy swap, yes. Look for the engine codes which are dot stamped on the top of the water pump housing. You may need some emery cloth or similar to clean the face up in order to read them - you're looking at the flat horizontal piece on the left front of the engine (looking from the exhaust side) just above the water tube, next to the cam belt cover.
