I am trying to figure out what the name and possibly the part number is for the plastic part mounted under the intake on the back driver's side of the engine that the heater inlet hose connects to. My friend's Punto has the top half of the plastic piece missing like the hose is connected to just the bottom half of a plastic fitting. I have attached pictures of the connector from my Punto. Thanks.

Temperature sensor housing

Thank you. If I had just stopped and thought about it I would have been able to come up with it... I can clearly see a sensor... it goes into the coolant... obviously not a level sensor... Ugh... Oh well. Thanks.
