What does the coolant temperature sender screw into?
1999 Ford Ranger 3.0L V-6 Flex Fuel
I have a hole in my cooling system that I can see, but do not know what to call the part that has the hole. It's a metal part that the temperature sending unit screws into. A hose leads from the bottom of it to the bottom of the engine block. I have managed to find a variety of forum threads and am pretty sure I've managed to identify the temperature sending unit (which supplies the reading for the in-dash temperature gauge) correctly, but haven't managed to find the name of the part with the hole. Can anyone tell me what part it is?
