Ok. HAh This is my first time working on almost any car so work with me here

I took the thermostat housing off and removed the gasket. Now on the housing there was a threaded sensor with two wires connecting to it. I took this out (shouldn't of done it). Now I don't have a seal on the car. Should I purchase locktite or something or could I use the same stuff that you use to seal the air lines?

Would the same stuff you use for the air lines work?
