Yes, the test actually draws in the
air in the top of the radiator through a test liquid in the tube, and detects for exhaust gasses.
If the test passes, you can pour the liquid back into the bottle. From what I remember, the kit will do quite few tests even if you do not reuse the liquid. I used it once, then donated it to a Club I am in.
The liquid does have a shelf life of a few years, and should not be stored in an unheated garage/area.
Another option is to call your local mechanics/radiator shop and see if they can test. May cost a little more - who knows.
