Pretty unreliable I'd imagine. :)) Sampling the gas from _above_ the coolant in the top tank is the way it's supposed to be done! -- John H

The "easy" part is fine, but the "reliable" part isn't so great. I haven't had a lot to do with them, but as I said in another post I mostly consider them to be a gimmick as the ones I have used haven't been very reliable at all. In fact, I suspect the fact that radiator shops seem to be the most common users of the things speaks volumes for their usefullness. > The TK test is supposedly a very accurate test essentially designed to see > if there are traces of exhaust gasses in the radiator system and we all > know what usually causes that don't we? The last one I used was probably 20 years ago now, and while it's possible that they might have improved by then I'd have to see it with my own eyes. Back then they weren't much better than guessing, and getting a fake positive was just about gauranteed as soon as you opened the box. I remember trying the one we had at Repco on near new cars with no problems and it would return a positive reading almost every single time. Whether it was actually detecting exhaust gas in the coolant or not I can't tell you, but if it was then it was in such minute amounts that it wasn't a problem as far as the car was concerned. I suspect it wasn't. > Depending on the information available from the customer at the time, a > radiator specialist will check for other problems before performing a TK > test.

I don't know what radiator "specialists" are like in your part of the world, but down here most of them aren't interested in looking a car and trying to tell what's wrong with it. That's the mechanic's job. All the radiator blokes want to do is fix the radiator. -- Regards, Noddy.
