Before I begin, let me be the first to "offically" nominate myself for "Stangnet's Biggest PITA"!
As those of you who know me might know, one answer is never good enough for me. After weeks of heating/cooling issues/questions, I finnaly went to a shop to have a carbon test done today, as my car overheated again last night and puked all it's coolant (OK, it was after a 0-60 stoplight race, I deserve what I get )
It seemed to me like the stat, as every morning, it will heat up to 210* before it opens and goes back to 180*, so I just thought it would not open sometimes, and overheating and puking would result. At the same time, I thought it would be another HG.
Either way, no water in oil, no snot foam in vavle cover, no coolant smell in exhaust, but I wanted a definite answer., so I went to the shop.

Now, they did the carbon test w/ the two chambers of blue liquid in the turkey-baster thingy (I'm so smart, right?), and after a dozen or more pumps, there was no color change at all in the liquid, still blue, not green as they said a positive result would be.
Now, just to put me completely at rest, this test is supposed to be done w/ the engine off, or on? Is it a pretty fail-safe test?
They agreed w/ my guess of a faulty stat, and my Mr. Gasket should be delieverd today, so the *should* solve my problems, but I guess we'll see.
Any thought/opinions?
thanks alot guys.

I have not done this test before, but I would think that as long as the car had not been sitting for a few days that it would still be reliable. I can't see unburned HC evaporating though, so I would think you could run the test either way.

Maybe someone else has more experience here than I do, but those are my thoughts.

You just might have this sorted out now!
What temp stat did you get?

Good luck jaymac

I got a 180*, which I have now, but I got a balanced Mr. Gasket, so hopefully it will perform a little better.
Thanks!

I run that same Mr Gasket 180* t-stat and it rocks. For the emissions crowd they also have the same t-stat but in 195* as well. Car always runs nice and cool (even cooler now that the weather is cooling off and I moved back up north).
