Before I begin, let me be the first to "offically" nominate myself for "Stangnet's Biggest PITA"!:rolleyes:
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).
