Thanks for the info. Leave it up to the Germans to make something like antifreeze a topic of debate.
I think this weekend I will be flushing it out DIY. Other than the Snap-On kit, anyone know of a good "how to" that's published on doing it right, or tools that can aid in keeping air out? What about pressures? If you pull a vaccuum on the system, is there a chance of pulling too much and collapsing something?
I did talk to the dealer, who gave me a run-down on the fluids. Apparently, the original Porsche fluid is green - somewhat in color to prestone and is the "lifetime" stuff. They actually didn't want to quote me a price on them flushing it, as they said it was "lifetime" rated. (yea right). Then I guess there is an Orange fluid also which appers to be what I'm filled with now, that's a DexCool replacement, and now the new Porsche fluid is pink/red. The pink/orange should be ok together..but I'm not going to take a risk on mixing it into yet another color.
Why this can't be simple I have no idea, but I'll flush it out and replace it so that I will finally know what the hell is in there.
BTW - Milwaukee area dealer wants 260.00 labor, plus parts to do a flush. They said their procedure is to let the fluid gravity drain, and then they use a machine to purge it, and then they refill. They budget at least 2 to 4 hours to completely drain it.
Thanks again!
