I'm running Zerex Extreme (OAT) 40% and water 60%.
Yes some water wetter.


If you are runing the stock T-stat it does not fully open until ~192-194.

It is rated to start opening at 188. (Also it's the same one most aftermarket companies sell as a 180 t-stat )


2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
