Isn't the function of the little TVS (Thermal Vacuum Switch) to increase idle RPM when engine heats up? Sounds to me as if GM designers once again had their heads on straight!

Mac,

Yes, it was, but it was more to allow the low idle for emissions than to help cooling. In the current iteration, I am using the hole where the TVS was for the fans temperature switch. I believe I will come up with a better answer in the future.
