What exactly does the thermo vacuum switch do?(first switch by the top front of the engine/valve cover with two vacuum lines attached to it) and, how do you test it? I can not find the info on it and, I think mine is leaking...by the name itself, I suspect it applies/cuts vacuum to ? at a certain temperature.
