Well, back to my thermostat issue. I have ordered the type shown above in the photo with C3731 and pulled my thermo cover finding I already have that type fitted! But poking around with my finger I could not see how that small ring at the bottom of the thermostat, even when hot and extended, closes off any passage to the bypass hose that attaches at the bottom of the thermo housing. There does not seem to be any passage accessible with fingers at all.
I think I read somewhere, long ago, that some 3.8 engine folks have put a restrictor of some sort in the bypass hose to reduce the flow, thus forcing more coolant to the radiator. Ever heard of that? I guess I could experiment with a temporary clamping pliers on the hose and see if there is any difference. Thoughts?
