Hi Scott -- before I pester the group with a question that might be
common knowlege, I figure I could pester you with it first?

People write about putting cardboard in front of the radiator. I think,
"I don't get it. The thermostat isn't an on-off switch, doesn't it open
just as much as needed to keep the coolant at the right temperature? If
the coolant coming back from the radiator is darn cold, won't the
thermostat just crack open a bit?"

Or maybe it does a poor job regulating temperature when it has to do
that "crack open a little bit" thing.
