I hadn't really considered the t-stat.  The car blows warm air _very_ early
in the winter, within a minute of starting typcally.  This is -30F winter,
mind you.  Part of my says that means it warms up fast.  Another part of me
says that the heater core isn't supposed to get fresh coolant until the
t-stat opens.  Which one of me is correct ?

Look at the cap on your resivour some time.  If the resivoir overflows, it
shoots out of the cap.  My returned pentosin turns into this ugly black
froth with bubbles in it, and spills out the top.
