Hello to all,

First some background:

Last spring I replaced the water pump in my wife's '84.  Last winter, the
heat worked OK, and the temp gauge would pop up after 3 - 4 miles and sit
about dead center no matter what.

Since I replaced the water pump, the gauge never rises more than a bit above
bottom, except in slow stop and go traffic.

Ah hah, you say.  It's the thermostat!  Well, with cooler weather coming
along, my sweet wife asked me to fix her heat.  Easy job, I think.  I'll
just go ahead and install a new thermostat.

Well, the old thermostat was working fine.  I installed the new one, and I'm
not sure yet if there was a change.  I bled the system, or at least
attempted to.  I couldn't get any air out of the system.  I find it hard to
believe that I could have replaced the thermostat without letting in any
air.

I let the van sit there and idle for about a half hour, but it never got hot
enough to fire up the radiator fan.  I did jump it, and it ran on both
speeds.  It starts well and runs well, but I'm not at all sure it's running
right!

Anyway, do I have a problem?
