Another rite of passage, I guess.
This evening, after driving for about ten minutes in the bitter cold
here in NJ, my temperature gauge started going up pretty quickly, until
the red light started flickering.  So I slowed down, and then, almost
immediately, it went back down to normal.  I had a van-load of screaming
five-year-old girls inside (it was my daughter's fifth birthday), so I
couldn't hear whether then fan had turned on and/or off.
After I got home, from what I could tell in the dark, everything seemed
fine.
Any thoughts on what might have happened?  I can't do any diagnosis
right now, but  I'd appreciate guidance on how to proceed.  Thermostat?
Only other symptom during this fateful voyage is that the alternator
belt, which has been squealing a bit on start-up, was squealing pretty
much the whole ride instead.
Thanks,
Jeff
