Hello list-
We just successfully completed a 1000+ mile trip from York, PA to Orlando
Fla.
Twice during the trip the dreaded flashing led on the water temp gauge
started flashing.  Both times I checked both the tank and the overflow and
both seemed normal.  Neither appeared low and they were quite cool even after
12+ hours of continuous driving.  The Temp gauge stayed at a normal level
both times.
After checking the levels and plugging and unplugging the sensor the light
went out. Before we leave for home after the 1st of the year I am replacing
the pressure cap and the sensor.  Any other Ideas...?  I don't think that
there is any thing major happening but seeing that light flashing in the
middle of the trip sends my heart into my stomach.
Thanks for your help.
