Any response appreciated.  On the road and my 90 Carat engine temp
warning light started to flash rapidly.  Gauge needle reads just above
half or 3/4- normal for this car for the last 50000 miles.

Which can I believe, or is there a reason for the condition that might
be known?  It has never done this before.

Thanks in advance,
