As I wrote Ian separately yesterday, Ken Wilford advised me simply to
top off the expansion reservoir with coolant to ensure that the probe
was always covered with coolant. It worked. No more blinking. No more
gauge pegging over pretending that the engine is overheating 30 seconds
after firing up.

I hear that the uncontrollable blinking is often caused by a failed
capacitor in the gauge itself. Sounds like you checked everything else.
