It is quite possibly just a weak connection in the dash wiring or the
cluster itself. A sudden electrical surge can trigger the blinker
circuit in the gauge. For example I have seen cases where each time the
radiator fan kicked on the coolant gauge led would flash a few times.
Also seen where turning on the headlights would cause a few blinks.
These were on pre-86 vans, diesel and gas. The later wiring setup is
more robust. None of these had anything to do with the coolant level
sensor system itself.
