Thanks Mark...

I've seen similar comments in the archives ..but, from the circuit, the temp
sensor is connected to the temperature sender - which is a
resistance element ...so I don't see how coolant level or coolant chemistry
can affect things.

I suspect hat something is wrong at the instrument gauge end - but it's
puzzling.

For example, I look at bently and it shows the voltage stabilizer with three
connection - on my van there are three legs to the stabilizer (looks like a
big 3 legged transister)
but only two connectors for it on the plastic 'circuit board' - no mention
of this in bently.

Also, there is no explanation that I can find as to how the flashing lamp
works  ...I presume it must be when the
sensor resistance gets into the extremes of range - specifically too hot..
that the lamp is set off.....

If this is the case then I don't really see the point of the indicator lamp
if all that it is doing is acting as a warning lamp to the gage.

Is it possible when the electrics are working correctly for the lamp to
flash but the temp gage to be n the normal region?
