Temp gauge falling

#1

Quote:

Driving my Brava yesterday (yes, bring it on, it's Italian blah, blah,
blah)
I joined the motorway and gave it a boot through the gears up the slip
road.
Once I joined the motorway there was a stink of petrol. This eventually
subsided, I can't be sure it was my car or another one and may be purely
coincidental.

As I drove along the motorway I saw the temp gauge start to fall very
slowly. It continued to do this until it stopped at around the quarter
mark. It's never sat completely steady but usually bobs around either
side
of the half way mark. I did about twelve to fourteen miles on the
motorway
and the gauge would rise a little and fall to a quarter just like it does
when sitting at half way.

When I reached my road home - four miles of country road - It rose to
nearly
half way and carried on as normal. So, should I be concerned? The only
reason I can think for this to happen would be a thermostat sticking open.
Anything else?

When driving the car yesterday I saw the gauge fall swiftly from half to a
quarter. It then bobbed up to half and straight back down. I then saw this
a couple of times more. So, it's the good old Italian electrics as was
suggested. Hardly surprising.

So, gauge or sender? My HBOL only mentions the coolant temperature sensor
that is part of the engine management. Does anyone know if this also does
the gauge or if there is another for the gauge that isn't mentioned?
