Because most if not all vauxhall engines are air cooled, hence when you are driving the temp comes down

For this job you need an angle gauge to attach to your socket bar,they are available for about
Unless you have the triple information display on your vectra there is no warning light indicating low coolant apart from the engine temperature gauge.
remove trim around clocks, remove clocks, replace bulb in back. hope this helps
could be a number of things, more than likely the sensor, the wiring or the gauge itself, i'd take it to a garage then you can blame them if it goes wrong :P
Possible causes of gauge not working. Faulty gauge Blown fuse. Open circuit in wiring to the gauge. Temprature transmitter in engine faulty. ( most probably the actual fault ) Lack of coolant in the engine.
I am wanting to know the same thing. I have a 1996 Diesel, and am running at just over 80c.
replace temperature gauge
around 90ºC is normal
Because it's made in Britain, that's why. :)

float inside tank could be stuck, if its electrical gauge it might have a fault, or petrol leak
