around 90ºC is normal
Because it's made in Britain, that's why. :)

its broken
hole in fuel sender gauge float
float inside tank could be stuck, if its electrical gauge it might have a fault, or petrol leak
Because most if not all vauxhall engines are air cooled, hence when you are driving the temp comes down
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.
my oil light pressure light comes on when my car is at rest yet when I am driving it goes off or if I keep the rev count up slightly it is a vauxhall astra 56 plate.Any ideas what this is most likely to be. First be sure the oil level is correct and you are using the correct weight oil for that engine and climate. Then check that the engine idle speed is correct. Then check the oil pressure sending unit for accuracy with temporally installing a manual oil pressure gauge. If all that checks okay, you probably have a tired engine with worn bearings and oil pump.
18 or 20 gauge
For this job you need an angle gauge to attach to your socket bar,they are available for about
Engine oil pressure will vary depending on if the vehicle is in an idle state or not. However, on average, it should be around 40, which is typically half of the gauge.
There is a warning light on the dash that will come on, the dash may also start making the alarm noise depending on yerar and trim level.
