In a Vauxhall Vectra, the water temperature sensor is typically located near the engine's thermostat housing or on the engine block itself. It is usually positioned in the vicinity of the coolant hoses, allowing it to monitor the temperature of the engine coolant accurately. Accessing it may require removing some components, depending on the engine configuration. Always consult the vehicle's service manual for specific details related to your model.
lower radiator hose
Because most if not all vauxhall engines are air cooled, hence when you are driving the temp comes down

check around the small rear windows, bath sealant can help.
I'm guessing, but the coolant level sensor is probably in the overflow bottle and it is low. This is so you notice it before the radiator itself is low.
Same problem vectra heater only blowing cold checked water coolant and it was empty. Topped up now blowing hot just hope I not got head gasket probe

The most common cause for the water temperature to rise is a nonworking thermostat. Another common cause is a nonworking water pump.

i took my windscreen washer pump off and cleaned it and cleaned tubes attached,put pump back on resorvoir but water still not coming out properly from front washer nozzles,any answers
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
