temp gauge not working

[brod]

having problem with v6 supercharged statesman, temp gauge not working is this linked to fan not coming on?

G'Day Brod and welcome.
The fan not coming on is linked to the coolant temperature sensor which tells the ECU to turn the fan on as the engine's hot - the temperature gauge sensor is separate although it is located near the CTS......so they are both independent. Check the lo speed fan relay and the larger fan relay in the relay box next to the battery. Sometimes the actual gauge needle 'sticks'
Does the cooling fan come on with the aircon?

Sounds like the temp sensor has come off. Its' the little plastic rectangle on the end of a wire, just below the thermostat housing. If it is off, just slide it back on and hey presto.
