Firstly

Its far easier to replace the tank with a known worker :y

secondly the temperature sensors have nout to do with the expansion tank theres one on the block and one on the rad

the one on the engine does the temp guage

Hi all
I have a Vauxhall Omega CD 2001
 ......

which engine?
The tank contains the level sensor, just replace the lot, about £35 IIRC.
V6 temp sensor live right at the back of the V in the centre, if your gauge isn't moving at all I'd suggestthe wire hass come off the sensor.
4 cylinder ..... sorry, don't know. ::)  :y   :y  :y  :y

I think it's still at he back some where, I'd look for a detached wire with spade terminal first though.

The header tank has the low level sender/sensor in it, if it's goosed, you need a new header tank.

Your temp gauge relies on the engine temp sensor which I think sits at the back of your engine (mines a V6). If the wire has come off, then you'll get zero reading on your gauge, if you're getting spurious readings, then it could be the sensor is u/s .... but I'd still suspect that the wire has come off. When you find it, if you ground the wire (ie touch the engine) you should get a full deflection of the gauge ie read HOT!
