Hi all
I have a Vauxhall Omega CD 2001
A warning come up saying check coolant level,, Also the temperature needle has stopped working it dose not rise at all,
A mate told me that he thinks its the Coolant tep sensor, So i got a new one to day and removed the header tank I see a plug underneath
the tank but I cant get it out by turning or pulling it is there a certen way you remove this  

[tmx]

Firstly

Its far easier to replace the tank with a known worker

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  

[dave88]

aww so 2 in total

[tmx]

yep one for the ECU & one for the guage

[dave88]

Aaa wonder witch one he sold me  :-/

[dave88]

[tmx]

[dave88]

 ......

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.

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