Hi, Can anyone point me in the right direction, I have just bought a W reg Omega Saloon CD 2.0 and the temperature guage does not move, Could someone tell me what it might be and how i can sort it. Many Thanks John
-
Is the sensor connected? Have you tried grounding the wire for the sensor? Grounding it should give a full deflection of the gauge.
If you have a look though recent posts, the same question has been asked & other answers are there. :y

Where are you?
Could be a knackered stat (does it heat up if left idling for 30 mins?), sensor, gauge or wiring.

HI Thanks for the replies, I am in Glossop, There is no movement in the needle at all and the car does not get that warm , Also how do you ground the wire? Once again many thanks John
-
....
Also how do you ground the wire? .....
It's just another way of saying connect it to earth/chassis/0volts ie find a nice clean bit of engine & touch (& hold) the connector to it. :y or add a longer bit of wire to it & connect it to the negative side of the battery (terminal closest to the front of the car) ;)

Hi Thanks Andy for the advice. John

Hi Andy , Cheers mate grounded the wire, gauge is fine what do you think now could it be the stat. John

How's your heater, does it get warm? If it does, I'd suggest your car is getting hot and the sensor is goosed.
If your heater takes an age to get warm, then your engine isn't getting hot & it's your stat. :y

Hi Andy , This site is great , You have hit the nail on the head and it is your second option the car eventually does get warm and meets your description exactly, I have looked in the Haynes do i have to get a stat and housing together ? Could you point me in the right direction. Cheers John

Hi mate :y There isn't a 'howto' for this yet in the Maintenance Section but it is dead easy to do on a 4 pot. You can fit a new thermostat on its own, you do not need to replace the whole housing.
The thermostat housing is on the right hand side of the engine (looking from the front of the car) just below the silver cam cover. There is a large diameter hose going to it from the top right of the radiator. It is held on by 2 torx bolts ( I believe T11 IIRC). Partially drain the coolant into a dish via the radiator drain tap (red round handle on right bottom of rad, accessible from under the front of the car) with the expansion tank cap off. Undo the large hoseclip & pull off the hose from the thermostat housing & tuck it out of your way. Now remove the small hose below it ditto. undo the two bolts & remove the housing. If the silicone 'o' type seal is intact, you can reuse it with the addition of a thin bead of 'instant gasket'. The thermostat is removed from the housing by pushing down on it and twisting to free the fixing lugs. The new thermostat is fitted by doing this in reverse :D
If the sealing ring has been damaged on removal, then you can just refit the housing using 'instant gasket', but let it 'cure' for a few minutes before refitting. Refit the hoses, top up your coolant with the stuff you saved & it's done! :y
Note: I do not know the VX part no. but the one I bought was numbered 600K
Here are a few pictures of the stat housing & Seal. When you buy the new stat, make sure this shape seal is included.

As per PM:
Get the stat from a Vx dealer, it comes with housing and a rubber gasket.
Its located on the passenger side of the engine, right at the front near the cambelt cover:

Two torx bolts top and bottom, forget which size. Just remove those and off it comes. (drain coolant & take the coolant hose off first)
Smear a little Vaseline around the gasket, and re-assemble :y
