A thought came to me , "maybe theres a fuse for the temp guage", checked manual and its said "FUSE 24 COOLANT HEATING" am i right? because when i checked the fuses this fuse has been removed! could this be the reason my temp guage isnt working?

Does the fuse holder have both sets of contacts? I suspect that it's for use in other colder countries  :-/

i think you're right there i just tried to put the 20a fuse in and it wouldnt stay in  :-/
looks like the fuse theory is out the window

Is it an MOT fail if they temp guage isnt working?

I doubt it, very much.

With regards your other, cam-wear thread.  I also don't think there's anything wrong with your cams.

Ours  was getting quite noisy (tappets) towards the point when I did the HG.  Pretty sure this was caused by oil degradation due to mixing with coolant.

If you don't know for certain that your 'mechanic' did an oil change after all the work, I would do one very soon, using genuine oil/filter.  Ours is dead quiet following this (and a ten minute drive to get good oil all around and into the tappets).

I hope its not an MOT failure ..... but obviously i need to know what the engine temp is, although my cooling fans are cutting in, i dont know if they are cutting in at around 90 like they should or 100 like they shouldnt, really cant afford the HG to go again due to overheating 
With reguards to this loose connector ive found would taking the cam cover off (again!) make it easier to see where it possibly goes at the rear of the engine?

Not especially.  Taking off the vac pipe that goes to the EGR, and HT leads off the dispack (does the 2.2 have a DIS?) makes visibility a lot easier.  Label up the order of the leads on the DIS and the leads themselves before you take off.  Then maybe with torch and small mirror you may be able to see enough.

Can you get this unconnected wire into a position where you can photograph it?

I wouldn't take the cam cover off just to find the temp sensor :-?  . I believe it's towards the back of the engine though (mine's a V6 & is a b1tch to get to .... right at the back of the engine  )

i spent 2 hrs feeling around at the back last night with no joy lol apart from badly cut and scrapped hands , fingers and wrists, the actual loose connector looks just like the one you put a picture up of on the first page of this topic, but with a flat plastic covering rather than the red pictured 

[Abiton]

Then that sounds exactly like the one that should be on your gauge sender.  Take off whatever is on there, and try that wire instead?

[portomega]

i'll give that a try  im off now for my 12 hr night shift shall spend wats left of the day light fiddling around again with this dam thing  hopefully! i'll be back in the morning with good news

If you ground the wire that goes to the sender unit, then the temp gauge should go to red/hot section of the gauge. you cold try this wire you've found  .... I'd stick a muti-meter across it first to make sure there not 12 volts on it.

Right final update on this dam temp guage lol fiddled around for over an hour last night in work trying to find where this loose connector goes but no joy, and couldnt get what is plugged in off  im giving up! Aslong as its not a MOT fail im happy to leave it as it is, and after getting ripped off to the tune of £833 for my hg , i cant afford to get a garage to sort it just yet 

[ffcgary1]

Is'nt the temp sensor screwed into the coolant bridge between the cylinder heads?, as i am sure i have seen it there, remove the plenium and you should be able to see the bridge and reconnect it.

4-pot. 

I really hope someone local to this fella can pop round and help him out...

ooPS SORRY  must remember to check model before typing. Any way i notice another problem here, he has got 2 cylinders missing.
